I'll start off with the meh part of the cable. For the price, the build quality is okay, but not what I expect from a product costing over $40 at the time of purchase and review. It's not terrible, but I can definitely see problems down the road with the cables going from the main neck part up to the plug that goes to the IEM.Other than that, the sound quality is phenomenal. Can't notice very much difference between using this and using the direct wire on my DAP. The latency is low enough on most of my devices that I can actually watch content without any obvious latency between video and audio. The only downgrade I've noticed in audio quality is that when there is no music playing, there is a slight hiss for a few seconds before it goes silent. Couldn't notice it while listening to anything however.  Read Less

1. Good microphone. No complaints in the past week.2. Great sound quality. The Qualcomm CSR8645 really does shine in this device with the 24 bit DAC. Most other bluetooth devices skimp on including a good DAC which is really important when you have a high definition codec like the latest aptx or LDAC.3. Hardly / barely any music cutouts or interruptions when I leave my phone upstairs and go downstairs at the next level. Sound does cut out when I'm at the gym and the phone is a few yards away when metallic equipment in between. This is to be expected.4. Able to drive my KZ ZSN for around 10 hours with no problems.5. Charges in less than two hours using the included cable.6. Request to manufacturer: Please make a version of this like the LG neckband ones with retractable cables. That would be really awesome.  Read Less

Works with my Yinyoo KZ ZST IEMs perfectly.The sound quality is 99% as good as wired, but with the major benefit of being wireless and not having the cord bouncing/rubbing while moving/exercising. There is a very slight noticeable white noise during quiet parts or no music playing, but that's fairly typical of most Bluetooth headphones I've tried.The aptx codec certainly helps lower latency as well. It's not as good as aptxLL, but the couple ms latency really isn't noticeable unless you really look for it. It's perfectly sufficient for watching videos/movies, but the lag shows in games where you're listening for specific audio queues and are used to a very specific timing. Casual gaming is fine.Range is great, but of course that's very dependent on your source device as well. My laptop with an older V4 Bluetooth has skips occasionally when I'm in a different room. My cellphone with Bluetooth V5 works from the other side of my house on a separate floor with 0 drops. Bluetooth certainly has come a long way.100% would recommend this to anyone looking for adding bluetooth to their favorite IEMs.  Read Less
