The short answer

Ranked #3 in Best Portable Bluetooth Speakers Under $100

JBL Clip 5

4.3

$79.95as of Jun 7

The JBL Clip 5 is the best ultra-portable clip-on speaker under $100, with a built-in carabiner that makes it the easiest speaker here to take anywhere. It adds a customizable 5-band EQ, IP67 durability, Bluetooth 5.3 and around 12 hours of battery, all in a package that weighs almost nothing. It won't fill a room or deliver deep bass, but as a personal, attach-to-anything speaker it's the class leader.

Strengths

— Genuinely useful built-in carabiner clips it to a bag, belt loop or branch
— Decent clarity and customizable 5-band EQ via the JBL Portable app
— IP67 waterproof and dustproof despite its tiny size

Watch-outs

— Sound gets crowded if you push the volume too high
— Limited bass and room-filling power given its size
— No speakerphone or aux input

Higher ratedRanked #2 in Best Portable Bluetooth Speakers Under $100

Ultimate Ears WONDERBOOM 4

4.4

$69.99as of Jun 7

The Ultimate Ears WONDERBOOM 4 is the most rugged, take-anywhere speaker under $100, combining an IP67 rating with a floating, drop-proof body and omnidirectional 360-degree sound. It's punchy for its size and now charges over USB-C, making it the ideal companion for a hike, pool or shower. The downsides are that it's only a small step up from the Wonderboom 3 and still lacks app support, but as a grab-and-go durable speaker it's hard to beat.

Strengths

— Genuinely durable: IP67 dust- and waterproof rating plus a drop-proof, floating design
— Omnidirectional 360-degree sound that stays consistent no matter how it's placed
— Surprisingly punchy bass and Outdoor Boost mode for open spaces

Watch-outs

— Only a modest upgrade over the Wonderboom 3
— Still not supported by the Ultimate Ears companion app, so no EQ
— Not powerful enough to fill a large room or big backyard

How they stack up

JBL Clip 5

The JBL Clip 5 is the most portable speaker in this group thanks to its integrated carabiner, which neither the JBL Flip 6, Ultimate Ears Wonderboom 4, Sony SRS-XB100 nor Anker Soundcore 2 offers in the same clip-and-go form. It shares the IP67 durability of the Flip 6 and Wonderboom 4 but in a far smaller body, trading their fuller sound and volume for unmatched attach-anywhere convenience and JBL's customizable app EQ.

Ultimate Ears WONDERBOOM 4

The Ultimate Ears Wonderboom 4 is the durability champion of this group, matching the JBL Flip 6's IP67 rating but adding a floating, drop-proof design and omnidirectional 360-degree output the Flip 6's forward-firing drivers don't offer. It's more rugged and more pocketable than the Flip 6 but pushes less volume, and like the Sony SRS-XB100 and Anker Soundcore 2 it's aimed at personal and small-group listening rather than filling a space.
