Unlike, let’s say, Apple’s AirPods, the S570’s design has a distinct advantage that allows for better isolation, so you’re not having to turn up the volume. The ergonomic in-ear design keeps it in place but in case you need extra isolation, the S570 does come with additional rubber tips. Given the size, it’s hardly noticeable in case you’re worried about the dreaded Bluetooth head piece look. You know the one.

(Editor’s note: It should be noted that the S570 is only one singular earbud and not a pair. Most smartphones, like the iPhone, only support one Bluetooth device at a time.)

The S570 also charges in under two hours and is said to last up to six hours between music playback and talk time. Others, however, have said it can last longer than the stated six hours. And with nearly 1300 reviews on Amazon, the S570 has garnered a 4.5 star rating. Not bad for a Bluetooth earbud under 20 bucks.
