HiSound POPO Review

HiSound POPO Review

I would like to thank HiSound for giving me a pair of these wonderful headphones for review! As always my reviews strive to be as unbiased as possible, and I’m always welcoming suggestions on how to better organize my reviews, so if you have any comments, tips, or advice feel free to comment and let me know!

Packaging and Build

            The packaging is very bland, and does not offer much other then protection during shipping. This is one area I think could be improved, seeing as how companies like DUNU which price similarly tend to come with things like carrying pouches. It did luckily come with a package of different sized ear tips, no adapters or carrying cases here though.

            So how is the thing built? Well the wood is very aesthetically pleasing and the units themselves are very lightweight and comfortable. They have a very good fit, one of the better that I’ve tried. However one thing that does bother me is that the headphone cable picks up a lot of noise when brushed up against or touched.

Sound

           

            One thing that strikes me immediately is that these headphones have a very soundstage width that is both extensive and very controlled. There is depth to some extent but I’ve noticed that depth is often hard for IEMs (In Ear Monitor) to portray and that proves true here too.  But they’ve nailed soundstage in my opinion for an IEM in this price range!

            These, like the DUNUs, fit into the bass head category of in ear headphones. It sounds to that bass below 80 Hz is boosted and it does not bleed into the midrange at all, which is very pleasing. The bass has nice punch, but leaves a little to be desired in terms of detail. It seems a little punchier then the DUNUs house sound, with less mid bass. This results in improved vocal reproduction.

            Were these shine is in the mids and highs, which I think are very tonally correct. Female vocals come through with detail, presence, and warmth. Highs are not sibilant and are very well controlled, they don’t have shimmering detail or an airy feel to them but they are very pleasant and laid back. Frequency response is good, they seem to go down pretty far, not quite as far as they clam I think but pretty good nonetheless, upper frequency is equally well extended.

            So do I think they are worth the asking price of $90? (It can be found for less through authorized retailers) Yes I do think its worth the price, the soundstage is most impressive and possibly the best I’ve heard under $100 in the IEM market. In fact I think these are my new favorite in ear headphones that I own. The only thing I want to see changed is I would love to see it include at least a basic carrying case since most people will be using these on the go and for the price they should include something. With that said I can highly recommend these headphones!

HIFIMAN/HeadDirect RE 272 Review

HIFIMAN/HeadDirect RE 272

A Little About Myself

I am very honored to have been one of the many chosen that were able to review this unit and I want to thank HeadDirect and HIFIMAN for putting this together. I don’t have a lot of experience with IEMs and so this has been very fun and interesting. I would say I have decent experience with over the ear headphones I have heard many headphones and on a lot of different amps which I hope will allow my review to be a little more informative and useful. I am not down with all the audio terms, so I can only hope that someone will find this review useful. Thank you again and happy listening!

Packaging

When I received this unit I was surprised by how nicely the case looked, the pictures don’t do it justice and everything is packed nicely in the box. However it looked like it was already opened I don’t know if you guys test them before sending them out or not? But everything appears in great condition and the headphones themselves are very appealing to the eyes.

Sound (With Burson 160 - MS II+)

Pros

The highs are well done, not too bright, musical and a little forgiving, this works great for jazz music and classical as well as older rock. I’ve found that it has a good center image with a lower mid field type soundstage it seems to be very dynamic in its soundstage though. One moment it can be very close and intimate if the music calls for it and on other tracks can have a pretty decently large soundstage, for the most part however it seems to sit in the lower midfield to me. Very smooth,detailed, and well balanced mids very good for vocals like Norah Jones,Patricia Barber, even male vocals sound astonishing, such as Tom Waits Etc. One other area that this does well in is classic rock, despite that it could use for a little more bass the handling of the highs is done so well that I still think its great for classic rock. Generally I think that the highs are to bright or sibilant on most headphones but despite not being petite or shy in any means these manage to sound good on tracks that would normally sound too bright to my ears. Trumpets are rendered near perfect and saxophones sound amazing, cymbals are very defined and not grainy at all.

Cons

I thought the bass had a great balance as well as good detail however some may find it a little petite and in some older rock I found my self wanting a little more bass. Another thing is that despite its great overall balance I felt that it lacked a little warmth, if you like warmth or tube like sound then these might not be for you but if you can pair them with a tube amp as I did you will be rewarded.

