How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want everyday sweat-proof earbuds for the gym, a run or a commute, choose SGNICS Earbuds; if you need a helmet-mounted intercom and audio system for a motorcycle, dirtbike or snowmobile, choose TOUCH TWO C9. These two share one label — IPX6 waterproof — and almost nothing else. One sits in your ears. The other bolts to the outside of a helmet.
• SGNICS Earbuds — biggest strength: true wireless in-ear earbuds with flexible ear hooks, Bluetooth 5.3, 9 hours per charge and 48 hours total from the 500mAh case, all rated IPX6 against sweat and rain.
• SGNICS Earbuds — biggest trade-off: they're a personal listening device only — no intercom, no rider-to-rider talk, no helmet mount, and the ear-hook shape isn't for everyone.
• TOUCH TWO C9 — biggest strength: a 1000mAh battery rated for up to 70 hours of music and 50 hours of call/intercom use, plus a two-way intercom that links two riders within a stated 600m (1970ft) range, Bluetooth 5.4 and IPX6.
• TOUCH TWO C9 — biggest trade-off: it's built for helmets, not ears. It only intercoms with the same model, needs mounting adhesives and clips, and it comes in black plastic.
• Pick SGNICS Earbuds if you want one pair of earbuds for workouts, calls and daily listening.
• Pick TOUCH TWO C9 if you ride and want audio and intercom inside your helmet.
SGNICS Earbuds are the straightforward choice for anyone who wants a single pair of true wireless earbuds to cover workouts, calls and casual listening. The design leans into stability: soft, flexible ear hooks sit over the ear to keep the buds anchored, and three sizes of silicone tips (S/M/L) let you tune both the seal and the passive noise blocking. If you've had buds pop out mid-sprint, that hook design is the whole point of this product.
The spec sheet fills in the practical details. Bluetooth 5.3 handles the wireless link, and the microphone array uses environmental noise canceling to keep your voice clear on calls — the kind of thing that matters when you take a call on a noisy street or between sets. Battery life is rated at 9 hours in the buds themselves, with a 500mAh charging case that extends total playback to 48 hours and recharges over USB-C in about 1.5 hours. The IPX6 rating covers sweat and rain, which is exactly the abuse these will see at the gym or on a wet run.
Sound-wise, SGNICS pairs a dynamic driver with a 20Hz–20,000Hz frequency range and describes deep bass with clear treble — standard tuning for workouts, where you want a bit of low-end push. Active noise cancellation is listed among the controls, and the buds use touch controls rather than buttons. Compatibility is broad: iPhone, Android, Samsung Galaxy, iPad Pro, Bluetooth-enabled tablets and phones.
TOUCH TWO C9: Who It's For
TOUCH TWO C9 is a different category of device entirely. It's a motorcycle helmet Bluetooth headset — a wireless unit with speakers and microphones that mounts inside a helmet, not in your ears. The kit includes round speaker adhesives, a square microphone adhesive, single- and double-sided speaker adhesive, a clip-on base, a charging cable, a wireless unit and two headset/microphone pieces. In other words, you're installing it, not wearing it.
The headline features are intercom and battery. The two-way intercom lets two riders talk in real time within a stated 600-meter (1970ft) range — genuinely useful when you ride with a partner or a friend. One caveat the spec sheet is explicit about: it only connects to the same model of helmet speakers, so it's not cross-compatible with other brands of Bluetooth helmet units. Buy it as a pair if you want the intercom to work.
Audio comes from 50mm PEN speakers paired with ENC noise cancellation for background noise reduction, and the frequency range matches SGNICS at 20Hz–20,000Hz. The controls are physical: push buttons and voice control, with one-click activation of your phone's voice assistant or Siri for calls, music and GPS. For riders, big buttons you can find with gloves on are a real advantage over touch panels.
Battery is the standout number: a 1000mAh lithium-ion cell rated for 70 hours of music, 50 hours of call or intercom use, and 120 hours of standby, recharging over USB-C in 1.5 hours. Bluetooth 5.4 gives it the newer wireless standard, and IPX6 covers rain and road spray. The drivers are described as over-ear placement with a circular earpiece shape, plastic enclosure, 32 ohm impedance and 110dB sensitivity — easy to drive from a phone.
Who should skip it? Anyone who doesn't ride a motorcycle, dirtbike or snowmobile, and anyone who wants earbuds for the gym. This is helmet gear, and it's designed around that one job.
Side-by-Side: Which Should You Choose?
• Best for workouts and running → SGNICS Earbuds. Ear hooks, three tip sizes and IPX6 sweat protection are built for exactly that.
• Best for total battery life → TOUCH TWO C9. Up to 70 hours of music and 120 hours of standby from a 1000mAh battery versus 9 hours per charge and 48 hours with the case on SGNICS.
• Best for all-day carry in your pocket → SGNICS Earbuds. A 500mAh case that tops up over USB-C in 1.5 hours fits in a bag; a helmet unit does not.
• Best for calls away from a bike → SGNICS Earbuds. Four microphones with environmental noise canceling are aimed at everyday phone calls.
• Best for glove-friendly controls → TOUCH TWO C9. Push buttons and a one-click voice assistant beat touch controls when your hands are covered.
• Best for the newest Bluetooth standard → TOUCH TWO C9. Bluetooth 5.4 versus 5.3 — a small edge, but it's there.
• Best for a single, simple purchase → SGNICS Earbuds. No adhesives, no mounting, no same-model pairing requirement.
For most people reading this, I'd buy the SGNICS Earbuds. In my opinion they're the more useful object for the widest range of buyers: they go in your ears, they stay put thanks to the ear hooks, they handle calls and sweat, and the case carries 48 hours of playback. In my opinion the TOUCH TWO C9 is the better product — but only if you ride. If you do, its 50mm speakers, 1000mAh battery and two-way intercom make it the obvious pick, and the SGNICS buds wouldn't help you at all. Match the product to the activity and you can't really go wrong.
Yes. Both carry an IPX6 rating. For SGNICS that means sweat and rain during workouts; for the C9 it means rain and road spray on a ride. Neither is described as submersible, so don't swim with either one.
It's designed as helmet gear — the kit ships with speaker and microphone adhesives plus a clip-on base for mounting inside a helmet. You could technically power the unit, but the whole product is built around a helmet installation, so it's not a substitute for regular earbuds.
No. The spec sheet states it only connects to the same model of helmet speakers and is incompatible with other brands of Bluetooth motorcycle helmet units. If intercom matters to you, plan on buying matching units.
SGNICS gives you 9 hours in the buds and 48 hours total with the 500mAh case, recharging over USB-C in 1.5 hours. The C9 uses a 1000mAh battery rated for up to 70 hours of music, 50 hours of call or intercom use and 120 hours standby, also charging in about 1.5 hours. For a week of commutes, the C9's numbers are far larger.
If either one fits how you actually use headphones, check the current price on Amazon before you commit — that's the one variable this comparison can't cover.
