Q: I have a Denon AVR-887 receiver & Onkyo cd-player. The Denon is rated at 135 watts per channel. I like to listen to classic rock such as Led Zeppelin, The Beatles, and AC/DC at pretty high volumes. Will these headphones work well with this set-up?

A: I am using them for Zeppelin, Deep Purple' Sabbath and deicate stuff like Yes, Pink Floyd and some softer rock. I am also using it for studio mixing as well. I think you can go wrong with them. I also run them through a dedicated DAC / head phones amp. They are 150 ohms so they should run on mostly any amp.

Q: Can you use this with a MP3 player . Or is this just for home stereo or sound equipment. I want to use this for a carry cell phone or MP3 player . Let me know please .

A: These are actually 150 ohms, so it will run off your mp3. I would however strongly recommend a DAC / headphone amp. They are relatively inexpensive and will make a world of difference in the sound
