Review on DOSS E-go II Bluetooth Speaker: 12W Superior Sound, IPX6 Waterproof, 12H Playtime - Black by Tim Larsen

I gave this speaker 5 stars for size, sound and price. Yes, there are better sounding Bluetooth speakers out there, but for the reasons above, including portability, you can't go wrong with this speaker. Sounds great, loud and has a pretty good base, but it won't blow your mind. But then again, this is a fairly small speaker, so I'm not expecting the impossible. So far the battery life is excellent. Not sure how long the battery will last on a single charge but I used it for a 12 hour shift at work, it lasted most of the shift and it still has 12 hours at the end is working. Also note that I had the volume down by 50%. The higher the volume, the more the battery discharges. It looks like it has two speakers in the front and one speaker in the back for the base, which could be a passive speaker. If you're looking for a portable bluetooth speaker with good build quality, good sound and can live with items, you won't be disappointed. However, if a deep base is most important to you, you should look elsewhere. DOSS probably even sells larger models with a better base.
