The RS220 comes priced at around $600, just about $250-$275 more than the wired HD600. If they can indeed pull off the high end sound of their wired brothers, the RS220 may be this year’s headphone game changer. The Sennheiser RS 220 has set a new bar for delivery of high fidelity audio across the wireless spectrum. No longer do we need to remain wired to enjoy the brilliance of well recorded music. The Sennheiser engineers chose DSSS (Direct Sequenced Spread Spectrum) wireless and lossless technology for the RS 220 – a new technology to the Sennheiser wireless line that provides more power the headphones. The drawback of DSSS is the shortening of listen time in the internal battery. At full power, the RS 220 should give the listener a good six to eight hours of listening time. Charging the Sennheiser RS 220 is as easy as setting the headphones down on the base station.
That base station also houses a variety of connectors that allow for the headphones to speak to your stereo hardware. Choose from analog and digital connections on the base, though the RS 220 cannot decode Dolby or DTS signals – limiting you to PCM output on your stereo to pass a digital signal. You will find volume as well as left/right balance controls on the cups of the RS 220. The control make decent sense, though, we would have preferred a better button layout. One note on the Sennheiser RS 220: the volume limit on the cans. When the max is reached wearers will hear and audible beep. Range on the wireless headphones is 300 feet. Overall the sound quality remained on point – competing as expected with the wired Sennheiser HD 600 which the RS 220 is loosely based on.
Out of the box and fully charged, the RS 220 frees the listener from the lock down of a cable pull. It is a dream to walk around the home or office with the RS220 while still holding a clear and natural sound. While slightly heavier in weight than most headphones, they are not fatiguing nor limiting. Those looking for a wireless audiophile-grade headphone should very much consider the Sennheiser RS 220. They price in at $599 and will free you to walk around and carry on with your life while experiencing some of the best sound available in wireless headphones today.
