Bone Conduction Speaker, True Wireless Speakers Mini Portable Stereo Sound Creative Speaker Compatible with iPhone, iPad, Samsung, Tablets and More Box

I absolutely love this little guy! The resonance works best on cardboard, but it is a lot of fun to try and find what other surfaces resonate as well. I bought this to stick to the inside of my bus remodel, which is basically a tin can right now. It isn't as loud as I would hope, but works well for the size of the space. on most surfaces, this is about as loud as my phone speaker. on a cardboard box, this is significantly loud. If you plan to use it to dissect tone qualities in your audio, pass. but if you are using it to listen to music, audiobooks, etc. like most people, this is great. Only major downside is that the suction cups aren't great (go figure). I'll have to readjust the speaker occasionally as it shakes loose of the suction grip and moves around. I would not trust suctioning this to a wall or ceiling. The sticky pad might work, but I want this to be more portable, so haven't tried it

I liked the idea of this. I'm not super impressed. The sound quality has to do with the stability of the surface and the volume has to do with the vibrations that the surface can provide. I put it on my window and it was ok for volume. I put it on a paper plate and it was really loud, but lots of noise from the vibrations on the plate. The idea is cool and maybe they have a better quality speaker that uses the same technology, but this one was just meh.

Truly amazed at what this little thing can do. I'm a musician, and also have an enormous old school stereo at home. So when I'm on the road, I'm always missing my big sound. This doesn't deliver anything near the huge sound of a home stereo, but it makes up for it in form. I gave my first away as a gift, to my also-stereo-loving father, and it took over the party. We spent hours finding different places to test it out. Our favorites were a sliding glass door, and a car door. I bought myself one, too, and have used it vacations and business trips. Not quite loud enough for beach use, since you're not bringing anything particularly big enough for it to attach to at the beach, but works great in hotel rooms (try the window).

I definitely like the sound when attached to the right surface. Does come loose depending on what you put it on. Looks cool and works well. It’s portable and good sized so can take it to work and put it pretty much anywhere

This is a terrible product. Will not use. The sound was awful.

I got this because I thought it looked interesting and it is so awesome. Literally can stick it on most hard surfaces and it will make a speaker. The quality isnt like super crisp but I would say it is more like phone speaker quality. However it is much louder than a phone. I was surprised that my wall Of my room (drywall) was able to sound so good. It is very small and portable which is also very convenient. You would not expect a tiny device to sound so powerful.

Poor sound and battery life. Looks cool and connects easily.

I use it to test acoustic surfaces like guitars and such. It performs an amazing job as a sound piston. Cardboard boxes, tables, the refrigerator come to life quite loud. It exceeded my expectations as a sound/bone conduction speaker. Comes with magnets, suction cups or stick on for attachment to surfaces.
