Sony ULT FIELD 5 Wireless Portable Bluetooth Speaker, IP67 Waterproof, Dustproof, and Rustproof, Black

Loud and good sound quality, portable and good bluetooth connection. Being able to connect multiple devices at once and switch is underratedly helpful.

I have only used for a few hours thus far, but my initial impression is that this speaker is quite the value! Very crisp sound and impressive output. I have handled it with care, but it appears to be capable of withstanding some less than ideal conditions. I don't intend to drag it through the dirt or foresee exposure to any impact/drop potential of note, however, it is definitely not in the same category as a speaker like Die-hard or other powertool manufacturers offer. The sound quality is much more prominent, alas the "durability" is not designed for upkeep in a heavy dirt/dust/debris environment such as the 'construction-grade' products out there. The exterior would definitely be compromised with excessive exposure to dirt, but again, I did not expect to be keeping this speaker in a workshop or similar environment. I am extremely satisfied with my purchase!
