How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a self-contained pair of true wireless earbuds with a smart touchscreen case, active noise cancelling and a transparency mode, choose CNBRO Wireles; if you need a Bluetooth adapter module that turns your existing two-pin wired IEMs into TWS headphones, choose EZ EAR KBEAR BT15.
• CNBRO Wireles — biggest strength: a touchscreen charging case that doubles as a remote (calls, music, language switching, find-my-earbuds, camera shutter), plus ANC/ENC noise cancelling and a transparency mode.
• CNBRO Wireles — biggest trade-off: it's a closed ecosystem. You get the earbuds that come in the box and that's it. No swapping in your own IEMs, and it's a plastic, in-ear, white-bodied design with a 10 m Bluetooth range.
• EZ EAR KBEAR BT15 — biggest strength: it's a 2-pin Bluetooth 5.4 module with LE Audio that converts compatible wired IEMs into true wireless, with a 15 m range and roughly 6 hours per charge plus four extra recharges from the case.
• EZ EAR KBEAR BT15 — biggest trade-off: no noise cancelling at all, no touchscreen, controls are remote-based, and it is useless unless you already own a compatible 2-pin IEM.
• Pick CNBRO Wireles if you want one finished product you unbox and use, with noise cancelling and a screen on the case.
• Pick EZ EAR KBEAR BT15 if you already own (or plan to own) something like a Moondrop Chu II, Aria, Blessing, KZ ZST/AS10/ZSR/ES4, Truthear Hexa or Zero, and want to cut the cable without buying new earbuds.
The CNBRO Wireles is a complete TWS package. Bluetooth 5.3, in-ear rounded tips, balanced armature drivers, a 20 Hz–20 kHz frequency range, and a plastic enclosure in white. Everything about the design says "grab it and go" rather than "tinker with it."
What makes it interesting is the case. It's a touchscreen case, not just a battery box. From that screen you can answer calls, control music playback, switch languages, trigger a search for a misplaced earbud, and — my favourite detail — use it as a remote shutter for your phone camera. Pose, tap the screen, photo taken. No asking a stranger. That's a genuinely useful trick for solo travellers and anyone who takes a lot of self-portraits.
The audio side leans practical rather than audiophile. ANC and ENC dual noise cancellation to cut down outside noise and clean up calls, and a transparency mode so you can hear traffic around you without pulling the buds out. That transparency mode matters more than people think if you walk or cycle near roads. Battery is rated at 6 hours of single playtime and up to 20 hours with the case, with a 1.5 hour charge time.
Who should buy it: commuters, walkers, cyclists, office workers on calls, and anyone who wants noise cancelling, a screen-based control surface and a camera remote in one box. The age range listed starts at 6+, so it's also pitched at a broad household rather than a specialist listener.
Who should skip it: if you already own good wired IEMs and love their sound, this won't let you keep them. And if you want top-tier codec support or a specific tuning, a fixed earbud set is a limitation, not a feature.
The EZ EAR KBEAR BT15 is a different animal entirely. It isn't a pair of earbuds in the usual sense — it's a Bluetooth adapter module that plugs into two-pin in-ear monitors via ear hooks, so your wired IEMs become true wireless.
The spec that matters most is Bluetooth 5.4 with LE Audio support, which the manufacturer states delivers roughly 15% lower power consumption than Bluetooth 5.2. In practice that means more listening per charge. The module itself runs about 6 hours on a full charge, and the charging case adds roughly four full recharges on top. Charging takes about 6 hours, and the indicator lights tell you the state: red flashing for low power, red while charging, green when full.
Range is 15 metres, which is noticeably more headroom than the CNBRO's 10 metres — handy if you leave your phone on a desk and wander.
The design is black, in-ear, plastic, with a balanced armature driver and a shaped fit that the brand says is contoured to ear anatomy for secure wear during long sessions or workouts. No noise cancelling, no transparency mode, and controls are remote-based rather than touch-on-bud. Compatibility is the whole story here: it's built for KZ ZST/AS10/ES4/ZST-X/EDX/ZSN, Moondrop Chu 2/Aria/Blessing 3/Kato/Aria 2/Dusk, Tangzu Wan'er, Truthear x Crinacle Zero/Hexa/Zero/Nova, Kiwi Ears Cadenza and Orchestra Lite, Simgot EM6L/Supermix 4/EW200/EA500LM, and 7Hz Zero 2.
Who should buy it: anyone already invested in two-pin IEMs who wants to ditch the cable without giving up their preferred sound signature. It also suits people who own several IEMs and want one wireless module to rotate between them.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → CNBRO Wireles. ANC and ENC are built in. The BT15 has no noise control at all.
• Best for staying aware of traffic → CNBRO Wireles. Its transparency mode lets ambient sound in without removing the buds.
• Best for battery endurance → EZ EAR KBEAR BT15. Roughly 6 hours per charge plus about four full case recharges beats the CNBRO's 6 hours plus 20 total with the case.
• Best for charging speed → CNBRO Wireles. Around 1.5 hours to charge versus roughly 6 hours for the BT15 module.
• Best for wireless range → EZ EAR KBEAR BT15. 15 metres versus 10 metres.
• Best for people who already own IEMs → EZ EAR KBEAR BT15. If your Moondrop, KZ, Truthear or Simgot set is on the compatibility list, you keep the sound you already like.
• Best for control gimmicks and convenience → CNBRO Wireles. A touchscreen case that handles calls, music, language switching, earbud finding and camera shutter is a lot of utility in one place.
• Best for a first TWS purchase → CNBRO Wireles. One box, everything included, nothing to plug in or match.
In my opinion, most people reading a TWS comparison should buy the CNBRO Wireles. It's the safer, more complete purchase: noise cancelling, a transparency mode, a genuinely clever touchscreen case, and no compatibility homework required. The BT15 is the better product for a narrower, more specific buyer — someone with a drawer full of two-pin IEMs who wants to go wireless without changing how anything sounds. If that's you, the BT15 is the smarter spend. If you just want earbuds that do a lot out of the box, I'd take the CNBRO. Either way, check the current price on Amazon before deciding, since that's the one variable I can't weigh in for you.
FAQ
how to pair tws headphones
how to connect tws headphones
Switch Bluetooth on, make sure the earbuds are charged and out of the case, then pick the device name from your phone's Bluetooth menu. The CNBRO's touchscreen case also shows status, which is handy when you're not sure whether the buds have linked. If nothing shows up, move closer — the BT15 reaches about 15 metres, the CNBRO about 10.
how to reset tws headphones
Resets are model-specific, so follow the manufacturer's instructions for whichever you own. A common approach is to clear the pairing on your phone, place both buds back in the case, then re-pair from scratch. That clears stale connections and fixes most "one bud won't connect" complaints.
how to use tws headphones
Charge the case, pair once, then use the controls you actually have. On the CNBRO Wireles that means touch controls on the buds plus the case screen for calls, music, language switching and camera shutter. On the EZ EAR KBEAR BT15 it means remote controls, with the buds plugged into your own two-pin IEMs first.
