Poor quality drivers and strange resonances of the isolation chamber combine to deliver a poor quality reference environment

I would highly recommend the headphones for anyone who wants to listen to audio in a noisy environment.

Whether you are a studio musician or technician, or simply need sound isolation in a noisy environment when listening to audio input from your computer, CD or DVD player, you won't go wrong buying EX-29 sound isolation headphones, especially considering the quality of service you get from this company.

I bought the headphones to use in a noisy office environment.

The reason for my rating of 4 stars is I evaluated these headphones in 2 different applications --5 stars for comfortable sound isolation when recording an instrument in a noisy environment

I work in a noisy environment and the cheap ones work better for isolation.

The point is that these headphones have way, way better sound quality *in a noisy environment* than the alternatives.
