How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a secure ear-hook fit that survives heavy sweat and rain during hard outdoor training, choose WAVEFUN Headphones; if you need active noise cancellation with a charging case that stretches total listening time much further, choose ZREVSB Earbuds Gen.
• WAVEFUN Headphones — biggest strength: IPX7 waterproofing plus a silicone ear-hook design built specifically for running, hiking, cycling and gym sessions, with up to 15 hours of music time per charge.
• WAVEFUN Headphones — biggest trade-off: It uses sound isolation rather than active noise cancellation, and control is via push buttons on the earpieces instead of touch.
• ZREVSB Earbuds Gen — biggest strength: Active noise cancellation, a customized dynamic driver tuned for balanced bass and clear mids, and a charging case that extends total playtime to 36 hours.
• ZREVSB Earbuds Gen — biggest trade-off: Its IPX5 rating resists sweat, splashes and light rain but is a lower water-protection class than IPX7, so it is not the pick for the wettest conditions.
• Who each pick is for: WAVEFUN for the outdoor athlete who puts waterproofing and a locked-in fit first; ZREVSB for the commuter, traveler or office worker who wants to mute the world around them.
The WAVEFUN Headphones, sold under the Wavefun XBuds model name, are built around one idea: staying put while you move. The earpiece shape is a hook, and the housing combines plastic with silicone ear hooks, so the buds are designed to sit firmly rather than rely on the seal of your ear canal alone. If you have ever had a bud pop out mid-sprint or while bending over a barbell, that hook design is the whole point. The package includes XS, S, M and L ear tips, so you can dial the in-ear fit before you ever clip them on.
On the water front, the shell uses a highly sealed construction plus nano-coating to reach the IPX7 standard — a genuinely meaningful level of protection for sweat-heavy training, rain, and the kind of drenching a long hike or a wet bike ride can hand you. Sound comes from an 11mm dynamic driver paired with Bluetooth 5.3 and AAC transmission, tuned for a bass-forward, loud presentation. Battery sits at up to 15 hours of music time per charge, with a full charge taking about 2 hours off a 120mAh battery, and the headphone battery status shows on your iOS or Android screen. A built-in mic handles calls with voice notification of incoming calls, and push-button controls let you skip, play, pause and adjust volume without pulling out your phone.
Who should buy it: runners, joggers, hikers, cyclists and gym regulars who want a hook-secured, IPX7-rated bud and dislike touch controls. Who should skip it: anyone who wants active noise cancellation for flights or a noisy open-plan office — this one relies on sound isolation, not ANC — and anyone who prefers an ultra-discreet in-ear look over a visible ear hook. The kit also includes a carry case, charging cable, user manual and hanging buckle, and the warranty runs 1 year.
The ZREVSB Earbuds Gen takes the opposite approach. Instead of gripping your ear from the outside, it keeps things compact and in-ear, with lightweight housing and a soft in-ear structure designed to stay comfortable through long wearing sessions. The headline feature is intelligent active noise cancellation, which targets ambient noise, traffic sounds and office chatter to carve out a quiet private audio space. For a commute, a flight, a shared workspace or a long study block, that is the feature that changes how the product feels day to day.
Sound is handled by a customized dynamic driver with professional tuning, aiming for balanced bass, clear mids and crisp highs across a 20Hz–20,000Hz range, over Bluetooth 5.3 with a 10-meter range. Battery is where the numbers get interesting: a single charge covers roughly 5–6 hours of playback, and the included charging case adds 3–5 full recharges for up to 36 hours of total playtime. There is also a Share Mode, so you can hand one earbud to a friend or family member and listen to music, podcasts or calls together. First-time pairing is a matter of opening the case and selecting the buds in your Bluetooth settings; after that they reconnect automatically when you take them out.
The water story is IPX5 — sweatproof and splash-resistant, fine for running, gym work, cycling and light rain, but a step below IPX7. Who should buy it: commuters, travelers, office workers, students and anyone who values quiet and total battery runtime over maximum water protection. Who should skip it: swimmers, heavy-rain trail runners or anyone whose workouts leave gear genuinely soaked — that is WAVEFUN territory. The box includes a cable, charging station, ear tips and user manual, and the warranty runs 2 years.
• Best for heavy sweat and rain → WAVEFUN Headphones. IPX7 is the higher water-protection class here, versus IPX5 on the ZREVSB.
• Best for blocking out noise → ZREVSB Earbuds Gen. Active noise cancellation versus sound isolation is the single biggest functional gap between them.
• Best for total battery life → ZREVSB Earbuds Gen. Up to 36 hours with the charging case beats 15 hours per charge on the WAVEFUN.
• Best for a locked-in fit during hard movement → WAVEFUN Headphones. The silicone ear-hook design is purpose-built to stay in place.
• Best for long, comfortable wear sessions → ZREVSB Earbuds Gen. Lightweight in-ear housing with a soft structure made for extended listening.
• Best for bass-forward workout sound → WAVEFUN Headphones. An 11mm dynamic driver tuned for super bass suits high-energy training.
• Best for commuting and travel → ZREVSB Earbuds Gen. ANC plus a pocketable charging case fits the transit routine better.
• Best for hands-on control without touch fumbling → WAVEFUN Headphones. Push-button media control is easier with sweaty or gloved hands.
If I had to pick one, I would buy the WAVEFUN Headphones, because the IPX7 rating and ear-hook fit are exactly what the hardest part of outdoor training demands, and 15 hours per charge comfortably covers a week of workouts. That said, my recommendation flips if your priority is quiet: the ZREVSB Earbuds Gen is the one I would choose for commuting, travel and long days where ANC and 36 total hours matter more than the highest water rating. In my opinion, pick WAVEFUN for weather and movement, and ZREVSB for silence and stamina. Either way, check the current price on Amazon before deciding, since that is where the final call usually gets made.
are ipx7 earbuds waterproof
IPX7 means the device is rated to withstand immersion in water under defined test conditions, so it is water-resistant to a high degree rather than merely splash-proof. The WAVEFUN Headphones carry an IPX7 rating using a sealed shell plus nano-coating, which is why they suit sweat-heavy sports and wet outdoor use. The ZREVSB Earbuds Gen are rated IPX5, which resists sweat, splashes and light rain but sits a class below IPX7.
can you shower with ipx7 earbuds
An IPX7 rating indicates protection against immersion, so a shower is within the kind of water exposure the standard addresses. The WAVEFUN Headphones, rated IPX7, are the better match of the two for that scenario. The ZREVSB Earbuds Gen at IPX5 are aimed at sweat and splashes, so I would not treat them as the shower-friendly option.
which one has better battery life
The ZREVSB Earbuds Gen wins on total runtime: up to 36 hours when you count the charging case, with roughly 5–6 hours per single charge. The WAVEFUN Headphones deliver up to 15 hours of music time per charge with about a 2-hour charge time. If you hate recharging, the case-based ZREVSB setup is the more forgiving one.
do these have noise cancellation
Only the ZREVSB Earbuds Gen has active noise cancellation, which targets ambient noise, traffic and office sounds. The WAVEFUN Headphones use sound isolation instead, meaning the in-ear seal reduces what you hear rather than electronically cancelling it. Choose ZREVSB if quiet is the goal, and WAVEFUN if secure fit and water protection come first.
