Features

Enjoy a wireless surround-sound setup with the black Bluetooth Boombox Buddy System Speaker Set from SHARKK. Equipped with both Bluetooth 4.0 and NFC technology, this dual speaker package can receive and play music from any compatible device up to 30' away. For NFC pairing, tap any NFC-enabled device to the top of one of the speakers to connect; once paired, you can connect the two speakers together and you're ready to go. Additionally, each speaker in the Boombox Buddy System features a 3.5mm port, so you can connect to an external media device or compatible speaker via the included AUX cables.

In addition to playing music, the SHARKK Boombox Buddy System enables you to make and receive phone calls via the built-in microphone. Its thermal sensor automatically activates the LED button backlighting when heat from a human hand is detected. Additionally, each speaker has a rechargeable lithium battery that lasts up to 18 hours on a full charge.

Buddy System

The SHARKK Bluetooth Boombox Buddy System takes a portable speaker and multiplies it by two. With it you can easily set up a simple yet powerful stereo surround-sound music experience, without the hassle of having to deal with wires. Additionally, the two speakers can function independently, with each providing full stereo sound.

Bluetooth v. 4.0 and NFC

The SHARKK Bluetooth Boombox Buddy System utilizes Bluetooth technology for a strong yet energy efficient connection. Just a couple of button presses and you can connect your Bluetooth device to the first speaker. Or you can use the NFC chip in your phone for an even simpler setup. Just turn on NFC in your phone and tap the speaker to connect.

Make and Receive Phone Calls

Thanks to built-in microphones, these speakers enable you to make and receive phone calls. Additionally, they're compatible with Siri and S Voice, so you can send commands to your compatible smartphone.
