How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight, sleep-friendly earbud with app-based sound tuning, choose TOZO A1; if you need marathon battery life and a secure hook that survives sweaty workouts, choose HAOYUYAN Earbuds.
• TOZO A1's biggest strength: a genuinely tiny 3.7g-per-bud in-ear design with 32 EQ presets in the TOZO app, so you can reshape the sound to taste.
• TOZO A1's biggest trade-off: no ear hooks and no active noise cancellation — it's built for comfort and fit, not for lockdown during hard training.
• HAOYUYAN Earbuds' biggest strength: a claimed 70mAh-per-bud battery (8 hours) plus a 600mAh case, which adds up to roughly 90 hours of total playback with an external LED display.
• HAOYUYAN Earbuds' biggest trade-off: it's a bigger, hook-style over-ear design with no companion app, so you're stuck with the factory tuning and no EQ customization.
• Buy the TOZO A1 if you have smaller ears, want something you can lie on, and care about tuning your sound.
• Buy the HAOYUYAN Earbuds if you run, lift, or ride, and battery anxiety is your main enemy.
The TOZO A1 is a study in minimalism. Each earbud weighs 3.7 grams, and the whole product is aimed squarely at people whose ears are too small for the average bud. The in-ear, round-shaped housing sits flush, which means side-sleepers can realistically wear one to bed without a hard edge digging into the pillow. That's a specific, narrow use case, and TOZO clearly built for it.
Sound-wise, you get a 6mm dynamic driver with 16 ohm impedance and a 20Hz frequency response — modest hardware on paper, but TOZO pairs it with its own OrigX tuning, which the spec sheet describes as emphasizing clear vocals and balanced mids. The real differentiator is the app: 32 EQ presets, plus access to a larger library of user-shared EQ profiles. If you like fiddling with bass and vocal balance, this is the more flexible of the two by a wide margin.
Battery is 7 hours per charge and up to 32 hours total with the case, charged via USB-C in about 2 hours. Bluetooth 5.3 handles pairing and a 20-meter range, and the ENC microphones are tuned to reduce traffic and office noise on calls. Latency is listed at 60ms, which is fine for video but not a gaming-grade figure.
Who should skip it: anyone who needs ear hooks for sprinting, or who wants active noise cancellation. TOZO lists noise control as "None" — the seal is your only isolation.
HAOYUYAN Earbuds: Who It's For
The HAOYUYAN T16 goes the opposite direction: it's a sports-first bud. Instead of a flush in-ear fit, it uses elastic, soft ear hooks that wrap over the ear, and it ships with three sizes of ear tips. That combination is the whole pitch — it stays put when you're moving. The IPX7 rating backs it up, meaning it handles sweat and splashes rather than just surviving a light drizzle.
Audio hardware is actually larger here: a 14.2mm dynamic driver versus the 6mm unit in the TOZO. Bigger drivers generally move more air, and HAOYUYAN describes the tuning as well-balanced with a snug fit that helps filter noise on calls. Note that the noise control listed is passive — the physical seal does the work, not electronics. There's no app, no EQ presets, no touch customization beyond the standard controls.
The headline number is battery. Each bud carries a 70mAh cell for up to 8 hours of continuous use at moderate volume, and the 600mAh charging case pushes total playback to roughly 90 hours. An external digital LED display on the case shows the level without opening the lid — a small thing that's genuinely useful when you're packing for a trip.
One spec worth flagging: the product info lists the model number as T17 while the model name is T16, and the warranty is described as 90 days manufacturer coverage. Controls are button/touch-based rather than app-driven.
Who should buy it: runners, gym-goers, cyclists, and anyone who wants to charge once and forget about it for a week.
Who should skip it: people with small ears who dislike hooks, and anyone who wants to tune their own sound signature. There's no app to do it with.
Side-by-Side: Which Should You Choose?
• Best for small ears → TOZO A1. A 3.7g bud with a compact, flush in-ear shape is the entire design brief.
• Best for sleeping or side-lying → TOZO A1. No hard edges and a low profile make it the only realistic option here.
• Best for workouts and running → HAOYUYAN Earbuds. Ear hooks plus IPX7 plus three tip sizes equals a fit that doesn't shift.
• Best for sound customization → TOZO A1. 32 EQ presets in the app, versus fixed tuning on the HAOYUYAN.
• Best for bigger drivers → HAOYUYAN Earbuds. 14.2mm versus 6mm — if you equate driver size with fuller low-end, this is the one.
• Best for calls in noisy places → TOZO A1. ENC microphones are explicitly designed to cut traffic and office noise.
• Best for travel convenience → HAOYUYAN Earbuds. The external LED battery display means you check power without opening the case.
• Best for iPhone/Android/PC flexibility → HAOYUYAN Earbuds. Bluetooth 5.3 with broad compatibility across phones, tablets, laptops, and smart TVs.
In my opinion, most people shopping this comparison should buy the HAOYUYAN Earbuds. The 90-hour total playback, ear-hook stability, and IPX7 rating cover the three things that actually annoy earbud owners: dead batteries, buds falling out, and sweat damage. I'd only steer you to the TOZO A1 if small ears or side-sleeping is your specific problem — that's where it has no real competition between these two. If you're torn, ask yourself one question: do you wear buds while moving, or while lying still? The answer picks your product.
FAQ
HAOYUYAN, on paper. The elastic ear hooks, three ear-tip sizes, and IPX7 waterproofing are all aimed at movement and sweat. The TOZO A1 relies on its in-ear seal alone and carries an IPX5 rating, which is splash-resistant but not the same class.
TOZO A1: 7 hours per bud, up to 32 hours with the case, and about 2 hours to recharge. HAOYUYAN: 8 hours per bud and roughly 90 hours total with the case. The HAOYUYAN wins this one comfortably.
No. TOZO lists noise control as "None" — it uses ENC microphones to clean up your voice on calls, not to cancel sound around you. The HAOYUYAN uses passive noise cancellation, which just means the ear-tip seal blocks some outside sound.
It depends on what you want. The HAOYUYAN has the larger 14.2mm driver; the TOZO A1 pairs a 6mm driver with OrigX tuning and 32 EQ presets you can adjust in the app. If you like tuning your own sound, I'd lean TOZO. If you want a set-and-forget signature with more driver surface, HAOYUYAN is the pick. Check the current price on Amazon before you commit — that's the one variable that can flip this decision.
