AmpMe is extending the reach of its portable sound system with the addition of support for Bluetooth speakers. Users can now sync music from YouTube and SoundCloud’s apps with any supported speaker. This comes after the company’s app has been downloaded more than 3 million times.

Launched in 2014, AmpMe wants to be “the way we experience music in an impromptu social setting.” The idea is that instead of purchasing expensive sound systems from Bose or Bang & Olufsen, or even using Sonos speakers, you can pair multiple mobile devices to play the same tune in a manner that sounds uniform. Previously, if you wanted to try something like this, you had to press the play button on each device simultaneously — definitely not as easy as it sounds.

But what happens in a social setting if someone brings Bluetooth speakers? AmpMe believes its updated app will solve this. Each smartphone pairs with a speaker, and you’ll be able to control them all through a “host” app — the device that controls the music. There’s no limit to how many devices or speakers can be connected.

“Launching the ability to sync any type of Bluetooth speaker together is the most democratizing step we’ve taken in our journey to build the world’s most portable, high-quality sound system,” said company chief executive Martin-Luc Archambault. “We started with mobile devices like phones and tablets, so expanding the capability to any Bluetooth setup is the next frontier. We’re enabling music listening in a social manner and style that’s never been achieved before.”

Currently, the service only supports the music you have stored locally, along with YouTube and SoundCloud. However, Archambault said that he’s working on adding “two big sources” in the next three months and hopes to have 20 sources in the next couple of years.

This announcement comes as services, such as Tempow, are helping you find more uses for Bluetooth speakers. The new feature also leverages funds AmpMe raised back in May.
