If you want a wired, detail-first in-ear monitor for critical listening and stage work, choose BASN Mix-PD; if you need a fully waterproof, wireless-and-MP3 swim companion that stays put underwater, choose SANOTO Swimming Headphones.
• BASN Mix-PD — biggest strength: A hybrid planar + dynamic driver setup in a CNC metal-and-resin shell, with a detachable silver-plated OFC 2-pin cable for real cable-swapping flexibility.
• BASN Mix-PD — biggest trade-off: It's wired only ("Not capable" of wireless) and has no water-resistance rating, so it's a dry-land, stationary-ish listen, not a pool tool.
• SANOTO Swimming Headphones — biggest strength: IPX8 waterproofing rated for submersion up to 10 meters for over 2 hours, plus a built-in 8GB MP3 player that works where Bluetooth can't.
• SANOTO Swimming Headphones — biggest trade-off: No wired jack, no noise control, and Bluetooth simply can't transmit underwater — you must switch to MP3 mode in the water.
• Who each pick is for: BASN Mix-PD for musicians, monitors and detail listeners; SANOTO for swimmers, surfers and water-sport users.
The BASN Mix-PD is built around a hybrid driver design — a planar driver paired with a dynamic driver. In plain terms, that combination is the reason it can claim both a wide soundstage (planar's strength) and clear, deep bass (the dynamic driver's job). BASN says the tuning was refined across low, mid and high frequencies for "precise and accurate" reproduction. Spec-wise, the frequency range runs 20–40 kHz, impedance is 31 ohm, and sensitivity is 106 dB — numbers that suggest it's easy enough to drive from a phone or portable player, while still having headroom on pro gear.
The physical build is where this thing earns its keep. The shell mixes CNC-crafted metal with durable resin, and the cable is a silver-plated OFC design with a detachable 0.78 mm 2-pin connection. That detachable cable is the detail I care about most: if a cable wears out or you want a different feel for stage versus portable use, you swap it instead of replacing the whole IEM. The package includes a protective case, a T-shirt clip, earbuds, silicone ear tips and the cable, with a 12-month warranty.
SANOTO Swimming Headphones: Who It's For
The SANOTO S710 is a very different animal. It's an in-ear design with ear hooks made from skin-friendly silicone that flex to fit different head shapes and are meant to be worn alongside a swim cap, goggles and earplugs. The key claim is IPX8: submersible up to 10 meters for more than two hours, and resistant to sweat, rain and splashes. The design also physically blocks water from entering your ears while you swim.
The clever part is the two-in-one mode. It's a Bluetooth 5.4 headphone with a 10-meter wireless range, but it also has a built-in 8GB MP3 player that stores roughly 1,500 lossless tracks and supports MP3, FLAC, WMA, WAV and APE. You double-click the function key to switch modes. This matters because Bluetooth uses the 2.4 GHz band, which water absorbs — so underwater, Bluetooth effectively stops working and you must run MP3 mode. SANOTO states this clearly, and it's the single most important thing to understand before buying. Sound is delivered through a bone-conduction driver with a 360° closed sound cavity and anti-leak acoustics. Battery life is up to 12 hours in MP3 mode and up to 8 hours in Bluetooth mode, with a 2-hour charge time via the included magnetic charging cable. You get 10 replacement ear tips, adjustable elastic straps and a one-year warranty.
Who should buy it: lap swimmers, surfers, divers and anyone doing sweaty outdoor training who wants music without a phone nearby. Who should skip it: critical listeners, people who want wired connectivity (there's no jack), and anyone expecting active noise cancellation — noise control is listed as "None."
Side-by-Side: Which Should You Choose?
• Best for sound detail and accuracy → BASN Mix-PD. Hybrid planar + dynamic drivers tuned across the full range.
• Best for cable longevity and repairability → BASN Mix-PD. Detachable 0.78 mm 2-pin, silver-plated OFC cable.
• Best for battery life → SANOTO Swimming Headphones. Up to 12 hours in MP3 mode, 8 hours in Bluetooth.
• Best for phone-free listening → SANOTO Swimming Headphones. 8GB internal storage, about 1,500 tracks.
• Best for noise isolation on land → BASN Mix-PD. Passive noise cancellation plus multiple ear-tip sizes.
• Best for stage and studio use → BASN Mix-PD. Metal-and-resin build, T-shirt clip, pro-audio compatibility.
• Best for versatility across wet and dry workouts → SANOTO Swimming Headphones. Bluetooth for the gym, MP3 for the pool.
In my opinion, these two barely compete — they solve opposite problems. If your priority is faithful, detailed audio and you're listening on dry land, I'd buy the BASN Mix-PD. The hybrid driver setup, swappable 2-pin cable and metal build make it the more serious listening tool, and the replaceable cable is a genuine long-term win. If you're getting in the water, the SANOTO Swimming Headphones are the only sensible pick here — the Mix-PD simply isn't designed for it. I'd choose based on where you'll actually wear them, then check the current price on Amazon before deciding.
how to clean in ear headphones
For the BASN Mix-PD, wipe the metal-and-resin shells and silicone ear tips with a soft, slightly damp cloth and let them air dry — avoid soaking them, since they carry no water-resistance rating. Because the 2-pin cable detaches, you can clean the earpieces separately from the cable. For the SANOTO S710, rinse the silicone ear hooks and ear tips after pool use and dry them fully before charging.
how to fit in ear headphones
The BASN Mix-PD ships with multiple ear-tip options specifically to match different ear sizes, so try each size until you get a snug seal — that seal is what drives its passive noise isolation. The SANOTO S710 uses flexible silicone ear hooks that adapt to different head shapes and are designed to sit alongside a swim cap, goggles and earplugs without falling off.
how to open in ear headphones
Neither of these is a sealed unit you'd normally open up. The BASN Mix-PD's user-serviceable part is the detachable 0.78 mm 2-pin connection — you unplug and reseat the cable there rather than opening the shell. On the SANOTO S710, the "opening" you'll actually do is switching modes: double-click the function key to move between Bluetooth and MP3, and use the magnetic charging cable to top it up.
how to ear headphones
If you mean how to wear them properly: the BASN Mix-PD goes in with the rounded tip seated in the ear canal and the cable routed over or under the ear to your preference, secured with the included T-shirt clip. The SANOTO S710 seats in the ear canal with the hook wrapping behind the ear for stability — that hook is what keeps it in place during intense swimming and sweating.
