If you want one pair of Bluetooth headphones that covers noise canceling, a real transparency mode and a companion app that helps you keep track of them, choose Coby Noise-Canceling Earbuds w/Charging; if you need the smallest possible earbuds with a touchscreen charging case you can run without your phone, choose Ttbesmi Touch Screen Invisible.
• Coby's biggest strength: three listening modes (active noise canceling, transparency, normal), a USB-C charging case, Bluetooth auto pairing and the Coby Smart app for EQ and GPS earbud tracking.
• Coby's biggest trade-off: the listed battery average life is 8 hours, and you need your phone nearby for app features like EQ and mode cycling.
• Ttbesmi's biggest strength: a smart charging case with its own touchscreen for volume, EQ, battery levels, time and alarms — plus a genuinely tiny 0.1 oz earbud made for small ear canals.
• Ttbesmi's biggest trade-off: the earbuds themselves last only 7 hours, and the "invisible" sizing that suits small ears may not suit everyone.
• Pick Coby if you want app control, tracking and a longer single-charge spec.
• Pick Ttbesmi if you want discreet earbuds for work and a case that works as a standalone control hub.
The Coby earbuds are built around three switchable modes: active noise canceling, transparency and normal. That trio matters if you're the kind of listener who moves between environments — blocking out a commute, then flipping to transparency so you can hear a platform announcement or a barista calling your order, then back to normal. Transparency mode is the one people underestimate: it's the difference between pulling an earbud out every five minutes and simply hearing the world around you.
Everything else is aimed at daily-driver convenience. Bluetooth auto pairing means after the first setup you just drop them in and they connect. The touch controls handle play/pause, skipping tracks and answering calls without reaching for your phone. The case charges over USB-C, which is the same cable you probably already carry for everything else, and the spec sheet lists 8 hours of battery average life — enough for a workday or a long travel leg on a single charge.
The Coby Smart app is where this pair separates itself. In the app you can cycle through the noise canceling modes, adjust the EQ to your taste and track the earbuds via GPS if they go missing. A 20 Hz to 20,000 Hz dynamic driver covers the full audible range, and Bluetooth range is listed at 10 meters.
Who should buy it? Anyone who wants a straightforward, app-supported pair for commuting, working or traveling, and anyone who has lost earbuds before and likes the idea of tracking them. Who should skip it? Shoppers who specifically need ultra-small buds for narrow ear canals, or who want to control everything from the case itself without opening an app. If price is your deciding factor, check the current price on Amazon before you commit.
Ttbesmi's pitch is unusual and specific: the charging case has its own touchscreen. From that screen you can control earbud settings, volume, EQ modes and battery levels for both the buds and the case, plus see the time and set alarms — all without taking out your phone. If you've ever wanted to leave your phone in a locker, a bag or another room and still manage your audio, that's the point of this design.
The earbuds themselves are the other half of the story. Each bud weighs about 0.1 oz and the shape is a rounded tip, built for small ear canals and for staying visually discreet — Ttbesmi describes them as invisible and hardly noticeable at work. For anyone whose ears reject standard-size buds, that's a real design decision rather than a marketing line.
Audio and connectivity hold up on paper: Bluetooth 5.4, a dynamic driver, and a carbon fiber composite diaphragm paired with large dynamic acoustic technology for stereo imaging. There's also a TF card slot, so the case can act as an MP3 player — you can run with music and no phone at all. Battery is split between the two parts: 7 hours in the earbuds plus 12 hours in the case for up to 20 hours total, with a one-hour quick recharge on the case. You also get active noise canceling and a transparent mode you can trigger by touch or from the case.
Who should buy it? Small-eared listeners, people who want discreet buds at work, and anyone who likes the idea of a phone-free control center. Who should skip it? Buyers who need a single-charge spec longer than 7 hours in the buds, or who'd rather manage everything from a phone app.
Side-by-Side: Which Should You Choose?
• Best for controlling everything without your phone → Ttbesmi, whose touchscreen case handles volume, EQ, battery levels, time and alarms.
• Best single-charge battery spec → Coby at 8 hours per the battery average life figure.
• Best total battery with the case → Ttbesmi at up to 20 hours (7 in the buds plus 12 in the case).
• Best for small ear canals → Ttbesmi, with 0.1 oz buds designed for small ears and discreet wear.
• Best for finding lost earbuds → Coby, thanks to GPS tracking in the Coby Smart app.
• Best for phone-free listening while running → Ttbesmi, which plays from a TF card like an MP3 player.
• Best for app-based sound tuning → Coby, with its EQ customizer.
In my opinion, Coby Noise-Canceling Earbuds w/Charging is the safer buy for most people. The combination of three listening modes, transparency on demand, auto pairing, a longer 8-hour single-charge figure and an app that both tunes your sound and helps you find the buds covers more everyday situations. I'd only steer you to Ttbesmi Touch Screen Invisible if small, discreet buds and a case-first control experience are your top priorities — that's a narrower but very real need, and it's the one thing Coby doesn't try to solve.
Transparency mode isn't exclusive to Apple — it's a feature across many brands. Both pairs here include it: Coby lists transparency as one of three modes alongside noise canceling and normal, and Ttbesmi offers a transparent mode you can switch on by touch or from the charging case.
Do all AirPods have transparency mode?
No, not every model in any lineup carries every feature, so it varies by generation. The practical takeaway for this comparison is that transparency is a mode, not a given — check the spec list, and note that both the Coby and Ttbesmi earbuds here list it explicitly.
Any headphone that pipes outside sound in through its microphones while you keep it on. In this matchup, Coby covers it as one of three selectable modes, and Ttbesmi lets you enter transparent mode so you can hear airline or subway announcements without removing the buds.
On Apple models it's usually a press-and-hold on the stem or a swipe in Control Center, depending on the generation. On these two pairs the method differs: Coby cycles modes through the Coby Smart app or its touch controls, while Ttbesmi switches transparency on by finger touch or from the charging case screen.