WIth Little Dot MK III - MS II+

When I used it with my Little Dot MK III I thought it brought some of the warmth and bass that lacked in the Burson however at the cost of detail. I really think that these headphones prefer tubes which is odd for IEMs or at least I think thats odd. Despite the lack of detail the already wonderful mids now have a very nice and silky presence. With this amp the soundstage was pushed back a tad making it sound a little wider as well. These IEMs really do change quite a bit with different amps. Rock with these headphones and this amp sounds godly, very soft highs and more low mids and bass make this a absolute winner for classic rock! One song “Gypsy Wine” from Paper Garden is really bad on most headphones due to the annoyingly bright sound but on these its listenable which is saying a great deal!

Directly out of iPod Nano 5th Gen

Direct out it lacked the soundstage that it is capable of, it lacked detail and the highs lost its magic. I don’t blame the headphones for this one bit obviously the feed direct out of an iPod is not very hifi unfortunately I don’t have a portable amp or dac to test this with. Non the less it was still very good for on the go listening and would be fine for commutes or other things but if you want the best out of these headphones you need to have it hooked up to good equipment.

Comfort / Isolation

Very comfortable with tons of options for the right tip size depending on your preference and ear canal size. Lots of good and useful adapters are included which is nice. One other thing I really liked is that the connector, instead of being L shaped or straight it has a curve in it that is not only stylish but also practical. These headphones seem to block out a good amount of noise and would be good for an airplane or bus ride I can’t say how many DB it blocks but if I had to guess I would say somewhere around 20 DB. My brother actually blew a blow horn next to my door and I was unable to hear it listening at normal volume with these! The cord appears to be the perfect length to connect an iPod or other personal source without being long or cumbersome.

Extra Thoughts

Having not heard many IEMs I would say these are hands down the best I’ve heard, comparing them to full size of course is unfair but let me just say that I prefer these over all my other headphones other then my K702s which I still like a little more overall. Would I buy these? If I was looking for IEMs then yes I would definitely look at these, they do not overdue the bass like the other IEMs I’ve triad do, which is a big plus for me.  The tonality is also quite special almost a mix between the AKG and Ultrasone sound signature.

Specific Songs (test conducted on Little Dot MK III for the below)

Rock - Pink Fold - The Wall  Side A - Mother

Has a very musical sound right off the bat, non fatiguing and very natural sounding. It sounds great with this like it was meant for this song, I think this song demonstrates how well it does with classic rock. The highs are not over powering or under whelming they are simply dead perfect for this type of music. The mids are clear as ever and it renders the vocals very realistically. You can hear the guitars with great detail, every instrument is very distinct and the voice is dead center, as I mentioned before the center image is very very good on these headphones. These headphones let the song portray the emotions that were put into this recording very clearly. 

Jazz - Patricia Barber - Modern Cool - Post Modern Blues

Wow the bass! This track was mastered with too much bass IMO but other then that is a top notch recording. Most headphones will render the excessive bass muddy, however these do not! Very clear you can hear as the strings are plucked on the bass guitar and there is detail! Wonderful detail, not muddy in the least it carries the multiple note bass easily across its small drivers with deep impact. Patricia’s voice is rendered properly and very realistically as well, very smooth and relaxed and a pleasure to listen to. Very distinct instrumentation found here as well. 

Alternative - Tom Waits - Alice - Alice

Very good separation of the instruments, the saxophone on the further left is easily distinguishable from the center saxophone its like night and day separates them perhaps a little too much. It almost sounds like the left saxophone is slightly behind me which is a little odd. Tom’s voice holds a very good tone not too heavy or syrupy like some headphones can be on this song. It carries the somewhat dark texture of this song very well. The trouble sounds a little grainy but that could be the song I’m not sure. 

Metal - Marilyn Manson - Antichrist Super Star - Dried Up, Tied and Dead to the World

Perhaps as I’ve mentioned before a little bass light, but it scales well going load. I don’t play stuff as load as most but as load as I was willing to listen (also don’t want to risk damaging these haha) there were no signs of distortion. Marilyns voice is down as good as well I think that’s the key to these headphones, very good vocals and mids with highs that are forgiving. These did not get my blood going though, I think the  slight lack of dynamics on these does not suit heavy metal. Its not bad don’t me wrong but I think I’d rather use some Grados or Sony XBs for metal. 

