I bought this to use at work, assembling vehicles, moving every 1/2 hour. The sound is good, I'm not in a loud environment. But the volume was at 3/4 and above for less than 4 hours and the battery was drained. The thing that was frustrating is the power button location. Since I was moving it 2-4 times an hour, the habit is to grab and go. When you do, the power button is almost always hit and the unit shuts off. I had to make sure I grabbed the carabiner. If you're looking for a small personal speaker, it had good sound and should serve you well. If you are in a louder environment, you may need more power and longer battery life.

The Clip 4 sounds better, works better, and is more durable than the already-handy Clip 3. Is it the best Bluetooth speaker out there? No, and in fact, I own two speakers that easily outdo it when it comes to sound quality: the Megaboom 3 , and the wondrous Bowers & Wilkins T7.

JBL’s Clip 4 is the best ultra compact waterproof speaker worth your attention. The palm-sized gadget has a cool and versatile design, headlined by the Clip product family’s signature carabiner.
