Looking for the best Bluetooth speaker under $100? This is the most important price point in the category, because $100 buys the #1-ranked speaker in two entire size classes — not a good budget option, the actual best. Below that headline, large speakers improve substantially and boombox/party speakers are still weak. Last updated: August 08, 2026.
The Headline: $100 Buys Two Class Leaders
The best medium speaker on this site costs $50. The EarFun UBoom L, tuned by Oluv, ranks #1 of 133 medium speakers — not #1 for the price, #1 outright, ahead of speakers costing many times more.
The best small speaker on this site also costs $50. The Tribit Stormbox Micro 2 ranks #1 of 45. Between these two, most people’s “which Bluetooth speaker should I buy” question is already answered before spending the other $50 this budget allows.
Best Overall Under $100
The best medium speaker available at any price, at $50, is the Earfun Uboom L: $50 after coupon UBOOMLWC Amazon Myearfun
Pros: Tuned by Oluv and he knocked it out of the park. The audiophile choice. Extremely neutral, possibly the best of any modern Bluetooth speaker slightly behind the Vifa Helsinki. This is the only speaker that sounds correct at every volume level. Other speakers will need a different EQ at each volume level. For maximum volume without distortion use max volume - 1 step for most songs. Oluv left another higher volume for songs that are quiet. Amazing sounding at low levels as it boosts bass and treble at low levels to account for the equal-loudness contour.
Cons: Latency is high (400ms) without turning on low latency mode (66ms) which doesn’t work when two speakers are TWS paired. Low latency mode can be turned on by pressing the Bluetooth button twice. If latency in TWS paired mode is a very important feature, like if you watch a lot of video, you may want to choose another speaker. The power button can sometimes get accidentally pressed when put in a bag. The aux input has quite a bit of latency and isn’t recommended for video use.
Setup: Try setting up the Earfun App (Android or iOS) to see if that works. If not, you’ll need to flash firmware 1.2.7 to work with the app and set with Oluv’s EQ in the Earfun app which sounds the best. The instructions say that you need a USB3 cable, but most USB2 cables work just fine, try the one included with your phone. Check the current firmware version by turning it on, then pressing the power and Bluetooth buttons at the same time. To flash, turn the speaker off then hold down the Bluetooth button while plugging in the cable. To flash on a mac, see these instructions. In TWS mode, long press the outdoor button for 2 seconds to change TWS to Party mode and back.

The best small speaker available at any price, also $50, is the Tribit Stormbox Micro 2: $34.19 Aliexpress Amazon
Pros: Best in class sound. Much deeper bass than most other speakers in the size. Built in strap is super useful for attaching it to things. Very neutral. To have it aimed directly at you unclip the strap and the speaker will sit upright with a slight lean back.
Cons: Finicky phone charging, which doesn’t usually work.
Setup: Use in Music EQ mode, when you switch to custom it’s not able to boost the bass properly as it is missing an EQ band that Music EQ mode uses

Best Large Under $100
The best large speaker under $100 reaches the top 15% of a 75-speaker class — the Soundcore Boom 2: $89.99 Amazon Bhphotovideo
Pros: Pretty deep bass for the size. Cool lights in the side passive radiators. For the best sound quality use Oluv’s EQ or Alan Ross’s EQ. With the stock tuning, this speaker would rank around #24, due to the boosted bass and rising treble.
Cons: Only a single midrange driver, so you only get stereo for the tweeters. Sound processing issues with inconsistent bass notes that disappear at low levels like the Soundcore Boom and Soundcore Boost, not great for listening at low levels. Quite bass heavy with BassUp turned on, I’d recommend turning it off. A little bit of a bright tuning in the treble, about +5db.

Where $100 Still Falls Short
Boombox and party speakers are not yet good at this price. The best boombox option under $100 sits in the bottom half of its class, and the best party option is little better. If you need either size, the money is better spent stretching to under $200, where a genuinely strong boombox appears.
The most reasonable party-size option if $100 is a hard ceiling is the Klipsch Gig XXL: $79.99 Amazon
Pros: Really amazing value for the money
Cons: Not quite as clean sounding as the top ranked speakers. Not quite as deep of bass Partybox 110. Bass gets muddy at high volume. Low battery life. No water rating
