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 Srinivasan Bennett

I bought these because I listen to music and audiobooks a full 8 hour work day and I've burned quite a few pairs of cables just from the stress of my relatively physical work. I have a pair of mid-range headphones that I really like, so I decided to try them out. 2-3 weeks use. I work and play with them all day, then wear them when I sleep and charge them 2 hours after waking up. No problem. Design wise they are bigger than I thought. I'm not giving a 5* rating yet because the materials for the wire parts seem to be of very poor quality and I have a feeling they might just go bad over the next few months. I will update the rating around December 2021 to either increase it to 5 stars or deduct points for bad content. But really, for $40 I'm impressed.
