An excellent... tho as sold flawed... product
The good:
The Sennheiser RS160 wireless headphone are light weight and exceptionally comfortable to wear for long periods of time. Its over the ear design nicely blocks out a fair amount of external noise. The quality of the digitally transmitted sound is excellent. But because the sound is natural, not altered, those who demand thumping bass may be disappointed. TV viewers, classical music and jazz listeners, will love it. The run time on its (inexpensive and genetically-replaceable) two AAA NiMH batteries powering it is excellent... many hours. The small "puck-shaped" transmitter can be powered off AA batteries and so used portably, making any portable device that has a standard 1/8 (3.5 mm) headphone jack a source of wireless sound for the headphones.
The not GREAT, but acceptable:
There is a minor futzy-ness involved when you turn on the headphones to get them to pair to the transmitter. Which can involve also turning on the transmitter itself. But this is not a big deal.
Charging the batteries through the connector on the headphones is very slightly awkward, but you can always use an external NiMH charger or in a pinch just pop in AA alkaline batteries.
The bad:
In a burst truly stupid and incompetent user interface design, Sennheiser put the on/off/put-on-hold (also "pair phones") button RIGHT BETWEEN the volume up and volume down button, making it essentially IMPOSSIBLE to adjust the volume of these headphones while wearing them without, in the course of fumbling with the up and down buttons, hitting the on/off button and muting or turning off the headphones. A design that should have been obvious as problematic at the very earliest stages of design of this product, and UTTERLY rejected as an obvious mistake.
I OTHERWISE liked these headphones SO very much... I own about six pairs which are installed at various residences of mine and friends... AND the fact is I am a life-long electronics tinkerer... that I personally fixed this flaw on all of the headphones I own, taking them apart, making a board with a little push button on it, removing the stock power on/off switch and the plate that actuates it, wiring my substitute switch to the circuit board, and mounting my substitute switch off to the side where one does not hit it accidentally when adjusting volume.
UNFORTUNATELY, the ordinary end purchaser and user of this device is not likely to have the skills and equipment and time to do this. Indeed, I found it took much of my skill in working on circuit boards to make the modification, lest solder pads on the circuit board get torn off when removing the surface-mount-soldered power on/off push push-button from that tiny crowded circuit board.
So IF you can live with the poor positioning of the power on/off button... if in your normal use you very seldom need to make adjustments of the volume level after setting up the headphones to start listening... these are SUPERB headphones, and if you look for a good deal on them here on eBay, an OUTSTANDING value. But... if the problem I described above is a stopper for you... and it will be for many... you might want to look at other brands or models of wireless headphone.
Note that these WIRELESS but NOT BLUETOOTH !!! And with the rise of bluetooth headphones that don't need a separate powered transmitter (the transmitter is integral to your cell phone, lap top, etc.) they are becoming for many an "obsolete technology". But not for me and those still using quality high-fidelity old receivers at home, or who find existing bluetooth sound quality too low, and cost of the few bluetooth headphones that have half decent quality too high at this time (April 2018) that I am writing this review. Things likely will continue to change in those respects, tho.
These headphones make GREAT TV headphones used with TVs that have or are provided with via an adaptor a line level or headphone audio output.
