Summary: Instructions manual is on CD supplied, but you can also download it previously to receipt of headphones from Crutchfield on "Download owner's manual" or from Sennheiser website. Sound is great for wireless phones, works good around the house with minimal or no notable distortion. It takes a while to charge it the first time (+24 hours) but subsequent charges take less time (less than 8 hours). Lightweight headphones so you will not feel then. Bass and surround are great.
Summary: The first thing that I do when I get a new product is read the operation manual. This Sennheiser product doesn't have one. They include a CD instead. My PC wouldn't read the CD. Apparently this has something to do with auto start being disabled. I have never had this problem before. Manual starting of a DVD/CD is usually just a click. I found the manual online at Sennheiser's website.
Excerpt: I purchased these several months ago due to a slight hearing loss which meant I had to have the volume up very loud to hear people speaking on TV and movies. However this meant the sound effects were too loud for everybody. These have solved this though the distinct separation of external sound interference. I would highly recommend these.
Summary: After lots of research I went for these and I have no regrets, they are so comfortable I can wear them for hours. The sound is excellent with enhanced bass/surround options aswell as controls on the headphones. The transmitter/charging dock is great. Also comes with lots of accersories in the box such as 1/4 jack and cables to get to tv or hi fi system. Really pleased overall.
Pros: easy to wear, 3d sound., none that I can see
Summary: These are terrific. You can turn the volume down on the tv and it doesn't affect the sound what so ever. If you have problems hearing subtle conversations on the tv these allow you to hear everything clearly. Highly recommend!
Summary: We love our Sennheiser HDR170 Wireless headphones. I bought the headphones with the base as a gift, for my partner, and bought a second set of headphones for myself. We find the sound quality to be fantastic, the dialogue is much clearer, and we hear sounds in well loved music dvd's that we hadn't heard previously. Not much to dislike - we love listening to music and movies with our Sennheiser Headphones!
Summary: My rating: 3/5 Would you recommend to a friend: No. A lot of reviews said this was a great product, so I bought it. I would not rate it above "okay". Cons: - To me, the product seems very frail / fragile. - You have to press a button to switch between "single mode" (using only one headset) and "multi mode" (using multiple headsets). This seems like a very obsolete approach to me: it should always be multi mode.
