If you want to restore the fit and comfort of your JBL Vibe 100 TWS earbuds with fresh silicone tips in three sizes, choose ALXCD Ear Tips Compatible; if you need to protect a pair of JBL Tune 230NC TWS earbuds and carry them without losing them, choose BOVUGAC Case.
• ALXCD Ear Tips Compatible — biggest strength: six pairs of soft silicone replacement tips in small, medium and large, made specifically for the JBL Vibe 100 TWS, so you can dial in the seal and comfort that stock tips often fail to deliver.
• ALXCD Ear Tips Compatible — biggest trade-off: it is a consumable accessory, not a case. It does nothing for protection, carrying or storage, and it only fits the JBL Vibe 100 TWS.
• BOVUGAC Case — biggest strength: a soft silicone shell built for the JBL Tune 230NC TWS, bundled with a carabiner keychain, a lanyard and a cleaning pen, so your earbuds stay clipped to a bag and free of scratches.
• BOVUGAC Case — biggest trade-off: it adds a layer around the charging case and is strictly shaped for the Tune 230NC TWS — it will not fit other models, and the earbuds themselves are not included.
• Who each pick is for: ALXCD for anyone whose JBL Vibe 100 TWS tips are worn, torn or simply uncomfortable; BOVUGAC for anyone who owns JBL Tune 230NC TWS and keeps losing or scratching the case.
This is a maintenance product, and it solves a very specific annoyance. The ALXCD kit is built around the JBL Vibe 100 TWS, and it ships as six pairs of soft silicone earbud tips in small, medium and large. That mix matters more than it sounds. Silicone tips are the part of an earbud that actually touches your ear, and they are also the part that flattens, hardens and eventually tears with daily use. When that happens, the earbuds themselves are usually fine — the seal is not. Replacing the tips restores the fit without replacing the headphones.
Who should buy it: anyone with JBL Vibe 100 TWS earbuds who finds the original tips uncomfortable, loose, or simply worn out, and anyone who wants a cheap insurance policy against losing the seal mid-workout. Who should skip it: anyone who does not own the JBL Vibe 100 TWS. These tips are made to that model's nozzle, and this is not a universal-fit kit. Also skip it if what you actually need is protection or a way to carry the charging case — that is a different product entirely, and this kit does not address it.
BOVUGAC Case: Who It's For
The BOVUGAC Case is a protective shell for the JBL Tune 230NC TWS charging case, and it is cut specifically to that model. The silicone is described as skin-friendly and soft, with a silky feel in the hand, and the point of it is straightforward: it absorbs the scratches, bumps and accidental drops that a bare plastic charging case collects over months of living in a pocket or at the bottom of a bag. It is also slim, so it does not turn a pocketable case into a brick.
What makes this bundle more useful than a plain cover is what comes with it. You get the case cover, a carabiner keychain, a lanyard and a cleaning pen. The keychain is the standout. Clipping the earbuds case to a backpack strap or handbag means you stop digging for it, and it is genuinely harder to lose something that is physically attached to your bag. The cleaning pen addresses the other slow killer of true wireless earbuds — earwax and dust in the earbud mesh and the charging contacts.
Side-by-Side: Which Should You Choose?
• Best for worn or uncomfortable ear tips → ALXCD Ear Tips Compatible. Six pairs in S/M/L is the fix for a bad seal.
• Best for drop, bump and scratch protection → BOVUGAC Case. The soft silicone shell is the whole point of the product.
• Best for not losing your earbuds → BOVUGAC Case. The carabiner keychain and lanyard let you clip the case to a bag.
• Best for keeping earbuds clean → BOVUGAC Case. The included cleaning pen handles wax and dust around the mesh and contacts.
• Best for fit customization → ALXCD Ear Tips Compatible. Three sizes let you run different tips in each ear and keep spares.
• Best for JBL Vibe 100 TWS owners → ALXCD Ear Tips Compatible. That is the model it is made for.
• Best for JBL Tune 230NC TWS owners → BOVUGAC Case. Same logic, opposite product.
• Best for a low-effort upgrade you can forget about → either. Both are simple accessories; neither changes how the earbuds sound.
If I owned JBL Vibe 100 TWS earbuds and the tips were the problem, I would buy the ALXCD Ear Tips Compatible kit. Six pairs across three sizes is the most direct way to fix comfort and seal, and spares mean you are covered the next time a tip tears. If I owned JBL Tune 230NC TWS earbuds and carried them daily, I would buy the BOVUGAC Case — the keychain, lanyard and cleaning pen do more real-world work than the cover alone. These are not competitors; they solve different problems for different models. Buy the one that matches the earbuds in your pocket.
how to connect tws headphones
Put the earbuds in the charging case, open the lid, and take them out — most true wireless models, including the JBL Vibe 100 TWS and Tune 230NC TWS, power on and enter pairing mode automatically. Then open your phone's Bluetooth settings, find the model name in the list and select it. If they do not appear, put them back in the case for a few seconds and try again.
how to pair tws headphones
Pairing means connecting the earbuds to a specific device for the first time, and the process is the same as connecting: remove them from the case so they enter pairing mode, then select them in your phone's Bluetooth menu. Once paired, most phones reconnect automatically the next time the earbuds power on. If you are pairing to a second device, you usually need to disconnect from the first one.
how to use tws headphones
Charge the case first, then take the earbuds out — they switch on automatically. Insert them with the tip seated comfortably in your ear; if the seal feels loose, that is exactly when a replacement tip set like the ALXCD kit becomes useful. Playback, calls and volume are normally controlled by tapping the earbud touch panels, and the exact tap commands are set by the manufacturer.
how to reset tws headphones
A reset clears old pairings and is the standard fix when one earbud stops connecting. The usual method is to place both earbuds in the case, then press and hold the case button (or the earbud touch panels) for several seconds until the indicator light flashes. Because the exact timing varies by model, check your JBL model's instructions before resetting. After a reset, pair the earbuds again from your phone's Bluetooth menu.
