Learned about this speaker concept over 20 years ago and was the first thing I thought of when I needed some music for my rides. Bluetooth Kits for your helmet cost $300 or more. Glad a company was able to make it wireless. This device vibrates and essentially shakes the surface you put it on and turns it into a speaker. Obviously you cant put it on a brick or a glass of water and expect amazing sound. Something thin and pliable will work wonders for you.

The sound and overall function of these is impressive. I love that I can put it on the glass of ly French Door and hear it inside and out! Now the bad parts... I got the two pack and the the left/right channel works, but only line of site for about 10ft, so don't expect much there. Also, if you're interested in the FM radio portion, just move on and get something else... The FM radio does an auto scan, then you should be able to pick from one of the channels found in the scan, but it is almost impossible.

Good bluetooth IC, terrible otherwise. Tiny batteries. Speakers buzz and cases vibrate (not when they're supposed to). Suction cups are worthless. Sounds like severe voice coil rub. Good concept, poor execution. Unusable, don't buy. Go buy a quality mono version for the money instead.

These things are tiny, I am amazed that they were able to incorporate a battery, bluetooth + amp + resonator in such a small configuration. Bluetooth connects easily, in dual speaker mode it connects without issue, sound is not as loud as you would expect, but amazed by the sound these small units produce. The pre-mounted sticky pads sticks to all surfaces tested (melanine, stainless steel, boxes, tiles, mirrors, wood, glass, plastic, etc) which is a plus, I did not need to use the suction cup foot. I have tested the product on many different surfaces, firm boxes seems to perform the best, sound is dependent on the surface, Shower doors reproduces clear sound but edging towards harsh treble, not so much bass. Boxes has more mid frequency response and lower treble. Its a nice gimmick to show friends but I wouldn't use it for daily audio, therefore I agree with the other product reviewer, you might be better off with a portable bluetooth speaker.

My sister-in-law really loved getting this for Christmas kind of made my sister jealous but she's going to be able to use them too so she's not that mad so it was a hit with both my sister and the gift recipient my sister-in-law

I bought the pair and while one of the speakers works really well, the other has a constant muffled noise like a torn membrane. 5/10

Sound quality I would have to buy two at the same time in order for it to be loud. I didn't care about the color or size. Good value.

Me gusto mucho se escucha muy bien para lo pequeño que es
