Modern smartphones offer clear, loud sound, but you still can’t beat a real speaker if you want your tunes to sound crisp and rich.

The only problem? Decent-sized Bluetooth speakers can be bulky, which tends to be a problem when you’re on the road or just move around a lot. That said, the Ultra Slim Bluetooth speaker from CB3 Audio offers a great compromise between portability and good sound quality.

Normally going for $35 (and, until recently, for $50), the CB3 Ultra Slim is made of aluminum, which makes it sturdy, but light. Sound quality should be great, whether you use the speaker at a party, to watch a movie, or just to lighten up the mood in the office.

This 12W speaker is definitely on the high end of the portability scale – it’s just two inches thick and weighs 1.2 pounds. Battery life is rated at 8 hours of playback on a single charge.
