Very hard to find. But thats not a big issue for me I bought these solely to use with my ps4 pro and they get the job done nicely. I dont know what the deal is but I planned to get to work riding it but it seems not be be not so reliable. Sound Quality:The BTX300 sounds really good. This seems to have a very real impact to the volume range of the system for me. Dont think this affects the sound. 25 inches. That said, I was disappointed by this style. These greatly increase the comfort of these IEMs and give youa better seal which gives you a better sound. I’ve been wasting money on Nike running sure but I decided to buy my next pair based on reviews.
