Sennheiser Wireless Headphones MM 500-X., excellent condition. NOT noise cancelling. Used for work but I’m now retired. The following details are from “Sonic Electronix”: Audiophile, Premium, Best In-Class, Sennheiser The award winning Sennheiser MM 500-X over-ear Bluetooth headphones offer you the best of both worlds: the freedom of wireless Bluetooth music and the high quality sound that Sennheiser is known for. These premium over-ear headphones don't skimp on the internals. Utilizing the latest aptX technology, an advanced audio circuit to deliver true high-fidelity sound over Bluetooth, the MM 500-X headphones don't disappoint. Sennheiser's patented Duofol™ diaphragms provide you with incredibly detailed, crystal clear sound. To go along with the convenience of Bluetooth and awesome Sennheiser sound, the MM 500-X's were carefully engineered to provide you with the ultimate in comfort during even the longest listening sessions. Premium soft padded headphone cushions and an adjustable headband ensure these headphones allow nearly any user to wear these headphones discomfort-free for hours on end. Enjoy Bluetooth Freedom with the Sennheiser MM 500-X HeadphonesBluetooth Freedom No matter how carefully you wrap and store cables, they somehow find a way to get tangled up. Headphone cables are no different, and the MM 500-X headphones were designed with Bluetooth to give you that wireless freedom. Combined with the built-in microphone, these headphones are perfect for getting lost in your music and managing your calls without getting ever tangled up in that mess of wires again. Integrated Controls for Easy UseOn-Board Controls When you're in a groove the last thing you want to do is pull out your phone to adjust the volume or skip a track. These headphones have eliminated that inconvenience by integrating volume, track and phone call controls into the right earcup to give you total direct control of your device. You'll never have dig your phone out of your pocket, purse or backpack to control your music or answer a call again. Collapsible Headphones for Easy PortabilityPortability Let's face it, as much as we would all like to never take off our headphones, there comes a time where we just have to. While the MM 500-X's are best served being listened to, Sennheiser engineered them with collapsing hinges with those non-use times in mind as well. When collapsed, these headphones are incredibly compact, making them both easy to transport and store. We can't imagine that another set of headphones offers this much sound quality and convenience for anywhere near this price, making these the best all-around, reasonably priced set of headphones we have heard yet. - Oliver Amnuayphol, Digitaltrends.com General Features Over-Ear Wireless Bluetooth Headphones Computer optimized magnet systems minimize harmonic and intermodulation distortion Connect wirelessly to any Bluetooth enabled devices for CD Like Quality with apt-X Hi-fi technology and an invisible microphone deliver superb stereo sound and clear conversations Easy headset controls in one intuitive cluster for simple switching between calls and music Luxurious Isolating Earpads provide additional silence, while offering Platinum 5 Star comfort Neodymium ferrous magnet systems ensure optimum sensitivity and an excellent dynamic response Exceptionally natural, spatial and accurate sound Direct cable option for use on airplanes, with an airline adapter included Foldable Easy-2-GO design minimizes the space needed to securely store these headphones safely in the provided travel case Rechargeable Lithium Battery for long lasting continuous usage, and can be purchased additionally for longer trips Sennheiser BA 370 PX Battery (535105) Primary Color Tone: Black Secondary Color Accent(s): Silver, Brushed Aluminum, Blue Manufacturer Part Number: 502888 Product Specifications: Supported Profiles: Bluetooth: Version 2.1 + EDR Transmission Frequency: 2.4 GHs Transmission Power: 8 dBm Advanced Audio Distribution Profile (A2DP) Audio/Video Remote Control Profile (AVRCP) Headset Profile (HSP) Hands-Free Profile (HFP) Codec: SBC, atp-X Headphones: Transducer Type: Closed, Dynamic Driver Ear Coupling: Circumaural Nominal Impedance: Active: 590 Ohms Passive 100 Ojms Total Harmonic Distortion (THD): 0.1 % Frequency response (headphones): 15 Hz - 22,000 Hz Sound Pressure Level (SPL): 107 dB Microphone: Built-In: Yes, Discreet Profile (Invisible) Pick-Up Pattern: Omni-Directional Frequency Response: 100 Hz - 10,000 Hz Battery: Type: Lithium-Polymer, Rechargeable Specs: 3.4 Volts; 250 mAH Model: BA 370 PX Talk time: 20 hours Listening time: 10 hours Charging time: 3 hours Cable length: 60 Inches (1.4 m) Weight: 6.31 Ounces (179 Grams)
