Review on Monster Superstar S310 Portable Bluetooth Speakers - 20W True Wireless Stereo Pairing, Dynamic Sound, Waterproof Speaker, 24H Battery, Bluetooth 5.0 with Built-in Mic - Compatible with iPhone, Samsung by Valerie Perrien

This speaker has excellent sound quality for its size. The sound is directional, but that's not a problem. All you have to do is point the speaker in the direction you want the audio to sound and you're done. The sound behind the speaker is good, just not as good as in front. The sound quality is very good for a speaker of this size and the volume is sufficient when you need it. The battery life is very good and lasts a long time. I had about 16 hours with no issues before needing to recharge. Charging is easy and is done via a micro USB cable. The speaker isn't very heavy, but feels solid and well built. This allows you to take it with you wherever you go. The speaker fits in my bike's bottle cage so I can listen to the sound on the go if I want to. It also fits very well in a cup holder in a car or boat, so that's a good thing too. Overall I would buy this speaker again if I needed a second one. I have no complaints and am very happy with my purchase.
