If you want a pair of everyday wireless earbuds with a huge 32-hour total battery reserve and an in-ear fit built for gym sessions and game days, choose SOAR NBA; if you need headphones you can actually wear in the water — bone conduction, IPX8 submersion, built-in 32GB of music storage — choose Sanag Swimming Bone Conduction.
These two products get lumped together because both are "sport audio," but they solve completely different problems. One is a sealed in-ear earbud aimed at land-based listening and charging convenience. The other is an open-ear bone conduction headset engineered around swimming pools, open water and phone-free playback. Pick the wrong one and you'll be frustrated within a week. Here's how I'd decide.
• SOAR NBA's biggest strength: 32 hours of total battery life with a portable charging case, plus multiple ways to feed it audio — Bluetooth, FM radio, USB and AUX.
• SOAR NBA's biggest trade-off: It's an in-ear, plastic-bodied earbud with no water-resistance rating in the data sheet, so swimming is off the table. It's also Bluetooth 5.0, a step behind newer chips.
• Sanag Swimming Bone Conduction's biggest strength: IPX8 waterproofing with submersion up to 2 meters, a one-piece seamless build, and 32GB of internal memory so you can swim with music and no phone.
• Sanag Swimming Bone Conduction's biggest trade-off: Just 8 hours of playback per charge (about 2 hours to recharge), and you must switch to MP3 mode in the water because Bluetooth can't transmit underwater.
• Who SOAR NBA is for: Anyone who wants simple, long-lasting wireless earbuds for workouts, commutes and watching sports on land.
• Who Sanag is for: Swimmers, pool trainers and open-water athletes who want audio without blocking their ears.
The SOAR NBA is a true wireless in-ear earbud built around one clear idea: keep the music going without hunting for a charger. The headline number is 32 hours of total battery life, and the included charging case is what makes that practical — you top the buds up on the move rather than plugging into a wall. For someone who trains most days and commutes in between, that's a genuinely useful reserve. You're not thinking about battery percentage every session.
The honest trade-offs: the enclosure is plastic, it's an in-ear design (so you're blocking outside sound, not hearing your surroundings), and there is no waterproofing rating listed. That rules it out for swimming, heavy rain, or anyone who wants situational awareness while running near traffic. I'd recommend the SOAR NBA for land-based athletes and casual listeners who value battery life and source flexibility. I'd steer swimmers and open-ear fans elsewhere.
Sanag Swimming Bone Conduction: Who It's For
The Sanag Swimming Bone Conduction is a different animal entirely, and the name tells you why. It's an open-ear, curved bone conduction headset — meaning the driver sits outside your ear canal and transmits sound through vibration, so your ears stay open and you keep awareness of your surroundings. The data sheet lists an impedance of 32 ohm, a frequency response from 20 Hz, 96 dB sensitivity and a bone conduction driver, with low-frequency vibration and a magnetic drive oscillator tuned to hold sound detail even underwater. A fully enclosed sound cavity is designed to reduce leakage.
The real story is water. IPX8 means submersion up to 2 meters, and the one-piece seamless design is built for pool training, ocean swimming, sweat and rain. The internal 32GB of memory is the piece most people miss: you load songs onto the headset and play them without a phone. That matters because Bluetooth cannot transmit through water — the manufacturer explicitly notes you should use MP3 mode while swimming, and switch to Bluetooth when you're dry. The Bluetooth 6.0 chip pairs in about 3 seconds with a stated range up to 50 feet (the spec sheet's connectivity field lists 33 feet — either way, it's a normal wireless working range). Playback runs up to 8 hours per charge, with roughly 2 hours to refill. For calls, the built-in mic uses ENC to cut background noise in pools, gyms and outdoor settings.
Trade-offs worth naming: 8 hours is a fraction of the SOAR's 32, so multi-day trips mean more charging. It's also open-ear by design, which means less isolation and less bass thump than a sealed in-ear bud. Controls are touch-based and on-ear, and the noise control field simply reads "None" — the ENC applies to calls, not to blocking the world around you. In my opinion, the Sanag is the pick for swimmers and open-water athletes who want music in the pool and don't want their ears plugged.
• Best for swimming → Sanag. IPX8 with 2-meter submersion and a seamless one-piece build. The SOAR has no water rating.
• Best for battery life → SOAR NBA. 32 hours total versus 8 hours per charge on the Sanag.
• Best for phone-free playback → Sanag. 32GB of built-in memory plays music with no device at all. The SOAR needs a source.
• Best for audio source flexibility on land → SOAR NBA. Bluetooth 5.0 plus FM radio, USB, AUX and a 3.5 mm jack.
• Best for staying aware of traffic and surroundings → Sanag. Open-ear bone conduction keeps your ears unblocked; the SOAR is a sealed in-ear design.
• Best for clear calls in noisy places → Sanag. Built-in mic with ENC for pools, gyms and outdoors.
• Best for quick pairing and newer wireless → Sanag on paper. It lists a Bluetooth 6.0 chip and 3-second pairing, versus Bluetooth 5.0 on the SOAR.
• Best for a secure in-ear fit during land workouts → SOAR NBA. Silicone ear gels and a charging case for on-the-go top-ups.
If I had to buy one for myself, I'd pick the Sanag Swimming Bone Conduction — but only because its job is the harder one to replace. A headset that survives 2 meters of water, holds 32GB of songs and plays them with no phone is something an ordinary earbud simply cannot do, and that combination is worth the shorter 8-hour runtime. I'd recommend the SOAR NBA instead if you never get in the water and would rather have triple the battery reserve plus FM, USB and AUX inputs. Match the tool to the activity and you won't regret either.
FAQ
I wouldn't. There's no water-resistance rating in the data sheet, and it's a plastic in-ear design. Treat it as a land-only earbud for the gym, field and home.
Not necessarily. It has 32GB of built-in memory, so you can load songs and play them directly. Use Bluetooth when you're out of the water and MP3 mode when you're in it.
The SOAR NBA wins on paper with 32 hours of total battery life and a charging case. The Sanag runs up to 8 hours per charge with about a 2-hour recharge time — plenty for a swim session, less ideal for multi-day use.
