AUKEY Foldable On-ear headphones

When I first received these headphones I was not expecting much, I have owned headphones with similar designs before and the experience was not pleasant. The AUKEY Foldable On-ear headphones was a different experience, the ear cups were very comfortable, and the band did not cause any pain nor did it rub my head at all. The fit of the ear cups was quite nice, by far the best fitting ear cups of this design. I wore these up to 8 hours a day(some days longer) for just over a week. While wearing them I did some yard work, did some shopping and went for some walks, not once at any time did the earphones cause me any pain or dis-comfort, yes my ears did get a bit sweaty but honestly am a person that does sweat a lot.
The bass response was strong and steady, nice thump with out sounding muddy, the mid-range was clean and crisp, vocals were pronounces very well and the treble(high end) was perfectly balance with the mix, there was no ear piercing or "tinny" sound, the over all mix was very pleasant and did not change when the volume was turned up to the maximum. At full volume, on both the headphones and music player, I did not encounter any distortion, hiss, crackling or static, the AUKEY Foldable On-ear headphones do go pretty loud but not so loud to cause ear damage or ringing in your ears.
These headphones use Bluetooth 4.1 for a quick and solid connection and has a built-in CVC noise canceling microphone. You get a 450mAh rechargeable battery that will play up to 24 hours, now the playback time does rely on how loud you turn the volume up on the headphones, the louder the volume the more energy they take to produce the sound. Standby time, when your headphones are off and not being used, is 300 hours, now I can honestly say that I did get a total of 24 hours of playback time from the AUKEY Foldable On-ear headphones, not all at once but day after day usage. I do like these headphones, they produce a really nice balanced sound, they are comfortable and the fit was pretty good, my only negative is for my head the band is a bit too snug, If AUKEY could put a adjustment on the band, maybe a half inch to an inch, but that is just me being picky, regardless they do fit nicely, they just move a bit when I turn my head, but they do fall back into place when my head is straight. One thing I would suggest to AUKEY is to include a carry pouch, even a mesh bag would be nice. Over all I am pleased with the AUKEY Foldable On-ear headphones and highly recommend them.
