Best overall: the JBL Charge 6 is the strongest all-round choice in this comparison, combining an IP68 rating, a stated 20-hour battery and 40W output. Choose the Bose SoundLink Flex (2nd Gen) for a smaller premium speaker, the Sony ULT FIELD 1 for rugged bass and two-speaker stereo, or the JBL Flip 6 when you want a lighter shower and travel companion.
IP67 is normally enough for splashes, rain, a pool deck and a beach trip, provided the charging port is closed and the speaker is dry before charging. IP68 signals a higher immersion rating, but neither label makes a speaker an underwater device.

IP67: temporary immersion
IP67 combines dust-tight construction with protection against temporary immersion under defined laboratory conditions. RTINGS describes the Bose SoundLink Flex as immersible in up to 1 metre of water for 30 minutes. That description applies to the Flex test information, not automatically to every IP67 speaker or every real-world accident.
For practical use, IP67 is a sensible minimum for a speaker that may face a pool party, a wet beach bag or a shower splash. Tom’s Guide recommends at least IP54 for ordinary splash resistance and IP67 when a speaker is expected to cope with a pool party or beach trip.
IP68: a higher, condition-specific rating
IP68 indicates a higher immersion rating than IP67, but the test depth and duration must be specified by the manufacturer or testing documentation. The Charge 6 is listed as IP68 in the 2026 comparison, while that listing does not provide a depth-and-time figure. Do not convert “IP68” into permission to leave the speaker submerged or use it as an underwater speaker.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What the rating does not cover
- Water resistance does not promise protection from impact damage, a cracked enclosure, worn seals or a charging flap left open.
- Salt water, chlorinated water, sand and soap can be more troublesome than a brief splash. Rinse residue with fresh water only when the manufacturer allows it.
- Water resistance can change as a speaker ages or is repaired. Treat the rating as a design specification, not a lifetime warranty.
- None of the four models has a documented floating specification in the supplied product information. Assume a dropped speaker can sink.
Best overall for beach and pool: JBL Charge 6
The Charge 6 is the easiest recommendation when your priorities are endurance and protection. What Hi-Fi’s 2026 comparison lists an IP68 rating, 20 hours of battery life, 40W power and USB-C connections, and names it the best waterproof speaker overall.
Why it suits long outdoor days
- Battery: the stated 20-hour figure is the longest battery claim in this comparison. Actual runtime varies with volume, content, temperature and other operating conditions.
- Water protection: IP68 gives it the highest published water rating here, although the cited listing does not state the exact immersion depth or time.
- Output: the listed 40W power points to a speaker intended to provide more output than the smaller travel options. Wattage alone does not predict tonal balance or maximum clean volume.
- Charging: USB-C connections make the connector familiar and widely supported. The port still needs to be closed and completely dry before charging.
Who should choose it
Choose the Charge 6 if you will spend a full day outside, want fewer charging breaks or need more headroom for a group at a beach or pool. Its larger class of enclosure is less convenient than the Flip 6 for a small shower shelf or a tightly packed day bag.

Important qualification
The 20-hour, IP68 and 40W figures are specifications reported in the 2026 What Hi-Fi comparison. Verify the regional model, included accessories and current price before buying because those details can change by market and production run.
Best compact premium option: Bose SoundLink Flex (2nd Gen)
The SoundLink Flex (2nd Gen) is the choice for readers who value a compact enclosure and refined listening over the longest stated battery or the highest published water rating. Bose’s current guidance says compatible SoundLink models with IP67 protection are built for “rain, splashes, poolside use, and other outdoor environments,” while cautioning that they should not be used as underwater speakers.
Recommended Free Tools
What the IP67 evidence means here
Bose describes the rating as dust protection and temporary immersion. RTINGS describes the SoundLink Flex as fully dust-tight and immersible in up to 1 metre of water for 30 minutes. Keep that test description attached to the Flex; it is not a blanket promise for every IP67 product.
Best use cases
- Poolside listening where the speaker may get splashed but will normally sit above the waterline.
- Rainy walks, patios and campsites where compact size matters.
- Listeners who want a premium small speaker and are willing to trade away the Charge 6’s published 20-hour endurance.
The supplied product notes do not state a battery figure, pairing method, port design or price for the second-generation model. Check the exact regional listing for those details instead of assuming they match another SoundLink version.
Best rugged bass alternative: Sony ULT FIELD 1
Sony positions the ULT FIELD 1 as a compact, rugged speaker with an extra-bass feature. Its product specification states IP67 waterproof and dustproof protection, up to 12 hours of playback per charge and the ability to link two units for stereo pairing. Sony describes it as ready for the elements with an “IP67 waterproof and dustproof rating.”
Rank #3

