Waterproof Bluetooth speakers under $100 (2026)

Every speaker here has a water rating of IPX7, IP67 or IP68, as its maker states, and sold for less than $100 on its manufacturer's own US store on October 20, 2026. We don't show prices: they change, so check the current price before you buy. Each value is what the manufacturer states on the linked page; "Not stated" means the page doesn't say.

Five of the six are pocket size by our definition (the sixth, the MP100 Plus, states no weight), and all six carry a water rating with a 7 or 8 as the second digit, which is the part of the code that covers going under water. Five of them also have a 6 as the first digit, so they are rated dust-tight as well; the Edifier MP100 Plus is rated IPX7, which means Edifier rates it for water but not for dust. Two of the makers go further than the code: soundcore calls the Select 4 Go's rating "IP67 Protection and Floats", and UE says the WONDERBOOM 4's IP67 rating lets it "withstand dust, dirt, and water". If you plan to drop a speaker in the pool on purpose, the floating claims are the ones to check on the maker's page.

Battery figures are where they differ most. The soundcore Boom Go 3i states 24 hours and the Select 4 Go and Session 360 state 20, while the MINIROLL states 12 and the MP100 Plus 9. Makers that give a test condition rate playtime at moderate or default volume, so a speaker played loud on the beach will run down sooner than these figures.

• If you want the longest battery → the soundcore Boom Go 3i (24 hours), then the Select 4 Go or Skullcandy Session 360 (20 hours each).
• If it's mainly for the shower → the soundcore Select 4 Go, which soundcore sells as a shower speaker and says floats.
• If you want to take calls → the Edifier MP100 Plus, the only one here whose maker states a built-in mic for calls.
• If you want the lightest speaker with a stated weight → the Skullcandy Session 360 at 0.54 lb, then the MINIROLL at 0.62 lb.
• If you want to pair two for stereo → any of the five that state pairing. UE says MINIROLL's PartyUp can sync "an unlimited number of MINIROLL speakers", and the WONDERBOOM 4 pairs two for stereo. Buy the second speaker from the same family.
• If you want the highest water rating here → the soundcore Boom Go 3i, the only IP68 speaker in this list.

Small waterproof speakers give up some things for their size. None of these six lists Wi-Fi, so they play from your phone over Bluetooth only. Only one of them, the MP100 Plus, states a speakerphone. And the size classification for the MP100 Plus is "Not stated" because Edifier's page gives no weight; it describes the speaker as "ultra-portable" and "handheld", so expect it to be in the same small class as the others.

The WONDERBOOM 4 has one pairing limit worth knowing: UE says it doesn't connect with WONDERBOOM 1 and 2, BOOM, MEGABOOM or HYPERBOOM speakers, so it pairs only with another WONDERBOOM 4.

See every waterproof speaker under $100, or narrow it to waterproof speakers under $50. Raise the ceiling to $200 for bigger portable speakers such as the UE BOOM 4 and the Beats Pill. For a weekend away, see Bluetooth speakers with 20 hours or more of battery. The Bluetooth speaker buying guide explains what each IP code covers.

7 of the 34 speakers we catalogued (as of October 20, 2026) were waterproof (IPX7, IP67 or IP68) and under $100 on their maker's own store. We use the price the maker's store charged, not a crossed-out list price. We picked six that differ in battery, weight, pairing and calls; the seventh, the Skullcandy Session 540 (IP67, 17 hours, 0.71 lb), is in the finder. Picks are ordered by the price on the maker's store, lowest first; the order is not a ranking.
