Do not use for music AS or A Levels, avoid using them for anything like a focusrite as you have to keep the little button held down in order to hear the full audio. For phones they work well but they aren't the best.

I bought the headphones as I wanted noise cancelling at an economical price and the ZX110NA headphones provide exactly this. They are comfortable and easy to carry around as they fold up and don't get damaged like other headphones do. The sound quality is quite good,but when you activate the 'noise cancelling' function it makes a huge difference and really cuts down on external noise. Great for travelling on trains, buses and airplanes!!! Overall, considering their economic price, they are great value and a nice product!

Didn’t want to spend a huge amount on earphones. Used them on a flight and was very pleased with the noise cancellation feature. Would recommend for a set that are reasonably priced.
