Deal: Sennheiser RS120 wireless headphones with charging dock are 40% off on Amazon
Not to mention that the retail box contains a very nice charging dock for which you won't have to pay extra. Although they're not compatible with Bluetooth technology, they can be used with TV and Hi-Fi Audio via lightweight radio frequency (RF) wireless function.
The RF system features a lightweight on-ear headphone that receives sound from a transmitter base when connected to an analog output of any audio source such as a TV, sound system or computer.
The Sennheiser RS120 RF wireless headphones come with AAA NiMH rechargeable batteries to provide up to 20 hours of use. The batteries are recharged by simply placing the headphones on the transmitter base (charging dock), which automatically turns itself on and off when the connected audio source is activated or disabled.
