The treble is crisp and clear and better than all the other headphones I possessed

I like to listen to music without disturbing my family. I was impressed by the low price.The headphone has a great sound quality. The treble is crisp and clear and better than all the other headphones I possessed. It has a deep base when listening to jazz music. (ex ipanema cd) Amazing, I love it. Overall I am very pleased with the purchase and also with the prompt shipment by Adorama.

Works well

I use this headset for legal transcription. It helps reduce the noise around me and the sound is very clear and adjustable, but after a couple of hours it gets very heavy.
