• Avantree E171 — biggest strength: it's a two-piece bundle. You get wired sports earbuds with a microphone plus a pair of hybrid ANC wireless earbuds, so one purchase covers gym duty and commuting duty.
• Avantree E171 — biggest trade-off: the ANC is rated to block up to 24dB of ambient noise. That's a real reduction, but it's a modest figure next to what the TOZO set claims, so don't expect library-level silence on a packed train.
• TOZO NC3 — biggest strength: hybrid ANC rated at up to 45dB of noise reduction depth, backed by six microphones for calls and environmental noise reduction. That's the headline spec here.
• TOZO NC3 — biggest trade-off: the kit centers on earbuds plus a foldable HT2 headphone, and the ANC/ENC story is built around microphones and algorithms rather than a sport-focused fit. If you want hook-secured buds for running, that's not the design brief.
• Who the Avantree bundle is for: people who want one box that handles both workouts and commuting, and who value a snug ear-hook fit over maximum attenuation.
• Who the TOZO kit is for: people who care most about how much noise gets cancelled, and who take a lot of calls in loud places.
The Avantree E171 is really two products in one listing. The Clan N1 side is a wired sports pair with a built-in microphone and an ear-hook design, and the E171 side is a wireless, in-ear set with hybrid ANC. Both lean on the same idea: stay put and stay comfortable for long stretches.
The fit story is the strongest part. You get three sizes of silicone tips, and the ear hooks add a mechanical layer of security that plain in-ear buds don't have. For running, jogging or gym work, that matters more than raw spec numbers — a bud that shifts every thirty seconds ruins a session no matter how good it sounds. Avantree also describes the tuning as well-balanced with solid bass and an emphasis on mids and highs, and openly notes that if you want extra-strong bass, larger headphones are the better route. I appreciate that kind of honesty in a spec sheet.
On the wireless side, you get hybrid ANC rated to cut up to 24dB of environmental noise, Bluetooth 5, a 20Hz–20,000Hz dynamic driver, remote control, and a case with a battery display that shows charge status at a glance. Pairing is automatic the first time you lift the buds out of the case.
TOZO NC3: Who It's For
The TOZO NC3 listing is built around two pieces as well: the NC3 earbuds and the TOZO HT2 headphones. The earbuds carry hybrid active noise cancellation with a claimed noise reduction depth of up to 45dB, and six microphones that monitor ambient noise in real time and pick a suitable reduction level for your ears. That's a lot of microphone hardware for a set of earbuds, and it's aimed squarely at two scenarios — noisy commutes and calls taken in loud places.
The HT2 half leans on a hybrid ANC algorithm with three ANC microphones, and TOZO describes it as controlling noise across a wide frequency range: airplane engine roar, subway rumble, office chatter. There's also ENC call noise cancellation on that side, so your voice comes through more clearly when you're talking on a busy street. The HT2 is also foldable and lightweight, which is a practical detail — it folds down into a bag or travel case instead of eating half your backpack.
So this kit is for the traveller and the heavy caller. If you fly, ride the subway, or sit in an open office, the deeper attenuation figure is the reason to pick this set over the Avantree. The six-mic array and the ENC focus tell me call clarity in noise was treated as a first-class design goal, not an afterthought.
Skip the TOZO if your main use is running or gym work and you want hook-secured buds. Nothing in this listing points to a sport fit. Skip it too if you don't need a second, over-ear style headphone — half the kit may sit unused, and you'd be better served by a single-purpose pair.
Side-by-Side: Which Should You Choose?
• Best for maximum noise cancellation → TOZO NC3. Up to 45dB of hybrid ANC reduction versus up to 24dB on the Avantree. That gap is the single biggest difference between these two listings.
• Best for calls in loud places → TOZO NC3. Six microphones with real-time ambient detection and ENC is a more call-focused setup than the Avantree's single built-in mic.
• Best for a balanced, non-bass-heavy tuning → Avantree E171. Avantree explicitly describes mids and highs emphasis with solid bass, and points bass-chasers elsewhere.
• Best for travel and packing → TOZO NC3. The foldable, lightweight HT2 headphone folds down into a bag, which suits flights and trips.
• Best for battery visibility → Avantree E171. The charging case has a battery display, so you can see charge level instead of guessing. The TOZO listing doesn't describe one.
• Best for a two-in-one purchase → Avantree E171. Wired sport buds plus wireless ANC buds covers gym and commute from one box; the TOZO pairs earbuds with an over-ear headphone instead.
• Best if you want to compare current pricing before deciding → check the price on Amazon for both. Neither listing's specs settle the value question on their own, and the numbers change.
I'd buy the TOZO NC3. The reason is simple: hybrid ANC is the whole point of this comparison, and up to 45dB with a six-microphone array is the stronger noise-cancellation package of the two. Add the foldable HT2 headphone for travel and it covers the scenarios where ANC actually earns its keep — planes, trains, open offices.
I'd switch to the Avantree E171 only if my priority were exercise. The ear-hook fit and the wired sports pair make it the more sensible pick for running and gym work, and the battery display on the case is a genuinely useful touch. But for pure hybrid ANC performance and call clarity in noise, my pick is the TOZO.
FAQ
what is hybrid anc earbuds
what are hybrid anc earbuds
They're wireless earbuds that combine feedforward and feedback noise cancellation in one system. The TOZO NC3 adds a six-microphone array with real-time ambient detection on top of that, while the Avantree E171 pairs its hybrid ANC with a secure ear-hook fit and a battery display on the case.
what is anc earbuds
ANC stands for active noise cancellation: the earbuds generate sound that offsets incoming noise, which is most effective on steady low-frequency sounds like engine drone and air conditioning. It's different from passive isolation, which comes from how well the tips seal your ear canal — which is why the Avantree's three tip sizes matter for fit.
what are anc earbuds
They're earbuds with built-in electronics that actively reduce surrounding noise rather than just blocking it physically. In this pair, the TOZO NC3 targets a wider frequency range with its hybrid algorithm and three ANC mics on the HT2, while the Avantree E171 keeps things simpler with up to 24dB of reduction and a workout-friendly design.
