How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a two-pack of USB-C wired earbuds with MFi-certified iPhone compatibility and a long warranty, choose 1STCHAMP Apple MFi Certified; if you need a single pair with silicone tips in three sizes, a swappable fit, and a longer cable for commuting and calls, choose Tanzoizoi USB-C Noise-Cancelling.
• 1STCHAMP Apple MFi Certified — biggest strength: You get two pairs in one box, Apple MFi certification for iPhone 15/16/17 and newer, a 5-year warranty, and an in-line remote with a mic that handles volume, playback, calls and voice assistants.
• 1STCHAMP Apple MFi Certified — biggest trade-off: Fixed earbud tips (no silicone size options in the spec sheet), 140-ohm impedance that wants a decent source, and no stated cable length.
• Tanzoizoi USB-C Noise-Cancelling — biggest strength: Ergonomic in-ear design with soft silicone tips in S/M/L, a 125 cm TPE tangle-resistant cable, a built-in DAC for hi-res stereo, and an impedance of just 16 ohm that's easy to drive.
• Tanzoizoi USB-C Noise-Cancelling — biggest trade-off: One pair per box, a shorter 0.5-year warranty, and passive isolation only — it blocks ambient sound, it doesn't actively cancel it.
• Who each pick is for: 1STCHAMP if you want a spare pair, iPhone MFi peace of mind and long-term coverage; Tanzoizoi if you want one comfortable, well-fitting pair for calls, commuting and gaming.
The 1STCHAMP set is built around a simple idea: give you two identical USB-C wired earphones so you're never stuck without a pair. That's genuinely useful if you keep one at your desk and one in a bag, or if you share a phone with a partner or kid. The box contains two wired headphones, both with the same in-line remote.
That remote is the part I'd actually use daily. It handles volume, play/pause, track skipping and calls, and the microphone uses noise cancellation for voice pickup plus Siri and Google Assistant support. For driving, walking or a quick work call, that's the whole feature set you need — no unlocking your phone, no dongle, no battery to think about.
Buy 1STCHAMP if you want two pairs, you're on iPhone 15/16/17 or a Samsung Galaxy S22–S25, and you value long warranty coverage over tip customization.
Skip 1STCHAMP if you need multiple tip sizes for a secure fit, you want a longer cable, or you're plugging into a low-output source.
Tanzoizoi USB-C Noise-Cancelling: Who It's For
Tanzoizoi's pitch is comfort and fit first. The earbuds ship with soft silicone tips in small, medium and large, so you can actually dial in a seal instead of hoping one size works. A proper seal is what makes passive isolation work, and Tanzoizoi states its design blocks up to 85% of ambient sound. That's the kind of number that matters on a train, in a shared office, or while running — you hear your audio, not the room.
The cable is 125 cm and made of TPE, which resists tangling, and the housing is metal alloy. Total weight is about 25.5 g, so it disappears in a pocket or bag. The bulb is in-ear with a TPE enclosure — note the spec sheet lists the color as "Blcak," which I read as black.
Inside, a DAC chip drives hi-res stereo with what the brand describes as rich bass and clean highs, and the impedance is just 16 ohm. That low number means almost any USB-C phone, tablet or laptop can drive them easily — iPhone 15/16/17, iPad 10th Gen/Pro, Galaxy S22–S25, Pixel 2 through 8, MacBook and Galaxy Tab are all listed. The in-line mic is tuned for calls, and the push-button media controls handle volume, play/pause, track skipping and answering or ending calls. That makes them a sensible pick for Zoom meetings, online classes, mobile gaming and podcasts.
The trade-offs are real. You get one pair, not two. The warranty is 0.5 years, which is short. And despite the "noise-cancelling" name, the spec sheet describes passive isolation — no battery, no active circuitry, no ANC.
Buy Tanzoizoi if fit comfort matters most, you want a longer tangle-resistant cable, and you're plugging into a wide range of USB-C devices.
Skip Tanzoizoi if you want a backup pair in the box or you'd rather have years of warranty coverage.
• Best for getting two pairs → 1STCHAMP Apple MFi Certified (2-pack).
• Best for iPhone MFi peace of mind → 1STCHAMP Apple MFi Certified (explicit Apple MFi certification, iPhone 15/16/17 support).
• Best for long-term coverage → 1STCHAMP Apple MFi Certified (5-year warranty vs 0.5-year).
• Best for fit customization → Tanzoizoi USB-C Noise-Cancelling (silicone tips in S/M/L).
• Best for easy volume on any device → Tanzoizoi USB-C Noise-Cancelling (16 ohm impedance is far easier to drive than 140 ohm).
• Best for a longer, tangle-resistant cable → Tanzoizoi USB-C Noise-Cancelling (125 cm TPE cable, metal alloy housing).
• Best for commuting, running and noisy rooms → Tanzoizoi USB-C Noise-Cancelling (ergonomic seal, stated up to 85% ambient noise blocked).
• Best for calls across the widest device list → Tanzoizoi USB-C Noise-Cancelling (iPhone, iPad, Galaxy, Pixel, MacBook, Galaxy Tab).
• Best all-rounder if you share devices or want a spare → 1STCHAMP Apple MFi Certified.
If you're weighing value, check the current price on Amazon for both before you decide — the two-pack changes the math on 1STCHAMP, while Tanzoizoi competes on fit and cable.
In my opinion, Tanzoizoi USB-C Noise-Cancelling is the one I'd buy for myself. The reason is fit: three silicone tip sizes plus a 125 cm tangle-resistant cable and 16-ohm impedance make it the easier pair to live with across a phone, tablet and laptop, and the passive seal is the feature you'll notice most on a commute or in a call-heavy day. I'd only steer you to 1STCHAMP if you specifically want a second pair on hand or you value that 5-year warranty above everything else — for a household with multiple USB-C devices, that bundle is the smarter call.
If you want a spare set for a bag, desk or second device, yes — the box includes two identical wired earphones with the same in-line remote. If you only ever need one pair, Tanzoizoi is the simpler buy.
It's passive isolation, not active noise cancellation. Soft silicone tips create a seal that the brand says blocks up to 85% of ambient sound, which helps on trains, planes and in busy rooms, but there's no battery-powered ANC.
Both do. 1STCHAMP carries Apple MFi certification and lists iPhone 15/16/17 support, and Tanzoizoi lists the same iPhone generations plus iPad, Galaxy, Pixel, MacBook and Galaxy Tab.
Warranty and quantity versus fit and cable. 1STCHAMP gives you two pairs and a 5-year warranty; Tanzoizoi gives you one pair, three tip sizes, a 125 cm tangle-resistant cable and much lower 16-ohm impedance that's easier to drive.
