If you want everyday wireless earbuds with a charging case and touch controls for workouts, commutes and calls, choose SGNICS AGM G2; if you need headphones you can actually wear fully submerged in a pool and play music from built-in storage, choose Tayogo Bone Conduction Swimming.
• SGNICS AGM G2 — biggest strength: a true wireless in-ear design with 13mm dynamic drivers, a charging case that stretches total battery life to roughly 31 hours, Bluetooth 5.3 and touch controls. It's a normal pair of earbuds you'd reach for every day.
• SGNICS AGM G2 — biggest trade-off: the IPX4 waterproof rating covers splashes, sweat and light rain, not submersion. This is not a swimming headphone, and there's no built-in music storage — it needs a Bluetooth connection.
• Tayogo Bone Conduction Swimming — biggest strength: an IPX8 rating that's designed for full submersion, plus 32GB of onboard storage so you can swim laps with music and no phone anywhere near the water.
• Tayogo Bone Conduction Swimming — biggest trade-off: Bluetooth doesn't transmit underwater, so while swimming you're limited to the MP3 files stored on the headset itself. It's an open-ear bone conduction design, not a noise-isolating earbud.
• Who each pick is for: SGNICS AGM G2 for the gym-goer, runner or commuter who wants one pair of wireless earbuds for everything on land; Tayogo Bone Conduction Swimming for the lap swimmer, snorkeler or water-sports athlete who wants audio in the water.
The AGM G2 is a conventional true-wireless earbud setup, and that's exactly the point. Each bud houses a 13mm compound diaphragm driver, which is on the larger side for this style of earbud and is the kind of spec a manufacturer uses when it wants fuller low-end and more detail in the midrange. They weigh 3.8g each and use an in-ear fit, so they sit inside the ear canal rather than resting outside it. In my opinion that makes them the better pick for anyone who wants music to feel present and close, whether that's on a treadmill, on a train or on a call.
Battery is the other headline. The buds run about 7 hours per charge, and the case recharges them three to four times over, for roughly 31 hours of total playtime with both earbuds in use. Bluetooth 5.3 keeps power draw low and the signal stable out to around 12 meters, and the case auto-reconnects to your last device as soon as you open it. Touch controls handle play, pause, track skipping and calls, and there's an ENC microphone for voice pickup, plus Siri wake-up. A noise-cancelling mic is genuinely useful if you take meetings or calls in a noisy room.
Who should buy it: anyone who wants one pair of wireless earbuds to cover workouts, commuting, calls and casual listening, and who values long total battery life and a case that lives in a pocket. Who should skip it: swimmers and anyone planning to submerge their headphones. IPX4 means it tolerates sweat and splashes, not a pool. If your main use is water, this isn't the product — no amount of spec-sheet reading changes that.
The Tayogo is a different animal entirely, and it's built around one job: audio in the water. The IPX8 rating is the highest tier of water protection, and the manufacturer states it's designed for use fully submerged, with clear audio down to 3 meters (roughly 10 feet). That covers lap swimming, snorkeling and most water sports. Instead of pushing sound through the ear canal, it uses bone conduction to transmit vibration directly to the inner ear, which is why it still works when water would normally block a traditional earbud.
The 32GB of internal memory is the second half of the story. That's enough for thousands of songs, and you load them by dragging and dropping MP3, WMA, WAV or APE files from a Mac or PC — no app gymnastics required. The reason that matters: Bluetooth signals don't travel through water, so while you're swimming you switch to MP3 mode and play from the headset itself. Bluetooth 5.4 is there for land-based use, with a 10-meter range, and it's fine for running, gym work or walking.
Who should buy it: lap swimmers, triathletes, snorkelers and anyone whose training happens in the water, plus runners who want open-ear awareness of traffic. Who should skip it: anyone who wants a pocketable everyday earbud with a charging case and touch controls, or who relies on streaming services while working out. This one plays what you've loaded onto it.
Side-by-Side: Which Should You Choose?
• Best for swimming → Tayogo Bone Conduction Swimming. IPX8 and full submersion to 3 meters; the AGM G2's IPX4 is splash-only.
• Best for everyday wireless listening → SGNICS AGM G2. Bluetooth 5.3, auto-reconnect, touch controls and a pocketable charging case.
• Best for total battery life → SGNICS AGM G2. About 31 hours combined versus 8–10 hours on the Tayogo.
• Best for music without a phone → Tayogo Bone Conduction Swimming. 32GB of built-in storage plays with no device connected.
• Best for calls and meetings → SGNICS AGM G2. The ENC noise-cancelling mic and touch call controls are designed for voice.
• Best for hearing your surroundings → Tayogo Bone Conduction Swimming. The open-ear design leaves your ears uncovered.
• Best for a secure fit during vigorous movement → Tayogo Bone Conduction Swimming. The wraparound frame is built to stay put and fit under goggles or a cap.
• Best for a single pair to cover work, travel and gym → SGNICS AGM G2. It's the more versatile all-rounder of the two.
If I had to pick one, I'd buy the SGNICS AGM G2. In my opinion it earns its place because it covers the widest range of everyday situations — commuting, calls, workouts, listening at a desk — with long battery life, a charging case and touch controls, and it's the pair most people would actually use daily. The Tayogo is the better product for its specific job, and if you swim laps it's not even a contest: IPX8 and 32GB of onboard music make it the only sensible choice between the two. But as a general-purpose headphone, I'd take the AGM G2. Check the current price on Amazon before deciding, since that's the one thing the spec sheets can't tell you.
