Our take on the Sennheiser MM 500-X

by Dave Bar
Sennheiser

High-quality music and calls with Bluetooth convenience

Sennheiser's MM 500-X portable headphones are fantastic for enjoying your music and managing your phone calls without getting tangled up in cords. They feature built-in Bluetooth technology for a hassle-free wireless connection to compatible devices, such as many cell phones, laptop computers, tablets, and MP3 players. You can use the integrated volume, track skip, and call answer/end buttons built into the right earcup for convenient operation while your phone or music player remains safely in your pocket, purse, or backpack. The MM 500-X headphones also support the latest aptX technology — a sophisticated audio encoder that delivers true high-fidelity stereo sound wirelessly over Bluetooth with aptX-enabled sources.

Great comfort, sound, and versatility

The MM 500-X's around-the-ear design, soft padded cushions, and adjustable headband make them a comfortable companion for long listening sessions on the go. Their folding design makes for easy storage when you travel. Sennheiser's patented Duofol™ diaphragms provide detailed, crystal-clear sound. And just in case you need it, Sennheiser includes a cable plus an airline adapter for a direct wired connection in situations where Bluetooth isn't permitted, or you want to make use of in-seat entertainment and other wired sound sources.

Highlights:

  • portable, folding, around-the-ear design
  • padded, closed earcups and adjustable headband
  • Bluetooth® wireless operation with advanced aptX audio circuitry for streaming high-quality stereo sound from aptX-enabled devices
  • built-in microphone and wireless earcup controls for hands-free conversations using compatible Bluetooth cell phones

Features

Overview: The Sennheiser MM 500-X headphones are an accessory that allows you to enjoy your digital music files on your mobile phone or portable music device, including those equipped with Bluetooth technology. The MM 500-X can be used wirelessly, or in places where Bluetooth isn't available, you can plug them in and use them as wired headphones.

Bluetooth Wireless Reception/Transmission: The MM 500-X features Bluetooth v2.1 wireless reception and transmission with a built-in microphone for cable-free use with select Bluetooth enabled phones and audio devices. Supported Bluetooth profiles include A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile), HSP (HeadSet Profile), and HFP (Hands-Free Profile). The MM 500-X saves the connection profiles of the last eight devices with which it was paired; when turned on it automatically tries to connect with one of those devices.

Note: Not all Bluetooth enabled audio devices will be compatible.

apt-X: The MM 500-X headphones are equipped with apt-X, an audio coding technology that works within Bluetooth to wirelessly deliver CD-quality audio from your portable music device to the headphones. With apt-X, you can listen to your digital music files in crisp, pure, and full stereo sound. The following 3rd party devices / configurations have built-in apt-X support (as of 7/18/2012):

  • Apple Mac OS X Snow Leopard and Lion Operating Systems

Earcups: The MM 500-X features a comfortable, over-the-ear design that let you enjoy long listening sessions while on the move. The closed design helps to provide superb passive noise attenuation. The fully-adjustable headband allows you to find the perfect fit.

Controls: On the right ear-cup there are integrated controls for your connected phone or audio device. Audio controls include volume, skip forward or backward, fast forward or rewind within a song, play, and stop. Phone controls include volume, accept call, reject call, end call, redial, voice dial, and mute.

Note: All control functions must also be supported by the connected device.

Battery Pack: The MM 500-X has a removable BA 370 PX Lithium-Polymer battery pack (3.7 volts DC/1 Wh) which provides up to 10 hours playback using Bluetooth reception. A power supply with US, UK, European, and Australian plug adapters is included to charge the battery pack; charging time is approximately three hours. The headphones can also be charged using a computer's USB port.

Collapsible Design: These headphones feature a collapsible design with metal-reinforced headband to ensure portability and durability.

Cord & Adapter: The MM 500-X will also work as wired headphones, useful when Bluetooth connection is not an option. The headphones come with a 60" mini-jack cable terminated by a 3.5mm connector for a wired connection. A 3.5mm-to-1/4" adapter, and an in-flight audio adapter (dual mono 3.5mm) are included for added convenience.

Do I need to buy a docking station or something to listen to my TV? [ James  Jan 08, 2014 ]
3 answers
  • The Sennheiser MM 500-X I received from Crutchfield included both the 1/8" jack for smartphone/tablet devices and the "fat" jack commonly used for home theater equipment. The "fat" headphone jack screws onto the 1/8" jack and works well when connected to my DENON surround sound receiver. I use the 500-X headphones most often as a Bluetooth connection to my iPhone and iPad. The Bluetooth pairing was simple. If you are specifically asking if the Sennheiser MM 500-X can be connected directly to your TV, I don't know of any TV's equipped with a female headphone outlet to accept the jack. [ RJ   Jan 08, 2014 ]
  • Nope [ Arti   Jan 08, 2014 ]
  • No there is not any docking station available for wireless functionality. The only way you can listen from TV via wired connection from your TV Aux/headphone jack. [ Kinjalkumar   Jan 08, 2014 ]
