Summary: I am hard of hearing and i purchased wireless headphones to help me hear speech on my TV. These headphones are the second pair I have purcheaed, the first ones were the 120, they worked well enough but brok in 6 months. I went ahead and purchased the 170's as I did not want to repeat the problem I had with the 120's. Though the 170's sound much better, they still have the same design weakness as the 120's (cheap plastic connectors holding the headphones on the headband).
Pros: Excellent sound quality these makes it easy to understand recorded voices, ease of use, very comfortable fit, excellent range.
Cons: Very cheap plastic construction. Easy to snap off (break) the earphone when adjusting. Awkward placement of controls on the earpiece, you have to remove headphones completely to make adjustments to the sound output.
Summary: I have been using these for a little over a year now. I bought them to replace my 900 mhz headset, which I was very happy with for many years. I agree with all the comments on having to take headset off to press buttons. I find the surrond sound button ineffective and the bass button doesnt do a whole lot. I use these for movie listening late at night. I find when it comes to action movies the speakers get distorted at a medium volume level..
Pros: Comfort, charging, distance
Cons: speaker quality, operating buttons while wearing
Excerpt: I use these when I'm on the rowing machine and they perfome well 90% of the time. They block out the sound of the rower effectively enough and provide good, clear stereo sound. I hear a few pops and hisses every time I use them but it usually stops after a few seconds, and is very intermittant. Once when I went into the "surround" mode the sound from the right ear cup dropped to almost nothing. This stopped when I switched back to normal mode.
Pros: Good interface, Good price BH, Good sound, Lightweight
Cons: "leatherette" material, Some hissing and popping
Excerpt: First of all, the sound is great. This is a good unit for a single user. However, getting 2 sets to synch at the same time is often difficult. Additionally, the headset becomes uncomfortable and hot when in prolonged use. The controls on the earpiece are difficult and cumbersome to use without taking the unit off the ears.
Summary: I'm using these to listen to our TV; they are connected to the headphone out.
I bought them to replace my failed Sony MDR-RF4000K, but I'm not too sure if it was worth it. Compared to Sony, I can't really say there is *any* improvement, maybe only when playing GT5 - Sony had a very weird problem when sound was "travelling" between ears, possibly because it was dolby-encoded? Not sure, but these don't seem to have the same problem.
Pros: Sound fairly decent
Cons: Cut out when input volume is low; cups are too shallow for my ears, manual switch on
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.
