If you want over-ear comfort, active noise cancellation, and long battery life for gym sessions, choose TREBLAB Z2; if you need headphones built for swimming, choose SANOTO Swimming Headphones. For gym use, I’d lean toward TREBLAB Z2 unless your workout regularly takes you into the pool: its over-ear design, Bluetooth multipoint, and up-to-58-hour battery suit long stretches of everyday listening, while SANOTO’s waterproof design and built-in music storage solve a different problem.
TREBLAB Z2 vs SANOTO Swimming Headphones at a Glance
• TREBLAB Z2’s biggest strength: over-ear Bluetooth headphones with active noise cancellation and up to 58 hours of battery life. Trade-off: IPX4 sweat protection is not a swimming specification.
• SANOTO Swimming Headphones’ biggest strength: IPX8 waterproofing and 8GB of built-in storage for music playback underwater. Trade-off: underwater listening requires MP3 mode; Bluetooth is not usable underwater.
• TREBLAB Z2 is for: gym-goers and everyday listeners who want over-ear headphones, noise control, and longer battery life.
• SANOTO is for: swimmers and water-sport users who want a secure in-ear fit and music stored on the headphones.

The trade-off is water protection. IPX4 is listed as sweatproof, but it is not the same as the IPX8 swimming protection specified for SANOTO. I’d skip TREBLAB if you want headphones to wear underwater or if your main requirement is music playback without a phone in the pool. Its up-to-58-hour battery is attractive, but it does not change that basic limitation.
SANOTO’s defining feature is its swimming-focused design: in-ear headphones with ear hooks, IPX8 waterproofing, and built-in 8GB storage. The listed waterproof use is submersion up to 10 meters for more than two hours. That makes this the more relevant option for swimming, surfing, and other water-based activities—not simply a sweatier gym session.
The onboard storage changes how you listen in the water. SANOTO supports MP3, FLAC, WMA, WAV, and APE formats, and its battery is listed for up to 12 hours in MP3 mode or up to eight hours in Bluetooth mode. For swimming, the instructions specify switching to MP3 mode and turning off the phone’s Bluetooth. The product explanation says water interferes with Bluetooth transmission, so its stored music is the practical underwater option.
That same design may be less suitable for someone who wants conventional over-ear gym headphones. SANOTO is in-ear, uses ear hooks, and has no headphone jack. Its stated charge time is two hours. I’d pass on it if your routine is almost entirely dry-land training and your priorities are active noise cancellation, multipoint Bluetooth, or a longer listed battery life.
• Best for a gym-first routine → TREBLAB Z2. Its over-ear design, active noise cancellation, and up-to-58-hour battery are a more direct fit for regular dry-land listening.
• Best for swimming → SANOTO. It is specified for submersion and has built-in storage for music playback underwater.
• Best for active noise cancellation → TREBLAB Z2. Its noise control is listed as active noise cancellation. SANOTO’s listed environmental noise cancellation is a different feature, so don’t treat the two labels as interchangeable.
• Best for listening without a phone underwater → SANOTO. Its 8GB built-in MP3 player lets you store supported audio files on the headphones.
• Best for longer stated battery life → TREBLAB Z2. It lists up to 58 hours, compared with SANOTO’s up to 12 hours in MP3 mode and up to eight hours in Bluetooth mode.
• Best for switching between devices → TREBLAB Z2. Bluetooth multipoint is listed, along with Bluetooth 5.3.
• Best for ear-hook stability in water → SANOTO. Its in-ear hooks are designed for use with swimming gear such as goggles and a cap.
• Best if you want a wired option → TREBLAB Z2. It has a 3.5 mm jack; SANOTO has no headphone jack.
These differences also help rule out tempting but mismatched searches. Someone looking for the best voice assistant earbuds for gym may find TREBLAB’s Google Assistant control relevant, but it is an over-ear headphone, not an earbud. Someone searching for spatial audio sleep headphones for gym should know that neither product sheet lists spatial audio or a sleep-focused design. And if your query is for the best ear clip headphones for gym, neither is an ear-clip model: TREBLAB goes over the ear, while SANOTO sits in the ear with hooks.
For a gym-first routine, I’d choose TREBLAB Z2. In my opinion, its over-ear fit, active noise cancellation, multipoint Bluetooth, and up-to-58-hour battery make it the more useful everyday workout-and-listening option.
I’d choose SANOTO instead if swimming is central to the routine. Its waterproof design and stored-music mode answer needs that TREBLAB’s sweat protection does not. The deciding question is whether your headphones need to go underwater.
