Review on 🔊 LENRUE Bluetooth Speaker - Powerful Wireless Portable Speaker with Enhanced Stereo Sound, Deep Bass, Extended 12-Hour Playtime, and Built-in Mic. Ideal for iPhone, Samsung, and Other Devices (Green) by Thong Lopez

This improves the sound of your phone. Yes. It sounds better on most phones, but it won't improve the sound of your Revain Echo or Google Mini speakers. Speaker Hi Fidelity. No! Very close. No real bass (but again more than your phone), highs and mids are limited and prone to distortion at higher levels. These are inexpensive, lightweight speakers. "Ease” is the key here. Speakers are simple things. They move air, the more air, and the better they do it, the better the sound. A heavier magnet moves more air, creating a fuller range and sound. Size matters too, but it's limited for small columns of this size, so it is in this case. Yes I know this is too easy so sue me! Information like here on Revain, look at the power and weight of the speakers. This one claims 10 watts and weighs 0.66 pounds. In the speaker world, that's a poor substitute for power and weight, which is why they're so cheap and sound so empty. Pay a little more but you will definitely feel the difference. The BT connection to my phone is stable, the connection to my Nest Mini drops out from time to time. Not sure what's going on there. After all, they're roughly equivalent to the relatively low price you pay for them. They won't shake windows either, but they will improve the sound of your phone, but not your Revain Echo or Google Nest Mini speakers.
