The Sennheiser RS 220 bridges the gap between wireless and wired headphones with newly enhanced DSSS [Direct Sequence Spread Spectrum] transmission technology. Able to work in crowded RF environments amongst Bluetooth, Kleer, FM/AM, TV and Wi-Fi signals, the RS 220 delivers clear, clean, robustly uncompressed audio up to 320 feet without demanding special procedures or convoluted pairing to audio sources. Easily connects via digital optical, coax or stereo RCA method into any TV you own. Transmission base doubles as a sweet headphone charger stand with 'no worries' automatic operation. The RS220 is truly unrivaled in wireless headphone performance and features amazing wire-free headphone sound quality!
What We Think:
After hearing the Sennheiser RS 220 debut at the Rocky Mountain Audio Festival in October of 2011, we knew wireless listeners would flip their lid once they got ears on the new benchmark in the industry. Finally released to the general public in early 2012, Sennheiser claims the RS 220 to be the closest approximation of the HD600/HD650 sound in a wire-free headphone and we can't say they've missed the mark. The RS220 delivers that classically smooth, warm and easy-to-enjoy tone historically expected from the Sennheiser HD650 headphones along with a supreme sense of musical ease and intelligibility not heard in other digital transmission wireless designs. With great music recordings and orchestral or symphonic soundtracks, the RS 220 offers surprisingly tight, full bass reproduction and a very dynamically exciting, quick extension into the uppermost frequencies with just a little grain detected in the mids. The background noise floor -- always problematic in many wireless cans -- is nearly non-existent in the RS 220 with less than <0.1% Total Harmonic Distortion (THD), a new spec low in wireless technology allowing dialogue and music to sound even more distinct than via built-in TV speakers. The talk/dialogue intelligibility of the critical vocal midranges remains well-focused albeit somewhat peaky depending, of course, on the caliber of original TV recording and source. But the slightly supine midrange presentation remains only a quibble given the intense engineering required to fabricate this impressive level of wireless headphone audio.
