Summary: Wireless Headphones
Comment: Pros: Very comfortable for extended listening. Excellent to outstanding sound quality. Excellent operation, when in same area of transmitter. Spare battery, so a charged one is always ready. Excellent product support.
Cons: Rating of 100 - 300 ft reception (one important consideration in purchase) may be possible; however, in my situation it isn't there. With the transmitter located in my den (lower level) clipping occurs in the upper rooms less than 35 - 50 ft away. Reception is problematic, also, outdoors - again, less than 50 feet from the transmitter. Reception depends largely on your homes construction, obstacles between the transmitter and headphones, other devices operating on the same frequency - so, wearing these boys while mowing the lawn just isn't going to be a pleasant experience.
Construction is adequate, if the phones are handled somewhat carefully. The area where the ear pieces are attached and allow them to swivel is the weak link. This area is really small for the task and one broke from the simple act of putting them on and taking them off. That's why I can comment on the company's product support, they replaced them sans any charge.
Price. Fairly high, especially if the range is a primary factor. In my case, only able to use these phones while in the same area as the transmitter, I probably could have made a cheaper choice and received comparable results.
Customer Rating: Summary: Not perfect but way better than many reviews!
Comment: Given the wide range of user review scores I was really anxious to see how well this product performed. I was pleasantly surprised by the sound quality for wireless headphones. When you are in the same room there is no static and usually in close by rooms there is very little either. But the further you go the more you get static that sounds like someone saying "shhhh" which is not too annoying.
I made sure that I plugged the power supply into a good surge suppressor with EMI and RFI filtering and have found no interferance from other sources at all.
So far I mostly have used the headphones for listening to my PolkAudio XM component receiver which requires a south facing window for the antenna. What a great combo! Great sounding XM anywhere in the house.
Like so many reviewers have said, these headphones are to be treated carefully due to their lightweight plastic construction. And the over the ear cups are a bit small but serve to hold the phones on very securely and still comfortably. Overall, I am (so far) very pleased with this purchase.
Customer Rating: Summary: Good enough to buy another!
Comment: I bought my first pair of these Sennheiser headphones so that I could watch HiDef/DVD in bed while my wife went to sleep. It's not my first experience with wireless, but the best to date.
Good enough that I've ordered a second pair for use in another room.
And it's actually my third set because the first pair I bought was a gift for someone who allowed me to try them out for a few days. That was enough to convince me.
I've previously used other Sennheiser professional gear. In some cases in the past I found the sound satisfying but the ergonomics less so, i.e. an earlier set of noise suppressors worked wonderfully but were awkward to carry on a plane. And I've tried a variety of other wireless headphones of assorted major brands. These are the best to date. No they don't quite measure up to wired very high end headsets, but they're pretty darned good. Signal carries from one room of a largish house to another with very few artifacts, also much superior to other wireless phones tried.
I can't explain people who cite almost immediate failure. They are well made.
