Review on NewFantasia Replacement Audio Upgrade Cable Compatible With Audio-Technica ATH-M50XBT, ATH-AR3BTBK, ATH-SR50BT, ATH-ANC9, ATH-ANC7B, ATH-SR5BTBK, ATH-S700BT Headphones 2Meters/6.6Ft by Loud Forrest

For starters I'm using this with the M50xBT. The original cable was so bad that when plugged in a quarter inch adapter (tried multiple plain, unthreaded adapters) it would play through one ear and sound like I was underwater. If I pulled it out slightly it would sound normal. This cable works perfectly with its threaded adapter and regular ones I had sitting around. Also at the plug end it has a metal coil for additional stress relief. Exceeded my expectations. Definitely an upgrade!
