Review on OKCSC BT3S Wireless Bluetooth Headphone Cable 0.75mm 2pin - Bluetooth 5.0, Apt-x & AAC Support, 20 Hours Playback - Compatible with KZ AS10, ZST; TRN v80, X6, IM2 (0.75mm Jack) by Brian Weese

1. Good microphone. There are no complaints for the last week.2. Outstanding sound quality. The Qualcomm CSR8645 really shines in this 24-bit DAC device. Most other Bluetooth devices will skimp on a good DAC, which is really important when you have a high definition codec like the latest aptx or LDAC.3. Hardly/almost no musical dropouts or pauses when I leave my phone up and go down to the next level. The audio cuts out when I'm at the gym and the phone is a few feet away with pieces of metal in between. This was to be expected.4. Can drive my KZ ZSN about 10 hours without any problems.5. Charges in less than two hours with the included cable.6. Request to the manufacturer: make a version like LG's with a neckband, with retractable cables. It would be really great.
