• APETOO's biggest strength: a built-in DAC chip and USB-C plug, so it delivers digital audio directly to iPhone 15/16/17, iPad, MacBook, Samsung Galaxy, Pixel and more — no adapter, no app.
• APETOO's biggest trade-off: the 45° half in-ear shape deliberately doesn't seal your ear canal, so it won't block outside noise and won't give you thumping isolation.
• KASOTT's biggest strength: a gaming-tuned in-ear with a 10 mm dynamic driver, a 45° angled fit, three eartip sizes and an in-line remote with three quick-action buttons including mute.
• KASOTT's biggest trade-off: it's a 3.5 mm wired earphone only. There's no USB-C option, so a phone without a headphone jack needs an adapter.
• Pick APETOO if you live on a USB-C device and want clear calls, music and light gaming without dongles.
• Pick KASOTT if your priority is console or PC gaming and you want an in-ear that seals, stays put, and has a mute button.
The APETOO USB C Headphones are, at their core, a compatibility play. The spec sheet lists a long run of USB-C devices: iPhone 15/16/17 family, iPhone 16e and Air, iPad Pro and iPad Air (M4), iPad 10th gen, iPad mini 6 and 7, MacBook Air and Pro, Samsung Galaxy S26 down to S20, Note 20 Ultra, Galaxy A-series, Z Fold and Z Flip, Google Pixel 10 down to older Pixels, OnePlus, Huawei Mate and more. If your bag is a mix of a new iPhone, an iPad and a MacBook, that's exactly the mess this earbud is built to clean up. You plug in, you're done. No dongle, no Bluetooth pairing dance, no app.
Under the hood there's a digital-to-analog converter on board, which is why a USB-C iPhone actually works here — the earbuds handle the conversion themselves. The driver is a 10 mm dynamic driver at 32 ohm impedance, and the design uses a 45° half in-ear bud shape rather than a deep-sealing in-ear tip. In plain terms: you get a wider-feeling presentation than a sealed in-ear and you stay aware of traffic, a coworker, a flight announcement. The trade-off is real and worth saying out loud — you're not getting noise isolation, you're getting "sound isolation" in the soft sense. On a loud train, you'll hear the train.
Controls are on the in-line remote: volume up and down, play/pause, skip, answer and reject calls, and a voice assistant trigger. There's a microphone in the right bud for calls. The build is ABS, TPE, aluminium and copper, the whole thing weighs about 5 g, and it ships with a hard plastic carry case plus a pair of wing-covers to help the fit. It comes in pink — that's the only color listed, so don't buy it expecting a stealth black option.
KASOTT SoundMaster Pro V1: Who It's For
The KASOTT SoundMaster Pro V1 is aimed at a completely different buyer: the gamer. The pitch in its spec sheet is all about presence and localization — a 10 mm dynamic speaker tuned so that explosions, footsteps, gunshots and character voices land in a three-dimensional space rather than as a flat wall of sound. That "sense of localization" language is the classic gaming-earphone claim, and it's the whole reason this product exists. If you play anything where hearing which direction an enemy is coming from matters, that's the design goal.
The fit story is where KASOTT clearly put thought in. The earbuds use a 45° inclined in-ear design and ship with three eartip sizes — small, medium and large — so you can actually match your ear canal instead of accepting whatever tip the factory glued on. That matters more than people think: a proper seal is what gives an in-ear its bass and its isolation. The flexible material is described as reducing the ear pain that comes from long sessions, and the aim is to cut the weight and heat that over-ear gaming headsets are famous for. If you've ever taken off a headset after three hours and found a warm red ring around your ears, that's the problem this is solving.
The in-line remote has three quick-action buttons for volume and mute, and it's listed as compatible with iOS and Android devices in addition to the console and PC use in the title. The jack is 3.5 mm, the enclosure is aluminium, and the color is Flaming Red — a loud, deliberate choice. Warranty is listed at two years. One thing to be clear about: there is no USB-C option and no DAC here, so a USB-C-only phone will need an adapter, and the spec sheet lists no active noise cancellation — the isolation you get comes purely from the in-ear seal.
Buy it if: you game on Xbox Series, Xbox One, PS5, PS4, Switch or PC, you want an in-ear with a mute button and a proper seal, and you like the idea of ditching a bulky headset. Skip it if: you need USB-C, or you want something you can wear sealed for hours while also needing to hear the world.

In my opinion, the deciding question here isn't sound quality — it's what you're plugging into. If your daily driver is a USB-C phone, tablet or laptop, I'd buy the APETOO USB C Headphones, because the on-board DAC and the sheer device list mean it just works, and the half in-ear shape is genuinely better for calls, commutes and staying aware. If you're a console or PC gamer who wants an in-ear with a mute button and a proper seal, I'd buy the KASOTT SoundMaster Pro V1 instead. Two different jobs, two different answers — and neither one is the wrong pick if you match it to your device.
FAQ
Yes. The spec sheet lists iPhone 15, 16 and 17 in all their Pro, Pro Max, Plus and e variants, plus iPhone 16e and Air. The built-in DAC is what makes the USB-C connection work.
Not directly. It's a 3.5 mm wired earphone, so a USB-C-only phone would need a 3.5 mm adapter. It's designed first for Xbox Series, Xbox One, PS5, PS4, Switch and PC.
Neither has active noise cancellation. The APETOO uses a half in-ear shape that lets outside sound in on purpose; the KASOTT relies on the seal from its three eartip sizes, and its spec sheet lists no noise control.
If your gaming is on a console or PC and your phone has a headphone jack, the KASOTT's mute button and sealed fit suit it. If your gaming and calls are on a USB-C phone or tablet, the APETOO's DAC, mic and in-line remote make it the more practical single pair.
