Henniu Bone Conduction Speakers, Wireless Speakers 1 Pack Humbird Speaker Wirelessly BT Speaker Mini Portable Loud Stereo Sound Built-in Mic Sound Box(Silver-1pcs)

This little speaker is a great simple addition to make any project more dynamic. Use the supplied usb cable (other charger type cables may not work) plug into your computer and it pops up like a thumb drive - erase the included song and drop your song into the drive and you’re done. It has 3 volume settings on the back and I used The lowest setting for my canvas picture project. There is also a tiny on/off switch on the bottom of the device. As far as the song - there are YouTube to MP3 converters on the web - and then you might have to google a compressor to compress the song down to a smaller file size. My songs were too large (6 mbs) and wouldn’t play - I compressed them down to less than 4mbs.

The sound quality is different with everything you put it on, do some experiments to see what works best, I found popcorn tins worked best. The battery life isn't great but it will get you through a couple hours of listening. It's small so you can take it anywhere.

Used it until the battery died. It did work great until then but it would not take a charge after that. I did get a full refund from the seller.

The sound quality is great and depending on the item you're conducting the sound through it really amplifies. Figuring out how to make the bottom stick to anything is difficult and makes me wonder if a regular speaker would be just as good. But a really unique idea as I love gadgets.

I put it on a huge metal sheet outside, which is so loud, that I got a noise complaint. It's so fun!

Great little product, I would suggest using the lanyard to make it a little easier to keep up with :)

I am having too much fun putting this on everything to see what sounds the best.

Good sound but the battery only lasts for like 20-30 mins
