How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want active noise cancellation, a lighter fit and a headband-style alternative for cycling, choose TONTRU Headphones; if you need maximum total playtime, Bluetooth 5.4 and a locked-in in-ear fit for cycling, choose Generic Earbuds. Both carry an IPX4 waterproof rating, so this is not a contest about surviving sweat and rain — it is a contest about everything else.
• TONTRU Headphones — biggest strength: dual-mode noise cancellation (ANC plus ENC mics, Transparency/Noise Canceling/Off) with up to 30dB of ambient noise reduction, a 13mm dynamic driver, and a very light 3.8g-per-bud semi-in-ear design.
• TONTRU Headphones — biggest trade-off: shorter battery figures on paper — 5 hours per earbud and 20+ hours with the case, against the 30 hours the Generic pair claims.
• Generic Earbuds — biggest strength: Bluetooth 5.4 with BQB and FCC certification, 8 hours on a single charge plus 22 extra from the 300mAh case, and an ergonomic in-ear shape built to stay locked during hard efforts.
• Generic Earbuds — biggest trade-off: ENC only — there is no active noise cancellation mode, so it quiets calls and background noise rather than letting you switch into a true noise-canceling listening mode.
• Pick TONTRU if you want switchable noise modes, a barely-there fit, and a set that doubles as your everyday commuting and work pair.
• Pick Generic Earbuds if you want the longest runtime, the newest Bluetooth protocol, and a fit that refuses to budge mid-ride.
The TONTRU A8 is the more feature-dense of the two, and the feature that separates it is the noise control system. You get dual-microphone ENC for calls plus genuine ANC with three modes — Transparency, Noise Canceling and Off. That is a real, usable toggle, not a marketing label, and it is the reason I would hand these to someone who moves between a noisy commute, an open office and a quiet living room in the same day. The 13mm composite diaphragm driver is the larger of the two designs here, and the spec sheet pairs it with 32 ohm impedance and a dynamic driver, which is the typical recipe for a warmer low end.
Comfort is the second argument. Each earbud weighs 3.8 grams and uses a semi-in-ear shape with soft silicone tips, so nothing is jammed deep into your ear canal. For anyone who finds traditional in-ears fatiguing after an hour, that half-in, half-out approach is the whole point. Add a flip-open lid, touch controls and an LED power display that shows the case's real-time charge, and the day-to-day friction is low. USB-C refills the case in about 1.5 hours.
Where it gives ground: 5 hours per bud, 20+ hours total. If you are the type who forgets to charge, that number will annoy you. Bluetooth 5.3 is a generation behind the Generic pair, and the 32.9-foot range is fine for a phone in your pocket or a laptop across the room — not for wandering a whole house. For cycling specifically, note that the TONTRU listing is an in-ear bud, not a headband headphone, so if you have been shopping for headband headphones for cycling, neither of these is that product; both are true wireless buds. Also worth flagging honestly: these are not made for swimming or showering, and no IPX4 product is.
The Generic TN17 wins on the two specs that matter most to high-mileage users. First, runtime: 8 hours on a single charge, 22 more from the case, 30 total. Each bud carries a 35mAh cell and the case holds 300mAh. Second, connectivity: Bluetooth 5.4, the newer protocol of the two, and the brand states BQB and FCC certification for compatibility. In practice that means faster pairing and a more stable link, which is exactly what you want when your phone is in a jersey pocket and your hands are on the bars.
The fit story is the other half. The TN17 uses an ergonomic in-ear design specifically described as staying locked during running and gym sessions. For cycling, that matters more than most people expect — a bud that works loose on a descent is worse than no bud at all. Combined with IPX4 sweat-proofing and rain resistance, this is the pair I would pick for a wet-weather training block. Audio is rated at 109dB sensitivity with 32 ohm impedance, and ENC handles background noise for calls and voice chat. The warranty is stated as one year, with CE, RoHS and FCC compliance listed.
What you give up is mode flexibility. There is no ANC here and no Transparency mode — ENC reduces noise around your voice and your audio, but you cannot flip a switch and shut the world out. The 1.5-hour charge time matches the TONTRU, so the advantage is purely in how long each charge lasts. If you want a set with a mic for calls — the kind of with mic earphones for cycling buyers search for — both qualify, but the Generic pair's four-mic ENC setup and longer runtime make it the more obvious training companion.
• Best for active noise cancellation → TONTRU Headphones. It is the only one of the two with real ANC and a Transparency mode.
• Best for battery life → Generic Earbuds. 8 hours per charge and 30 hours total beats 5 and 20+.
• Best for all-day comfort → TONTRU Headphones. 3.8g per bud and a semi-in-ear shape that does not plug the canal.
• Best for cycling and workouts → Generic Earbuds. The in-ear ergonomic fit is designed to stay put under effort, and the longer runtime covers a long ride.
• Best for the newest Bluetooth → Generic Earbuds. Bluetooth 5.4 versus 5.3, plus BQB and FCC certification.
• Best for commuting and office use → TONTRU Headphones. Flip between Noise Canceling and Transparency without touching your phone.
• Best for long-haul travel → Generic Earbuds. 30 hours total means fewer top-ups in transit.
• Best for lighter, less intrusive wear → TONTRU Headphones. If in-ear buds always feel like too much, start here.
For cycling, I would buy the Generic Earbuds. The locked-in in-ear fit, the 30-hour total runtime and Bluetooth 5.4 line up almost perfectly with what a rider actually needs: a bud that stays seated, lasts a full week of rides between charges, and reconnects fast when you pull your phone out at a traffic light. The TONTRU pair is the better all-rounder for commuting and calls because of the switchable ANC, and if noise modes and a featherweight fit matter more to you than runtime, that is the smarter buy. If you are specifically hunting open ear headphones for cycling, keep looking — neither of these is an open-ear design. In my opinion, riders should default to the Generic Earbuds; everyone else should weigh ANC against battery and pick accordingly. Either way, check the current price on Amazon before you commit, since both change hands often.
can i wear waterproof headphones in the shower
No — and that applies to both of these. IPX4 covers sweat and light rain splashes, not direct jets of water. Showering, swimming and submerging are outside what an IPX4 rating is meant to handle.
are headphones waterproof
IPX4 is water-resistant, not waterproof. It means the earbuds are protected against splashing water and perspiration, which is why both the TONTRU A8 and the Generic TN17 are marketed for running, workouts and rain. Neither is rated for immersion.
The Generic Earbuds, based on the specs. The in-ear ergonomic fit is described as staying locked during intense sessions, the 30-hour total runtime covers long weeks of riding, and Bluetooth 5.4 gives the faster, more stable pairing you want with a phone in a jersey pocket.
Runtime and a Bluetooth generation. You get 5 hours per bud and 20+ hours total versus 8 and 30, and Bluetooth 5.3 instead of 5.4. In exchange you gain genuine ANC with a Transparency mode and a lighter 3.8g semi-in-ear fit.