- What You Get: Anker USB-C Hub (7-in-1), welcome guide, 18-month warranty, and our friendly customer service.
Why choose it
- Bass-focused sound: the ULT feature is aimed at listeners who want more low-end impact from a small enclosure. Extra bass can consume more power and may be less suitable when you need maximum clarity at high volume.
- Stereo expansion: two ULT FIELD 1 units can be linked for stereo, which can create a wider presentation than one speaker. You need two compatible units for this setup.
- Battery: Sony’s “up to 12 hours” is a maximum claim under stated test conditions; louder playback and bass processing can reduce it.
- Protection: IP67 covers dust and temporary immersion, but Sony’s cited page does not specify an immersion depth and duration beyond the rating.
The ULT FIELD 1 is a good middle ground when the Charge 6 feels larger than necessary and the Flip 6’s PartyBoost ecosystem is not relevant to you.
Best small travel and shower option: JBL Flip 6
The Flip 6 is the practical choice for showers, short trips and smaller bags. JBL’s specification sheet lists IP67 waterproof and dustproof protection, 12 hours of playtime, wireless Bluetooth streaming and PartyBoost pairing with compatible speakers.
Where it makes the most sense
- Shower: it has the same IP67 class of protection recommended for pool-party and beach exposure, while its smaller portable format is easier to place away from a direct spray.
- Travel: the 12-hour claim covers a typical day out without the bulk of a larger speaker.
- Multiple speakers: PartyBoost can link compatible speakers when you want more coverage than one unit provides.
The Flip 6 does not have the Charge 6’s published 20-hour battery or IP68 rating. Select it because you value portability, not because IP67 is a guarantee against every drop, submersion or charging mistake.
Which speaker fits each location?
For the beach
Sand makes the beach a more demanding environment than a clean patio. The Charge 6 is the strongest fit on paper because of its IP68 listing, 20-hour battery and 40W specification. The Bose SoundLink Flex, Sony ULT FIELD 1 and JBL Flip 6 are all reasonable IP67 alternatives when their smaller formats or sound profiles matter more.
- Keep the speaker on a raised, stable surface rather than directly in loose sand.
- Do not bury it or brush sand across open connectors.
- After the session, remove visible grit before opening any port cover.
For the pool
Poolside use usually means splashes rather than immersion. Any of the four ratings is sufficient for that scenario when the speaker remains closed and intact. The Charge 6 gives the most battery margin; the Bose is the compact premium option; the Sony adds a bass mode and stereo expansion; and the Flip 6 is easiest to carry.

