For $10, you get more than you paid for. I tested these speakers and they definitely passed the test. I'm a courier and whether I'm driving 6-7 hours in my car or on my e-bike, this speaker will last a full shift without the need for an additional external power supply. The sound quality is ridiculous for the price. At this price point, you'd expect some downsides, as cheap devices tend to cut corners. I don't think that applies to Crasher Micro. The sound is crystal clear and there's even a passive subwoofer. I can hear every word of the song, even on a busy street, and it's not muffled or of poor quality. Aside from the music, the GPS is usually active during my shifts and I can hear every direction from Google Maps. I think the only real downside is that it doesn't have volume controls. The volume is controlled by your phone. Ideally, it should be at or near maximum for optimal volume and sound quality. Other than that, I can't recommend it highly enough. To be honest I don't quite understand how this product is available for less than $10.
