The JBL Go 4 is our expert editors' pick for best sounding micro Bluetooth speaker. For such a tiny speaker -- it literally fits in a pocket -- the JBL Go 4 sounds surprisingly good, though it has its limitations (something this small can only produce so much bass and sound). The speaker is rated for seven hours of playtime at moderate volume levels. Plus, it's IP67 waterproof and dustproof, so your giftee can take their tunes to their next picnic or backyard hang.
The Go 4 is available in nine colors, so you can pick the one that best fits their style, too.
