Shozy Hibiki MK2/MK II High-Definition Headphones Single Dynamic Driver HiFi in-Ear Earphone IEMs with 2-pin 0.78mm Detachable Cable, Mic

Purchased this after seeing a very positive review on an audiophile site. First, the sounds quality was great, though a little too "bright" for my tastes. The frequency response was full and accurate. Nice full bass and clear highs. I did have to tweak the highs a bit with EQ settings, but I am used to Shure products which are known to have a warm/mellow sound so this might just be personal preference.I would have kept them except for two issues. First and foremost, they come with three different foam inserts. Small, medium, and large. My mediums were not the same size. One was slightly bigger than the small but much smaller than the medium. This meant that it kept falling out of one ear. They're a fairly bulky unit so you need a good fit. I tried contacting the seller about getting just the insert replaced since these are likely a 10 cent item, but received no response.Second, the cable is awful. On my Shures (I have 215s and 315s) the "hook" part that goes around your ear keeps its shape really well once you form it. The Hibiki hook was very flexible so it didn't stay against your ear. That, combined with the weird twisted cable they use just didn't work very well. The cable was almost too flexible so it didn't want to "hang" properly. Again, this kept the hooks from staying on the ear so you had to re-adjust everything every 10 minutes or so to keep it all where it needed to be. My Shure cables wrap the ear perfectly, hang perfectly, and can be comfortably worn all day with minimal fuss. Unfortunately, the plugs were not interchangeable or I would have just swapped the cable.These could easily be a 5 star product with some more attention to detail and quality control. The sound was the best I've ever heard at this price point. However, I think the SE215s are well worth the extra cost over these if for no other reason than the more comfortable fit and higher quality.

after 10 hours of burn time, it was good. after 30 hours of burn time. it was very good. after 50 hours of burn time, it stopped at its peak, and I hear more highs and mids...this one has unbelievable mid that comes forward. vocal really shine on this one. there is better ones but those cost at least $250 I have western that cost $250 and this one sound 95% of it. with dedicated DAC/AMP this one shines SIGNIFICANTLY MORE!!! cellos are really good. I don't compare to real-life-like planar magnetic drivers, but the single dynamic driver cannot be better than this. AND it beats a lot of dual armature drivers....even some OEM triple armatures. This is solid proof that dynamic drivers can be as good as multiple armatures drivers IEM, just like Sennheiser did in the history.

The cables look great, and the sound is good, but every time I make a call or receive a call, people complain that they're hearing themselves, almost like an echo. Is there any solution to this?

Received in good condition. Fast delivery. ordered on 31st and received on the 7th(ship to Singapore).Quite a good sound when first came out of box. Will try and burn in to see if there's any improvement.Btw it's really large. even bigger than my IM04. anyway this is definitely worth for this price