Folk - Noble Beast - Andrew Bird - Tenuousness

The highs felt a little too forgiving on this track and the lack of a little bass made it feel a flat. I can’t say that I really like these headphones with this specific song. The guitar had good detail but felt compressed. It felt like everything just lacked dynamics. 

Electronic - Trifonic - Emergence - Emergence

Gobs of detail, fast pace and rhythm and not overly done bass! Great for electronic music that’s what I say. The drivers have a very fast response and keep up well with the fast pace. Really gets your heart going here. I keeps the smooth graduated sounds smooth, and keeps the sharp crackling sound sharp. From what I’ve heard with a lot of headphones that I have that’s very hard to do right and these do it!

Burn In

Last but not least burn in. I have about 30 hours on these and have noticed very little burn in effect. Burn in for the most part seemed complete after 10 hours. After that 10 hours very little if not nothing seemed to change.

DUNU DN-17 Crater Review

Review of DUNU DN-17 Crater

A Little Information

            I would like to thank DUNU for being extremely generous and sending me yet more gear for review! It was a bit of a surprise to receive these headphones, as I was not aware of entering any contest or anything of that sort and was not expecting them. However I do of course welcome new gear for testing, so it was a lovely surprise to see these at my door.

            For this review I will be using the DUNU DN-17’s with my Burson 160 Headphone amp paired with a Music Streamer II+ as well as testing on my 2010 MacBook Pro. I feel that testing these headphones out of the desktop setup will enable me to squeeze every ounce of pleasure out of these headphones, were as testing with my laptop will be a much more real world scenario, since a lot of people will be using these headphones with something similar.

            For those of you who are unaware DUNU is a newer audio company who is aiming to make budget minded IEMs for both audiophiles and general consumers alike. Most of their products are aimed at people who enjoy bass but don’t let that deter you some of their products are quite good for the price and may satisfy more then that nitch of “bass-head’.

Included Items And Build Quality

           

So what’s included with the DUNU DN-17 Crater’s? Well quite a few things actually. Packaging was adequate in my opinion; nothing special about it but it was done well. The box is nicely designed and reflects on them for wanting to target the budget-minded consumer. It appears visually attractive with a simple design to it that is almost Apple like. But enough about the shipping and box what’s inside? Well how about the following:

• ·      Leather Carrying Pouch
• ·      Hard Plastic Carrying Case
• ·      2.5mm to 3.5mm Headphone Jack Adapter
• ·      Shirt Clip For Headphone Wire
• ·      Airline headphone Jack Adapter
• ·      DUNU Microfiber Cleaning Cloth
• ·      8 Tip Pairs Of Different Sizes

The DN-17s have a more normal shape to them then some of the other DUNU in ear monitors (IEMs) I think they look great in terms of pure visual design and is of more attractive design then the DN-12 and DN-16 in my opinion. The comfort however was a little less so then the other DUNU models. Due to being a little smaller I found myself finding that they just are not as comfortable as some of the other models. Don’t get me wrong though these are not extremely uncomfortable they are just not as good as some of the other DUNU models in this respect, Certainly not bad.

One thing that is fascinating is that according to DUNU these wires are made of silver. Now this is quite an impressive feat for a consumer-marketed product. Now as some of you may be aware a lot of higher end cables for headphones or otherwise tend to use silver since it is a better conductor, will that in practice affect the sound? You’ll have to see, so read on!

Sound

            In the next part here I’m going to break down the review of the actual sound quality into sections because I feel that it portrays the information people looking for more effectively. I do this because I feel that it is easier for the readers to find what interest them faster. If you have any comments, advice, or even criticism let me know, I want to hear from you!

            Soundstage: Soundstage has always been a very important thing for me. I want the music to take into account the acoustical space in which it was recorded and for the headphones or speakers to be able to reproduce the sound of the room and not just the instruments. I want to be able to hear the placement of the instruments in that room so to speak.

