Well made and comfortable the RS175 is a headphone that is perfect for everyday use.

It was easy to set up. I put the optical input from the TV and the analog from the headphone out on the PC. Sound quality on both is very good. The acoustic isolation from outside the ear shell is better than my noise cancelling headphones!

I can finally watch tv without disturbing my family, the sound quality is amazing. I love that you can set them to surround sound, add bass if you like and you can adjust the volume to hi and low. Watching tv is such a joy I can hear every spoken word clearly, makes watching tv fun again.

I bought these headphones a month ago and I am very pleased with them -- I'm not much of an audiophile (though I do listen to a lot of music) but the sound quality is exceptional, especially compared to the ￡20~ earphones I was using previously.

Excellent product if you don't want to run cables from your TV to your headphones. The build quality is great. The sound is good. The wireless transmitter does not decode Dolby digital, but just PCM. No complaint though as it comes with surround sound button which is good enough.

Sounds good but having trouble with optical cable and my system so not getting all that earphones are supposed to put out.

PRO: Good audio and battery life

CON: No 3.5mm to RCA cable provided; Sennheiser unaware that optical cable ports on receivers are input only; Using 3.5mm to 3.5mm phono cable means connecting into the front of the receiver which defeats the benefits of having wireless headphones

I upgraded from a 10 year old pair of 120s. No more tuning! Base boot is nice. Surround not so much. Very happy with product

Like many city dwellers, apartment living has forced a lot of compromises when it comes to my setting up a workable home theater system. The limited amount of space and the nearness of neighbours necessitates creative solutions which wireless headphones can easily solve.
