QFX SoundTheory E-7 Portable Wireless Bluetooth Speaker

A leather carrying strap, sturdy housing, and rechargeable battery all help this Bluetooth speaker keep the music going outdoors or on the go.

Wire-Free Audio

Soundtrack a party on the deck with tunes from the laptop in the living room, or listen to a podcast stored on a phone stashed in your backpack.The SoundTheory’s Bluetooth and NFC technologies complement its portable design by enabling it to stream audio from other devices without any wires necessary.

Rich, Detailed Audio

Even though it’s smaller than a lunchbox, the SoundTheory pumps out impressive audio. The device is packed with three Elite passive-radiator driver units, which help generate powerful sound that’s still nuanced: bass comes through punchy, while treble is crisp and clear.

Stands Up to Splashes

Most portable electronics run into water eventually, whether via unexpected raindrops, splashes by a sink or the pool, or accidental drops from the bow of a ship during king-of-the-world proclamations. The SoundTheory stands up to most of these scenarios thanks to its durable housing, which is rated to resist damage from splashes.
