If you want earbuds that survive sweat, stay hooked in place and keep pumping for days between charges, choose sprtoybat Earbuds; if you need headphones that work underwater and let you hear the world around you, choose MARLALL Soft Liquid Silicone. Those two jobs are genuinely different, and that's the whole comparison in one line.
• sprtoybat's biggest strength: 68 hours of total playtime with the charging case, IPX7 waterproofing and flexible TPU ear hooks — a package built specifically for sweaty gym sessions.
• sprtoybat's biggest trade-off: It's a sealed in-ear design, so you're cut off from ambient sound, and the hook style won't suit everyone's ear shape.
• MARLALL's biggest strength: An IPX8 rating and open-ear bone conduction, which means it can go where almost no earbud can — into the water — while leaving your ears open to traffic and surroundings.
• MARLALL's biggest trade-off: Bluetooth doesn't work underwater; you must switch to the built-in MP3 mode, and it delivers 7 hours per charge rather than sprtoybat's marathon figure.
• Who sprtoybat is for: Lifters, runners and gym-goers who want loud, sealed-in sound and battery life measured in days.
• Who MARLALL is for: Swimmers and open-water athletes who need audio underwater or want to keep their ears open for safety.
The sprtoybat Earbuds read like a product designed around one scenario: the gym. The flexible TPU ear hooks plus three sizes of silicone tips (S/M/L) are there to solve the classic problem of earbuds working loose mid-set. Combine that with an IPX7 waterproof rating — enough to shrug off sweat and rain — and you have a set that's meant to be worn hard without you thinking about it.
Where it really separates itself is stamina. sprtoybat quotes up to 8 hours on a single charge, and the case recharges the buds 8–9 times for a total of around 68 hours. Fast charging adds 2 hours of music from just 10 minutes plugged into Type-C, and the LED display on the case shows exactly how much charge is left, so you're not guessing before a session. Bluetooth 5.4 handles the connection, with a stated range of around 15 meters, and the 14.2mm dual-layer graphene drivers are tuned for deep bass — which is what most people actually want when they're pushing through a final set. The ENC microphone is claimed to cut background noise by 75% for calls, useful if you take work calls between workouts.
The honest trade-offs: this is an in-ear, sealed design with passive noise cancellation only, so you won't hear much of what's happening around you. If you run outdoors, that's worth weighing. The listed controls are touch-based on the surface, though the description also mentions physical buttons, so expect to check the actual control scheme carefully before buying. And if you swim laps rather than lift, look elsewhere — IPX7 resists sweat and splashes, not submersion.
Buy it if you want a gym-first pair with hooks that stay put, huge battery life and a clear charge readout. Skip it if you swim, or you need to stay aware of traffic while training outdoors.
The MARLALL Soft Liquid Silicone is a different animal entirely. It's an open-ear, bone conduction headphone with an IPX8 rating — the kind of waterproofing that survives being immersed, which is why the brand positions it for swimming, snorkeling and surfing. That single spec puts it in a category sprtoybat simply doesn't compete in.
The build is the other story. MARLALL uses a skin-friendly, ultra-soft overmold liquid silicone that sits against your ears rather than inside them, with an ergonomic ear-hook shape that spreads pressure out for longer wear. It's lightweight, and because nothing goes into your ear canal, you stay fully aware of your environment — traffic on a road run, other swimmers in a lane, or just the outdoors.
Here's the part that matters most before you buy: Bluetooth does not work underwater. On this model, swimming requires MP3 mode, and the headphones include 32GB of built-in storage along with a magnetic charging cable that lets you manage playlists directly from a computer. You get up to 7 hours of playback from a 1.5-hour charge. There's also a note to dry the microphone after swimming to avoid call problems — a small but real maintenance step.
The trade-offs are honest ones. If you mostly lift weights and want thumping bass, the open-ear design will feel thin by comparison, and 7 hours per charge is a fraction of what sprtoybat offers. If you want to stream Spotify from your phone while swimming, this isn't that product — you have to load music onto the internal memory first.
Buy it if you swim, snorkel or surf and want audio that survives the water, or you want open-ear awareness during outdoor workouts. Skip it if you want maximum battery life and immersive in-ear sound for the gym floor.
Side-by-Side: Which Should You Choose?
• Best for swimming → MARLALL Soft Liquid Silicone. IPX8 immersion protection and MP3 mode; sprtoybat's IPX7 is sweat and splash resistant, not built for laps.
• Best for gym and weight training → sprtoybat Earbuds. Ear hooks, three tip sizes, deep-bass graphene drivers and a sweatproof rating all point at the weights room.
• Best for outdoor safety → MARLALL Soft Liquid Silicone. Open-ear bone conduction keeps you aware of traffic and surroundings.
• Best for immersive, sealed-in sound → sprtoybat Earbuds. In-ear passive isolation plus 14.2mm drivers versus an open design that lets outside noise in.
• Best for call clarity → sprtoybat Earbuds. Its ENC microphone is specified to reduce background noise by 75%; MARLALL asks you to dry the mic after swimming.
• Best for loading your own music without a phone → MARLALL Soft Liquid Silicone. 32GB of built-in storage and direct computer playlist management.
• Best for fast top-ups → sprtoybat Earbuds. 10 minutes of Type-C charging gets you about 2 hours of music.
For the gym specifically, I'd buy the sprtoybat Earbuds. The ear hooks, IPX7 sweat resistance, three tip sizes and 68-hour total battery life all line up with how most people actually train — you charge the case occasionally and forget about it. In my opinion the MARLALL only wins if water is genuinely part of your routine, because that IPX8 rating and MP3 mode are capabilities sprtoybat just doesn't have. Pick based on where you sweat: on the floor or in a pool.
what is best headphones for gym
For a typical gym routine, the sprtoybat Earbuds are the stronger fit of these two: secure ear hooks, IPX7 sweat resistance, three sizes of sport tips and up to 68 hours of total playtime. The MARLALL is better suited to swimming and open-ear outdoor use than to lifting. "Best" depends on whether you need water immersion or just sweat protection.

Look for a secure fit, sweat resistance and enough battery to get through your week — that's the sprtoybat Earbuds here, with flexible TPU hooks and an IPX7 rating. If you want to hear your surroundings while training outdoors, the open-ear MARLALL is the alternative, though it gives up in-ear bass and battery life.
what headphones for gym reddit
The recurring advice in gym threads is usually: hooks over loose buds, sweatproof over stylish, and battery life over everything else. By the specs, sprtoybat matches that brief — hooks, IPX7, 68 hours total. MARLALL answers a different brief, aimed at swimmers who need IPX8 and MP3 mode instead of Bluetooth.
what headphone is good for gym
A good gym headphone stays put during movement and survives sweat. sprtoybat covers both with TPU ear hooks and IPX7 waterproofing, plus touch controls and a 15-meter Bluetooth range. The MARLALL is a fine headphone, but its strengths — IPX8, bone conduction, 32GB storage — are aimed at water sports rather than the gym floor.