Keep every speaker away from the pool edge if a fall would be likely. None of the supplied specifications documents floating behavior, so do not rely on recovery if it enters the water.
For the shower
A shower exposes a speaker to spray, steam and soap residue. IP67 models are the most practical size choices: the Flip 6 for portability, the Bose for compact premium sound, and the Sony for bass emphasis. The Charge 6 can work when its larger body is acceptable, but its extra capacity is rarely necessary for a short shower.
- Place the speaker outside the direct spray and away from shampoo bottles that can knock it down.
- Never charge it in the shower or while the USB-C area is damp.
- Wipe off soap or mineral residue and let the enclosure dry before storage.
How to use a water-resistant speaker safely
- Inspect the enclosure. Check that the body, seams and port cover are intact. A cracked shell or damaged seal changes the risk calculation.
- Close every protective flap. Confirm that the charging-port cover is fully seated before the speaker is near water.
- Place it above the splash zone. Use a stable ledge, table or dry bag pocket; do not assume the unit floats.
- Keep charging separate from listening. Disconnect cables before exposure to water. Do not connect a charger until the speaker and connector are completely dry.
- Rinse residue appropriately. If the manufacturer permits rinsing, use fresh water after salt or chlorine exposure. Avoid forcing water into seams or ports.
- Dry before storage. Wipe the exterior, leave the port cover open only in a dry area while moisture evaporates, then close it for transport.
Battery, charging and runtime expectations
Published battery numbers are maximum or stated figures, not a universal playback guarantee. The Charge 6’s 20 hours, Sony’s up to 12 hours and Flip 6’s 12 hours are measured or presented under each maker’s conditions. Volume, bass enhancement, Bluetooth distance, temperature and battery age all affect actual runtime.
There is no supplied battery figure for the Bose SoundLink Flex (2nd Gen), so do not infer one from a previous generation or another SoundLink model. If runtime is your deciding factor, compare the exact regional product page and test conditions.
Water resistance and charging are separate concerns. A speaker can survive a splash yet be damaged if moisture remains around the USB-C connector when power is applied. Wait until the port and plug are dry; never use a charging cable as a test for whether hidden moisture remains.

Stereo and multi-speaker setups
| Model | Documented linking feature | What you need |
|---|---|---|
| JBL Charge 6 | Not stated in the cited comparison | Check the current regional documentation before buying multiple units for linking |
| Bose SoundLink Flex (2nd Gen) | Not stated in the supplied product notes | Confirm compatibility with the exact generation and app before purchase |
| Sony ULT FIELD 1 | Two-unit stereo pairing | Two ULT FIELD 1 speakers and the supported pairing procedure |
| JBL Flip 6 | PartyBoost pairing for compatible speakers | Compatible PartyBoost speakers; compatibility is not implied for every JBL model |
Pairing two speakers can improve stereo width or coverage, but it also doubles charging needs and creates another device to protect from water. For a single-person shower, one speaker is simpler and less likely to be knocked down.
Care and troubleshooting after water exposure
The speaker sounds muffled
Water on the grille can temporarily reduce treble and volume. Stop increasing the volume, move the speaker to a dry ventilated place and allow the enclosure to drain and dry. Do not poke the grille or use high heat, which can damage seals and drivers.
The speaker will not charge
Disconnect the cable and inspect the port for moisture, sand or residue. Leave the speaker unplugged until fully dry, then retry with a known-good cable. If charging still fails, treat it as a possible connector or seal problem rather than repeatedly applying power.
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Bluetooth pairing fails after a beach trip
Move away from crowded wireless areas, restart the speaker and phone, and remove the old pairing entry before pairing again. Sand or moisture should be dealt with separately; a successful Bluetooth connection does not prove the charging port is safe.
There is visible corrosion or a damaged cover
Stop exposing the speaker to water. Rinse only if the manufacturer allows it, dry it thoroughly and contact the manufacturer or an authorized service provider. A damaged flap or cracked enclosure means the original IP rating can no longer be assumed.
Quick Recap
Buying checklist
- Choose the rating: IP54 is a splash-resistance baseline; IP67 is the practical target for pool parties and beach trips; IP68 is a higher rating only when its specific test conditions are understood.
- Match battery to the outing: Charge 6 has the longest stated figure here at 20 hours; Sony ULT FIELD 1 and JBL Flip 6 list 12-hour figures; Bose’s figure is not stated in the cited notes.
- Decide how much speaker you need: Charge 6 favors output and endurance, Bose favors compact premium use, Sony favors rugged bass and stereo pairing, and Flip 6 favors small-bag portability.
- Check pairing requirements: Sony requires two ULT FIELD 1 units for stereo; Flip 6 uses PartyBoost-compatible speakers. Confirm features for the exact model generation.
- Verify the regional listing: Confirm model number, included cable, warranty terms and current price before ordering. Prices and availability are not established in the cited comparison material.
- Plan for drying: A speaker that cannot be dried safely before charging is a poor choice for your environment, regardless of its IP number.
