Invisible In-Ears: This $20 Bluetooth Earbud Can Barely Be Seen

* Are these the world’s smallest earbuds?
* Nenrent’s universal fit might actually be universal compared to others
* Fully charged in under 2 hours with up to 6 hours of mixed use

Whether you prefer over-the-ear headphones, earbuds or even in-ear style headphones, one thing is clear: the future of audio is going to be wireless. So for those seeking a wireless solution for phone calls and occasional music listening, Nenrent’s incredibly tiny S570 Bluetooth Earbud is a viable option.

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.
