A:AnswerThey work well with my hearing aids, which have mikes behind my ear. I can still hear most speech in the gym, while also hear and understand the tv programs on the treadmill system.
A:AnswerThe MDR-ZX110 does not come with a 3.5mm to 1/4 inch stereo adapter. You must provide that on your own, but they are cheap and can be found at pretty much retail store that carries audio equipment (BEST BUY, Walmart, Kmart, Target, etc.) for very cheap. To be clear the ZX-100 "Plug" on the cord is 3.5mm to fit a 3.5mm jack (the plug is on the cord and the jack is part of the equipment you are plugging into).
A:AnswerThey really endured a lot of abuse from my sons, they throw them around and usually carry them by the cord and they still work good as new. They’re very durable.
