KBEAR BT5 Bluetooth IEM Cable with 3-Button Mic/Remote,Bluetooth Replacement Cable for KZ ZSN/ZSN PRO/ZS10 PRO/AS16/AS12/ZSX/ZSN PRO X/ZAX/ASF/ASX/DQ6/AST/ZAS/EDX PRO /D-Fi/PR2/CCA CRA Earbuds (C Pin)

Stumbled on these when buying new IEM drivers, thought "that'd be cool for work or riding bikes" and I was right.Clear sound, decent range, Ok battery life. Awesome because I can use my drivers!Highly recommended!

Very nice and comfortable to wear.

Extremely dissatisfied with product. Pins don't stay in my JHAudio IEM's and dealing with seller on previous pair that failed sucked. Amazon stepped up and refunded me on last pair that had long pins, the replacement I bought, the ones I'm no reviewing is junk. Will not purchase in the future from this seller as we went back and forth a dozen times trying to resolve the problem I was having. Heading off to WFM to return ASAP!

Replaced the original KZ piece that was similar. The KZ brand would last several days, while these only get a day and a half.

There are a bunch of things that I don't like about this cable.* slow connect compared to Bose, Sony, or Shure* poor compatibility with A2DP hardware offload on android. Audio stops after a couple of minutes. Doesn't happen with any of my other Bluetooth audio devices.* low level background hissing/buzzing noise that is audible during quiet audio.* annoying power saving behavior. During extended (1s or longer) quiet periods the audio is completely silenced and there's a moment when it wakes up again.* can't listen while charging. And there isn't a fast charge either.* "Battery Low!" ok, I heard you the first time. Stop shouting at me every minute. Why not tell me what percent or run time instead of "low"?

Sound quality is good, battery life is decent. I didn't have any of the connectivity problems the other reviews had, but the loud battery low repeated message is annoying.

I like the concept and man this thing has more volume than most TWS I have and I have quite a few. It has plenty of power for IEMs.I didn't like the drops in connectivity. Not continuous drops, like once or twice a day if you are walking around. If they could work on a stable connection I would have given 5 stars.At this price I suggest you try it on general principle.

Update: Something is wrong with the volume. It's too loud overall and twice it has maxed the volume on me. I was lucky enough to avoid ear damage, but that's a big flaw and no-no. Has to be one star for a dangerous product.Tested with some CCA CRA IEM's. The cable has a decent feel and mobility. Having two "big" cases for battery and electronics seems like a lot, but it's the nature of the beast. The USB port cover seems more plastic than rubber, but it is staying in the port so far. Not to bury the lede, but this thing has some power. Don't ever start them in your ears. The automated voice is loud is also loud. Connect and play something first to avoid any hearing damage disasters - and when you're playing them test how loud they really are by snapping your fingers around your head. It's easy to go too loud wit these cables. On the other hand, the power can bring out the best in some IEM's too.Very decent sound quality. Better than two other more expensive cables similar to these. I was getting more powerful bass thump than running them wired with a powerful DAC/amp dongle. The volume/track FF controls seem reversed to me. The "-" is on top and the "+" is on the bottom. Takes a bit to get used to that. Then if you're using a different headset, you have remember it's "normal." Battery life is good so far at 5-6 hours. Recharged in about 50 minutes. Range is pretty good. I was getting about 20ft away out of line of sight with no issues. Overall, can't complain too much for a sub $20 bluetooth IEM cable . This review will definitely be updated if anything fails prematurely; otherwise, so far so good.
