With Bluetooth speakers becoming more the norm, contending with cables can feel like a hassle. Fortunately, the Pebble keeps the wires few and tidy. The two speakers are hardwired together, so all you need to do is plug the USB cord into one of your PC ports, and the 3.5mm input into your headphone jack. Each of these cables is attached to the back of the right speaker, so you don’t need to worry about losing them.
Pebble delivers surprisingly rich, immersive audio. Usb-powered 2.0 speakers tend to suffer in sound quality compared to their Ac-powered counterparts, but that wasn’t the case here. Highs were crisp and clear, and the bass had plenty of presence. The audio overall had depth and detail no matter what type of music I ran through the speakers. The tipping point for speakers this size is usually at higher volumes, where distortion becomes an issue. But even when playing bottom-heavy genres like dub or dance music, the Pebble retained crystal clarity at high volume. Decent sound in sub-$30 stereo speakers is as rare as gold. The Pebble sets a new bar with its well-above-average audio. It’s not audiophile quality—nothing at this price point is—but it’s fuller and more balanced than you find in PC speakers that cost twice as much. The Pebble offers an inexpensive audio upgrade that’s tough to resist.
