JBL Clip 4 Bluetooth speaker review: A new design and improved sound quality One of our favorite micro Bluetooth speakers is back, and it's changed (mostly) for the good. Feb. 9, 2021 9:30 a.m. PT For its first three generations, JBL's Clip micro Bluetooth speaker had a circular design. But for the fourth-gen Clip 4, JBL has moved to a more oval shape and bulked up the speaker slightly. It's a tad heavier at 0.24 kilograms (0.53 pounds) vs. 0.22 kilograms (0.49 pounds) for the Clip 3. But it does seem more durable, with a sturdier integrated carabiner "clip." It also sounds better, with more volume, clearer sound and more bass.
