I come across a lot of different Bluetooth speakers in my line of work. It seems like every time I'm on set, there's a new Bluetooth speaker to play around with. By far the best sounding one in my opinion is the Bose SoundLink Mini Speaker II. A bit of a surprise too, since this speaker is smaller than most that I've seen brought onto set. But size doesn't matter much here. The SoundLink Mini II is capable of blasting lots of sound without distortion. This is an important factor since many Bluetooth speakers claim to be able to get very loud, but at what cost? At the cost of sound quality? If so, then what's the point if it all sounds loud but it sounds terrible?
The SoundLink Mini II is loud and clear with Bose signature bass-heavy EQ. It actually sounds very full in a variety of songs I've tested with it. The only downside really is that this speaker costs $179. Other speakers that are just slightly worse than this cost less, but for the best of the best, I think this is the one.
Tell me how wrong I am in the comments!
