No need for wires

Most music lovers have enjoyed their favorite tunes with a portable device and a pair of headphones. But if you've never listened wirelessly with Bluetooth headphones, we highly recommend giving it a try. The AKG K845 BT headphones are a great way to experience the freedom of wireless listening, especially when you're on the go. They offer a strong combination of sound quality, comfort, and Bluetooth compatibility for wireless listening with your smartphone or a computer.

Built-in music and call controls

Just because there's no cable, doesn't mean you can't maintain control of your music and phone calls. Play and pause songs and adjust the volume using the headphone's earcup controls. The tiny microphone built into the headphones lets you make phone calls. Just press the answer button to talk without ever taking your phone out of your pocket.

Following in the AKG tradition

The K845 BT's design is based on their popular K550 headphones, well-known for their spacious sound and sparkling high-frequency detail. The K845 BTs maintain the clarity and wide soundstage of the older model, while adding more low-frequency punch. The closed-back earcups are smaller than the K550's, making these more portable while maintaining excellent noise isolation, so all those musical details shine through. The design is also extremely comfortable, with large protein leather earpads and a lightweight, padded headband.

Yep, there's a headphone cable in the box, too

Charge up the K845 BT's built-in battery using the supplied USB cable and your computer or AC adapter. You'll enjoy up to eight hours of wireless listening and conversation. But what if your battery runs down? Simply plug in the included miniplug headphone cable to keep listening in passive mode for as long as you like. A wired connection also allows you to plug these headphones into a quality headphone amplifier for even better sound quality.

Features

Overview: The AKG K845 BT over-ear Bluetooth headphones have a closed-back design to provide natural noise-isolating qualities. They can connect wirelessly to most Bluetooth-enabled devices for audio playback and phone calls. The K845 BTs are part of AKG's On the Go series, so they are built for portability, however, they also work well in the quiet setting of your home.

Bluetooth: The headphones' Bluetooth technology offers wireless connectivity to a wide range of smartphones and devices. NFC (Near-Field Communications) connectivity allows you to connect instantly to select Android smartphones by simply touching the device to the right earcup. The K845 BT has easily-accessible controls on the right earcup for playing audio and answering phone calls.

Drivers: The K845 BT's exceptional studio-quality sound starts with specially-selected 50mm drivers and a closed-back design, which deliver precision sound with superior acoustic dampening and enhanced bass response.

Battery: The headphones are powered by a built-in Lithium-polymer rechargeable battery (3.7 volts, 320 mAh). The supplied USB charging cable lets you charge the headphones at any USB port. A 3-hour charge provides up to approximately 8 hours of listening time.

Design: The headphones' unique 2D Axis folding mechanism allows you to fold them flat for storage or to pack in a suitcase or briefcase. The protein leather ear cushions provide extreme comfort for hours of listening.

Cables: The K845 BTs come with a 48" detachable straight audio cable, which allows you to listen to your music when your battery is exhausted. The cable terminates into a narrow 3.5mm stereo mini-jack plug that can be used with most smartphone cases. The 56" USB charging cable has a Type A USB on one end and a Micro USB connection on the other end.

Crutchfield Customer Review (What's this?)

  • "Coolness Factor"
  • Build Quality
  • Comfort
  • Noise Reduction
  • Sound Quality

This is something I've wanted for a while - a listening device without being encumbered by cords, but a product that fits my exercise routine and has decent sound. This product fits that bill. The sound is better on new digital recordings than old recordings that have been digitized, sometimes on those a little muddy in the bass range. Still I'm not looking for superb sound when exercising, so it works well.

Pros: works with bluetooth, comfortable, decent sound

Cons: Sound varies, depending on the nature of the original recording, as above.
