Sound quality is good but it's audible outside the headphones. Left speaker stopped working within an year. Got it replaced under replacement warranty. The replaced item has too much bass but no sound quality.

great headphones, noise cancelling works very well, and a bargain compared to other brands

Received a pair as a Christmas gift. I'm blown away. I never use computer speakers, my external computer speakers, or anything else now. I've had them about 3 years and the only downside is that the leather around the ear covers is wearing out and breaking off. The underlay and foam are fine.

I just loved this product and I am writing this review after using it for about an year now. These headphones work perfectly even after 1 year, these have amazing bass and sound quality. These are not only good for listening to music, they're even good for gaming sessions.

Not the best in way of noise cancelling but very good comfortable headphones. I definitely don't regret buying them!

You might think that these headphones are quiet, but I owned a pair of Logitech G230 headphones and while seemingly 'louder', these headphones are much better quality.Excellent frequency response.

Good value, noise cancelling works ok on a plane; Perfect for travelling; Cheap

The battery for the noise cancelling doesn't last to long

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.

Awesome product .

Noise cancelling function was disappointing to me. Moreover playing in passive mode (switched off) has terrible sound (almost no bass). Additionally noise cancelling function generates some noise. Summa summarum: hearing in the noisy environment brings not too much benefit.
