Summary: These are great headphones. The bass and surround is pretty good. They are built well and fit my head well. The fact that they are wireless makes it great to walk around the house with out sound interruption.
Pros: Wireless feature and great sound.
Cons: The batteries could be better. if you leave the phones off the charger over night they will be drained the next day. The buttons on the side take getting used to. its not obvious by touch which buttons are the volume vs. the surround and bass.
Summary: These are enjoyable headphones as the surround really envelopes and clarity shines. Overall sound lacks a little richness, highs are overpowering. Nice punchy bass, not too much. After 1.5 to 2 hours they are fatiguing as most wireless headsets are. They are very light weight and comfortable. Having trouble with range in my house. It disconnects at 25 to 30 feet. Great for music or movies and even iphone.
Excerpt: After wasting money on TV Ears headphones, and doing A LOT of research on numerous websites before spending money on these headphones, I chose these Sennheiser headphones and have not regretted it at all. The headphones are comfy on your head and the sound is crystal clear. I bought these primarily for watching late night tv while my husband is busy snoring. The headphones drown out all external noise and as stated before, the audio is crystal clear.
