For some time I've noticed that I'm increasingly finding it difficult to hear the dialogue over the background music in films and after much deliberation decided to buy a pair of Sennheiser 170's after having read a number of reviews on here.
Wireless headphones appealed to me as I always found the cord on my old pair irritating. I wanted them primarily to improve hearing the sound from the TV but also for listening to music too. I would have gone for the RS180's which are open backed and are supposed to sound superior but decided that the closed back 170's were the better option so that my wife can listen normally using the TV's speakers at the same time. If the TV's speakers are playing as well I don't hear an echo unless the TV's sound is turned up.
I've only been using them for 3 days and so far I'm very pleased with my purchase. The sound is very good, they may not be for audiophiles but I'm prepared to accept that they are not the last word in HiFi for the convenience of them being wireless and for the price that I paid. I've not had any problems with interfernce with my wireless internet connection and I can now watch films at a normal volume without relying on the subtitles. I found the range to be more than adequate and have been able to go anywhere in my house except near the window of the room furthest away. The actual stand is locate behind my LCD TV and I'm able to pick up a signal in my kitchen despite there being a wall and a large American Fridge Freeze in between and I can also go outside for about 20' before they start to cut out.
It was a little disconcerting, especially when I first used them when watching tv because the sound appears to be coming from inside one's head rather than the direction of the TV, maybe open ones would be better in that resepct, but I'm getting used to that.
I'm finding the button controls okay but once they're set up I rarely need to touch them anyway.
It would be useful to me if they had the option of using them corded to as I could then use them with another TV in a different room or with my laptop. If they had this feature and they were of an audiophile quality then I would have given them 5 stars.
Overall I can recommend them and I'm hearing a lot more things than I used to when I relied on the TV's speakers.
Update : 11-4-2015 : I've since found that I can now go to the end of my garden, a distance of about 70', providing I turn my head so that the headband is aligned with the direction of the transmitter. Not particularly convenient I know but it does help to extend the range.
I got these £160 worth headphones back in 2012 for free from my grandmother as a gift. Sennheiser RS 170 are wireless headphones which came together with a base unit which serves as a transmitter and a battery charger (fully charged battery can deliver up to 24 hours play time - I tested this and my battery lasted around 22.5 hours which is pretty good as well). The headphones are made from plastic in black-silver combination. The faux-leather ear-pads fit comfortably on ears and feel luxurious. On the right ear-pad are the control buttons (which I find a little weird but you will get used to it) such as power on, volume control, bass boost button and a surround sound simulator button. Tricky part is that the power on button is between volume control buttons so I switched few times my headphones accidentally off instead of increasing volume.
The sound quality of these headphones is very good, I cannot hear any disturbing noises in the background. Occasionally the sound became less clearer when I stepped further away from the transmitter. However just for watching movies on TV and sitting back comfortably on the couch, this wireless headphone are giving a pretty decent performance.
I cannot say that these Sennheiser RS 170 are my favorite headphones. I can even find a bunch of cheaper headphones which a prefer. In the end, these are very stylish and comfortable headphones however I do not think they are worth the money.
I ended up to giving this headphones to one of my friends. I would personally not buy them.
I live in a larger than average home with every wifi entertainment/streaming gadget known to man. I watch movies and shows at high volume, and don't want to disturb the family during late hours, etc. through my surround sound. My requirements for a headset are the following:
1) ZERO impedance, static, or "murmur", or slack time in the middle of sound and screen
2) REASONABLE separation without losing sign (I think 50 ft from your TV is truly sensible)
3) PERFECT no misfortune sound and profound bass as I anticipate from a quality encompass sound framework while viewing a film.
This headset meets all 3 requisite criteria. I'm very pleased and would highly recommend this product.