I feel that these headphones do in deed have a decent soundstage, nothing to be wowed about but certainly not bad for an IEM. The sound stage itself is just ok, not large or anything, you certainly won’t feel like your in a cathedral but its placement of instruments is fairly good. One thing that these DN-17s do well is center placement. With some headphones I’ve heard the soundstage was wide but really lacked a center image making the sound rather odd to listen too. However the DN-17s do not suffer from that problem, center image is fantastic and one of the strong points of these!

Bass: This is definitely a place that DUNU in general seems to have nailed. The DN-17s are no exception. Bass is very well extended and not at all sloppy sounding. I would not go so far as to say that it’s a super tight bass but it is above average. Detail in this area is great and you won’t have to worry about added bass bleeding into the mid range either. Again DUNU markets most of their headphones to the bass head audiophile and they have nailed bass reproduction!

Mids: Some things here that I like and some that I don’t like. The lower mids are clean, detailed and have the appropriate sound level. That’s were things starting going downhill a little. About dead center in the middle frequencies it sounds like the volume is boosted a little which can make some vocals edgy and harsh sounding. Then we get to the upper mids and it seems to drop out a lot and losses a lot of detail. This tends to make it sound a little scratchy too.

Highs: Balance is once again restored in terms of sound levels. Detail is returned and it’s very musical. It has a very soft sound to it, which is very nice and pleasing. It has detail but does not throw it in your face instead it lets it out gently as it whispers into your ears. However extension is not the best, it is however better then the DN-16s and DN-12s in my opinion. Although rated to extend to about 22KHz in my opinion it really starts dropping off around the 17KHz region. Leaving some of the highest frequencies lacking.

Overall: Very good, and it has its strengths such as bass clarity and punch, as well as soundstage center imaging and instrument placement. However it also has its weaknesses, chief among them would be the horrible upper mids, which lack detail and sound levels and are not at all complemented by the boosted center mids which can make it sound painful with some vocalist. Do the pros out weigh the cons? I guess it depends on the type of music you listen too. For a lot of music I would say that these are very good. Pianos have a very nice sound on these and head banging music will sound great as well! But vocal jazz or folk music is not its strong suits.

Comparison to DN-16 Hephaes and DN-12 Trident

            The first thing you will notice going from the DN-16 to the DN-17 is that it has a better and smoother overall sound balance. I’ve always felt the DN-16s balance was rather odd but the DN-17s have solved this problem. Though in my opinion the DN-12s still have a slightly better overall sound balance.

            Although the DN-12 may have a better balance it lacks things that both the DN-16s and DN-17s both have, and that’s detail. If your upgrading from the DN-12 your going to immediately notice tighter bass and better clarity as well as more detail across the board. How does the DN-17 stack up against the DN-16 in this regard? Well I’d say quite well I would say that the DN-16 still has a leg up on the DN-17 in terms of bass punch and detail overall.

            One place were the DN-17s definitely have a leg up on the DN-16s in my opinion is in the fact that they are laid back. I often found the DN-16s a tad bright for my taste and the DN-17s work on that. With it being more relaxing and more something I want to put on to relax too.

            So if I could only have one, which would it be? I think it would depend a lot on what I’m listening to and what mood I’m in. For my taste in music, listening to a lot of folk and vocal jazz I’d have to stick with the DN-16s however I would say they are both very good and I can totally see someone liking the DN-17s more for other types of music. Heavy rock, metal, maybe even rap or types of alternative may sound better on the DN-17s and I do prefer them on a lot of music so its more a matter of taste since I find that they are both are on the same grounds of overall quality.

Extra Thoughts

            I’m very interested, as I’m sure you are too on how much the DUNU DN-17s are going to cost when they release. Unfortunately I’m not able to provide you with that information. How much do I think they are worth? Well in terms of pure sound quality, I’d price them similarly to the DN-16s if I were DUNU. I think asking more then $100 would be asking too much for them. But I don’t want to speculate too much on that.

            Another question you might have is when the release date is? Well I've asked DUNU and they said that they are aiming for a March release, so if these sound like your ideal headphones then you'll be waiting till then. Another thing I want to point out is that these headphones really need to be burned in. When I first heard these I thought they sounded awful, so I put at a decent sound level and let I burn in for about 50 hours and they really changed. So keep that in mind if you buy these!
