The Sennheiser RS 170 Headphones, feature a completely wireless system to bring you extremely portable high quality headphones, don’t let the wireless fool you though, the Sennheiser RS 170 Headphones still deliver the highest possible quality by utilising Kleer’s uncompressed digital wireless audio transmission. This effectively enables you to be up to 80 metres away from the transmitter (whilst still in line of sight) and still receive the same high quality audio that we’ve come to know and love from Sennheiser products.
The RS 170′s are feature a black and silver design. The Sennheiser logo can be seen a few times whilst taking a look around the headphones.
With the RS 170′s being full size headphones, you’d expect them to be rather heavy and intrusive, but they are actually quite light and don’t take up too much room at all thanks to the desktop transmitter that both charges and allows you to dock the headphones.
You’ll notice on the right headphone that there are a few different buttons. These allow you to turn the volume up / down, power on the headphones and turn the bass / surround settings off.
The Sennheiser RS 170 Headphones feature leatherette earpads and headband cushions to provide outstanding comfort whilst in use. The circumaural design also helps in preventing sound leakage.
The desktop transmitter’s design is completely black and again features the Sennheiser logo a few times.
The rear of the transmitter is where all of your cables and plugs go, as you can see there are only two places to put cables; the audio-in and power port. In between both of these, we have the attenuator, which basically acts as the opposite to an amplifier allowing you to reduce the power or amplitude of a signal (the music) without distorting the waveform.
The front of the transmitter features the Sennheiser logo at the top. The bottom has the power button, surround button and bass button, much like the buttons we saw on the headphones.
Located just above these is the charge indicator, which glows red whilst the headphones are charging and green when they’re charged. A full charge will take about 16 hours so it’s best to leave them in overnight.
As you can see on the top of the transmitter, we have the dock for the headphones.
Sennheiser have bundled in quite a few accessories so that you can enjoy your music from any device and wherever you may be.
These include UK, US, EU and AU wall adapters, detachable audio cable, RCA cable, 3.5 / 6.3mm adapter, 2 AAA NiMH rechargeable batteries (for headphones), cable dresser, cable binder and instruction manuals.
