Review: Get Big Surround Sound from Tiny Bluetooth Speakers

At the recent Consumer Electronics Show in Las Vegas, I was blown away by the sound of the tiny X2 Wireless Surround Speakers ($39.97) from Kempler & Strauss. Given the sound, I expected the speakers to be much larger and frankly, more expensive than the $40 racquetball-sized speakers. Their small, spherical shape makes them well suited to creating surround sound. They pair together via Bluetooth for wire-free listening and the battery lasts for about four hours.

They don't have Alexa integration, which is understandable at that price, but more speakers these days do indeed have Alexa. The speakers charge via a magnetic charging base or via the included travel cable and straps. The X2 speakers are sold in both silver and black.


  • Remarkable sound from separate Bluetooth speakers
  • Compact size
  • Magnetic charging base
  • Travel cable and straps
  • Silver or Black


  • No Alexa integration

Final Verdict

Try the X2 Wireless Surround Speakers from Kempler & Strauss and prepare to be surprised.
