If you want fresh silicone ear tips that keep a pair of JBL Tune 230 NC TWS earbuds comfortable and stable, choose kwmobile 6X; if you need a full set of true wireless earbuds with a touchscreen charging case and active noise cancelling, choose CNBRO Wireles.
• kwmobile 6X — biggest strength: a three-size silicone tip set made specifically for the JBL Tune 230 NC TWS / T230NC, so you can restore fit and comfort on earbuds you already own.
• kwmobile 6X — biggest trade-off: it is an accessory, not a headphone. No drivers, no battery, no Bluetooth, no noise cancelling.
• CNBRO Wireles — biggest strength: a complete TWS package with Bluetooth 5.3, ANC plus ENC, a transparency mode and a smart touchscreen charging case.
• CNBRO Wireles — biggest trade-off: single-charge playtime is quoted at up to 6 hours with the case taking you to roughly 20 hours, which is modest next to many modern earbuds, and everything runs through touch controls rather than buttons.
• Who each pick is for: kwmobile 6X for JBL Tune 230 NC / T230NC owners whose tips are lost, worn or uncomfortable; CNBRO Wireles for someone buying a whole new pair of earbuds who wants an on-case screen and noise cancelling.
kwmobile 6X is a replacement ear tip kit, and it should be judged as one. It comes in three sizes, is made from flexible silicone and is listed as compatible with the JBL Tune 230 NC TWS / T230NC. That compatibility line is the whole point: this is not a universal tip that happens to sort of fit, it is aimed at one specific family of earbuds.
What it does best is the unglamorous stuff. Silicone tips are the part of an in-ear headphone that actually touches you, and when they harden, tear or go missing, the earbuds suddenly feel loose or sound thin because the seal is gone. Swapping in fresh tips is the cheap fix. The listing describes a secure fit for home, commuting, work and on the go, and that matches how tips behave in practice: a good seal holds the earbud in place and keeps bass from leaking away. The soft silicone is also pitched at long listening sessions — music, podcasts and everyday calls — where hard or badly shaped tips get uncomfortable after an hour.
Fitting is deliberately simple: pull the old tips off, push the new ones on. The one thing worth doing before you buy is checking the shape of your original tips, because the listing itself flags that, and nozzle shapes vary between models even inside the same brand.
CNBRO Wireles: Who It's For
CNBRO Wireles is the opposite kind of product: a self-contained pair of true wireless earbuds built around a charging case with a screen. The spec sheet reads like a feature list aimed at people who like to fiddle and control things from the case rather than the phone. Bluetooth 5.3 with a quoted 10-metre range covers the normal walk-away-from-your-phone scenario, and the audio side is listed with a balanced armature driver covering 20Hz to 20,000Hz.
The headline trick is the touchscreen case. From it you can answer calls, control music, switch languages, search for the earbuds if one goes missing, and trigger the camera shutter for photos — the "pose and tap" remote-shutter idea, which is genuinely handy if you take a lot of solo photos or group shots without a tripod. Controls on the earbuds themselves are touch-based, and the noise control is active noise cancelling.
On noise, CNBRO lists two systems. ANC handles steady background noise so you get a quieter bubble for music. ENC is the call-side technology, aimed at keeping your voice clear to the person on the other end. There is also a transparency mode that lets surrounding sound in without removing the earbuds, which is the mode you would use walking near traffic or crossing a road — the listing frames it explicitly as a safety feature, and that is the sensible way to use it.
Battery is where you should set expectations. Single playtime is quoted at up to 6 hours, with up to 20 hours using the case, and the average life figure given is 5 hours. Charging the case takes about 1.5 hours. Those are workable numbers for commutes, gym sessions and desk use, but they are not all-day figures, and heavy users will be reaching for the case during the day.
Buy CNBRO Wireles if you want one purchase that gives you earbuds, noise cancelling, a transparency mode and a screen-driven control hub, and if you like the idea of managing calls and photos from the case. Skip it if you want maximum battery per charge or you prefer physical buttons over touch. The case is plastic, the earbuds sit in-ear with rounded tips, and the package is listed as two items.
• Best for replacing worn or lost tips → kwmobile 6X. Three sizes, silicone, made for JBL Tune 230 NC TWS / T230NC.
• Best for a complete listening setup → CNBRO Wireles. It is the only one of the two that actually plays audio.
• Best for noise cancelling → CNBRO Wireles. ANC for you, ENC for call clarity, plus a transparency mode.
• Best for battery life → CNBRO Wireles, with the caveat that up to 6 hours per charge and up to 20 hours with the case is moderate, not exceptional.
• Best for control flexibility → CNBRO Wireles. Touchscreen case for calls, music, language switching, finding earbuds and camera shutter, plus touch controls on the buds.
• Best for keeping earbuds comfortable for long sessions → kwmobile 6X, if you own the matching JBL model. Soft silicone is the whole design here.
• Best for low-effort, low-risk purchase → kwmobile 6X. No charging, no pairing, no firmware, no learning curve — just fit and listen.
• Best for travel and commuting → CNBRO Wireles, thanks to Bluetooth 5.3, ANC and the 10-metre range; kwmobile 6X only helps if you are already carrying JBL Tune 230 NC earbuds.
In my opinion these two products are not really rivals, so the honest recommendation depends on what you already own. If you have JBL Tune 230 NC TWS / T230NC earbuds and the fit has gone slack or a tip has vanished, I would buy kwmobile 6X — it is the targeted, specific fix and there is nothing to configure. If you are starting from nothing and want earbuds, I would buy CNBRO Wireles, because it is the only option here that gives you sound, ANC, a transparency mode and a screen-based control case in one box. Just go in expecting roughly 5 to 6 hours per charge rather than a full day.
FAQ
how to pair tws headphones
Take both earbuds out of the charging case so they power on and link to each other, then open your phone's Bluetooth settings, wait for the earbud name to appear and select it. On the CNBRO Wireles, Bluetooth 5.3 handles the connection with a quoted range of about 10 metres. After the first pairing, most phones reconnect automatically when you take the buds out again.
Connecting is the same first-time step as pairing: enable Bluetooth on your device, put the earbuds in pairing mode by removing them from the case, and pick them from the list of available devices. Once connected, playback and calls route through the earbuds automatically. If a second device needs them, disconnect from the first before pairing again, since true wireless earbuds typically hold one active connection at a time.
how to use tws headphones
CNBRO Wireles is controlled by touch on the earbuds and by the touchscreen on the charging case, where you can answer calls, control music, switch languages, locate the earbuds and trigger the camera. The transparency mode lets outside sound in without removing the earbuds, which is the setting to use near traffic, while ANC shuts background noise out. kwmobile 6X has no controls at all — it is a set of silicone tips you fit onto compatible JBL Tune 230 NC TWS / T230NC earbuds.
how to reset tws headphones
A reset normally means clearing the earbuds' stored pairings so they forget old devices and start fresh. The usual approach is to put both earbuds back in the case, then follow the reset sequence for that specific model — so check the instructions supplied with your CNBRO Wireles earbuds before trying anything. After a reset, delete the old entry in your phone's Bluetooth list and pair again from scratch.
