OLD LYME, CONN. — Sennheiser introduced a variety of new headphones this month in both the wired and wireless categories.
The first models in a series of wireless headphones — models RS 160, RS 170 and RS 180 — are all said to feature audio via uncompressed wireless transmission from Kleer.
The RS 180 can be used at a radius of up to 328 feet, while the RS 160 can be used up to 65 feet and the RS 170 up to 262 feet. Dynamic transducers with neodymium magnets and a distortion of 0.5 percent reproduce even the subtlest musical nuances, the company said. The frequency range is listed as 18,000Hz to 21,000Hz, with a sound pressure level of 110dB.
Other features include padded ear cups and adjustable headbands.
Suggested retail are as follows: RS 160, $259; RS 170, $329.95; and RS 180, $389.95.
The PX 210 BT portable mini headphones, equipped with Bluetooth and new Apt-X coding technology, has a transmission range of up to 33 feet and are said to weigh less than 4 ounces. The earpiece features audio controls, which can activate or deactivate the Bluetooth function, regulate the volume and navigate a playlist. The rechargeable lithium-polymer battery provides up to 12 hours of use before needing to be recharged, the company said.
Frequency response is listed at 15,000Hz to 22,000Hz. Sennheiser said its patented Duofol diaphragms almost entirely eliminate standing waves to reproduce brilliant highs and fast, tight low end with impeccable clarity.
