Portable BT 4.0 speaker gadget review

Portable Outdoor Speaker

When we received and un-boxed the delivery package sent by 1ByOne, we were quite surprised about this wireless Bluetooth speaker. The portable speaker is even smaller than we thought it would be by looking on the product images. The most surprising fact about this small form factor is the brilliant and clear sound that comes out of this speaker.

You love to listen music while having a shower?

This gadget makes it possible! It comes with a rugged silicone outer shell and a silver clip to hang it into the shower. The wireless Bluetooth 4.0 technology with enhanced bass lets you play your music from any BT compatible device within a range up to 10 meters. The IPX6 waterproof feature protects the device against water from outside, although we did not test it in a bath tube and don’t recommend to put it directly into heavy water.
