Review: Great product, great price! - Works awesome.
Review: Works as long as it's stationary - I use this for my PS Vita, and it does work through A2DP. Be careful if you're using this on a laptop. If your laptop does not support line-in, it won't work! I thought it was defective on my Lenovo P15, but it turns out I don't have line-in. Do pay attention to that. Works fine on PC with line-in support. As long as you keep this stationary, the sound is fine. I would not recommend this for a car.

### ⭐⭐⭐⭐⭐ Great product, great price!
*by S***Y on April 26, 2026*

Works awesome.

### ⭐⭐⭐⭐⭐ Works as long as it's stationary
*by M***Y on February 25, 2025*

I use this for my PS Vita, and it does work through A2DP. Be careful if you're using this on a laptop. If your laptop does not support line-in, it won't work! I thought it was defective on my Lenovo P15, but it turns out I don't have line-in. Do pay attention to that. Works fine on PC with line-in support. As long as you keep this stationary, the sound is fine. I would not recommend this for a car.

### ⭐⭐⭐⭐ Cool little blue tooth Audio for old speakers & systems.
*by A***W on April 16, 2026*

Hooked this to the spare old PC desktop speakers with subwoofer, in a typical 9’x10’ room and the connection was very good, paired with iPhone, don’t have an Android device to be tested with. Audio is lossless, could be it’s within a small room, did not try walking away or outdoor use. Didn’t stay long enough to see how long the built-in battery last, but it’s fairly easy enough with a Micro USB port for charging (not Type-C). Keeping it. Will follow with an update in a few months.
