If you want wireless sport earbuds with a secure hook fit and up to 30 hours of battery life for swimming, choose JVC Fitness Series HAEC25TB; if you need replacement memory-foam tips for compatible Sony earbuds, choose COMPLY TrueGrip MAX Memory. These are different kinds of products, so the deciding question is whether you need a complete pair of earbuds or tips for earbuds you already own.
For swimming, the JVC is the more relevant option because it is a wireless sport earbud set with an IPX5 water-resistance rating. The COMPLY product is a set of replacement tips, not a standalone pair of headphones, and its listed features do not establish suitability for swimming.
• JVC’s biggest strength: a complete true wireless sport-earbud setup with soft-material hooks, three sound modes, and up to 30 hours of battery life with the case. Trade-off: the listed water rating is IPX5, and the product has no noise control.
• COMPLY’s biggest strength: slow-recovery memory foam designed to form a secure seal and help isolate outside noise. Trade-off: these are replacement tips for compatible Sony earbuds, not complete headphones.
• Choose JVC if you need earbuds for exercise, want a hook-supported fit, or are comparing options for swimming and water exposure.
• Choose COMPLY if you already have a compatible Sony true wireless model and want to change the fit or improve passive noise isolation.
• Neither product is a match if you expect the COMPLY tips to work as independent headphones or need an explicit swimming-use claim for the foam tips.
The JVC is a complete pair of in-ear true wireless earbuds built around a sports-oriented fit. Its soft-material hooks are intended to help hold each earbud in place, while the lightweight, compact design is aimed at keeping the fit comfortable and stable. That combination makes more sense for movement than a loose-fitting earbud design. The controls are touch-based, and the product also supports voice assistants.
For workouts and everyday listening, the useful details are the three selectable sound modes—normal, bass, and clear—and the included charging case. JVC lists up to 30 hours of battery life with the built-in battery and case, so the figure applies to the full charging setup rather than just one uninterrupted listening session. An included open-type piece is intended to let surrounding sound through, which may suit situations where awareness matters more than blocking nearby noise.
For swimming, there is an important distinction: the JVC carries an IPX5 water-resistance rating, but that rating alone should not be treated as confirmation that the earbuds are designed for swimming or submersion. The sheet also lists no noise control. If your priority is a secure sport fit and some stated resistance to water exposure, the JVC is the more relevant of these two choices, but check that its water-resistance rating matches your intended use.
Who should skip it: Skip the JVC if you need noise cancellation or a product explicitly described as suitable for swimming underwater.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
COMPLY TrueGrip MAX Memory is a replacement-tip product, not a pair of earbuds. Its slow-recovery foam compresses for insertion and then expands to form a close in-ear fit. That design may appeal to someone whose compatible Sony earbuds feel loose or whose current tips do not create the seal they want. A secure seal can also help reduce outside noise, according to the product information.
The material is described as having SmartSkin Technology for moisture resistance, durability, and easier cleaning. The tips can be gently cleaned with warm water and a soft cloth; alcohol-based cleaners and lotions should be avoided because they can degrade the material. The package includes three pairs in small, medium, and large, giving buyers a choice of sizes. Compatibility is limited to listed Sony true wireless models, including several WF-1000XM and WF-series earbuds, as well as INZONE Buds and LinkBuds S. Confirm your exact model before choosing replacement tips.
The main limitation for a swimming-focused buyer is that moisture resistance in the tip material does not make the tips a swimming headphone, nor does the information establish that they are suitable for swimming. They also depend on owning compatible Sony earbuds: by themselves, the foam tips cannot play audio, connect wirelessly, or provide a charging case.
Who should skip it: Skip COMPLY if you do not own a compatible Sony model or you need a complete set of earbuds rather than replacement tips.
• Best fit for a complete wireless earbud set → JVC Fitness Series HAEC25TB. It includes the earbuds and charging case; COMPLY supplies replacement tips only.
• Best for a hook-supported sport fit → JVC. The soft-material hooks are designed to help keep the earbuds stable during movement.
• Best for a memory-foam seal → COMPLY. The slow-recovery foam is intended to conform to the ear and help hold compatible earbuds in place.
• Best for choosing among sound profiles → JVC. It offers normal, bass, and clear modes; the COMPLY tips do not provide sound settings.
• Best for listed passive noise isolation → COMPLY. Its foam seal is intended to help block outside noise. JVC lists no noise control.
• Best for stated battery life → JVC. Its built-in battery and case provide up to 30 hours according to the product information; COMPLY tips contain no battery.
• Best for a Sony-earbud fit adjustment → COMPLY. The tips are designed for specified Sony true wireless models and come in three sizes.
• Best starting point when comparing products for swimming → JVC, with a caveat. It has an IPX5 rating, but the supplied information does not say it is made for swimming or submersion. COMPLY’s moisture-resistant foam is not a substitute for a swimming-rated earbud.
First, be clear about what you are replacing. If you do not already own compatible Sony earbuds, COMPLY TrueGrip MAX Memory is not a complete listening solution. If you do own a listed Sony model, check the fit and size requirements before buying: a replacement tip only helps if it attaches correctly and suits your ear.
Next, separate a secure fit from water suitability. JVC’s hooks are intended to support stability, while COMPLY’s foam is intended to form a close seal. Those are different approaches, and neither description by itself proves that a product will stay in place for every person or activity. For water use, JVC’s IPX5 rating is a useful fact, but the product information does not say the earbuds are intended for swimming underwater. COMPLY’s moisture-resistant material likewise should not be read as a claim that the tips are made for swimming.
Consider how much outside sound you want to hear. JVC lists no noise control, and its included open-type piece is specifically meant to let surrounding sound through. COMPLY’s foam seal is designed to help isolate outside noise. That makes them serve opposite listening priorities: awareness with the JVC open piece, or a more enclosed fit with the COMPLY tips on compatible earbuds.
For someone searching for the best spatial audio kids headphones for swimming, neither product’s listed features establish spatial audio or a children-specific design. The JVC is the only complete earbud set here, but it is described for adults and its water rating should be checked against the planned activity. Likewise, sweat resistant gaming headphones for swimming is not a precise match for either product: COMPLY is an accessory for compatible Sony earbuds, while JVC’s sheet does not identify it as a gaming headset. And despite the phrase best rotatable ear cups in ear headphones for swimming, neither product lists rotatable ear cups. These distinctions matter more than trying to stretch a search phrase onto a product that does not fit it.
I would choose the JVC Fitness Series HAEC25TB if I wanted a complete wireless sport-earbud set, especially for exercise and cautious consideration of swimming-related use. Its hook-supported fit, three sound modes, and up-to-30-hour battery figure give it more everyday functionality as a standalone product.
For swimming, though, I would not treat IPX5 as a promise of suitability for submersion. I’d choose COMPLY only if I already owned compatible Sony earbuds and specifically wanted memory-foam replacement tips—not as a swimming headphone.
Check the rating against your intended use rather than assuming it is a swimming-specific model.
No. The tips are designed for specified Sony true wireless models, including listed WF-series earbuds, INZONE Buds, and LinkBuds S. Confirm that your exact model is compatible before buying.
COMPLY is designed to create an in-ear foam seal that helps isolate outside noise. JVC lists no noise control, and its included open-type piece is intended to let surrounding sound through.
Decide whether you need complete earbuds or replacement tips. Then check compatibility, fit style, and your intended water exposure: JVC lists an IPX5 rating, while COMPLY’s moisture-resistant foam does not make it a standalone or swimming-specific audio product.
