• Seadream Silicone Case — biggest strength: a two-pack (one black, one white) in soft, skin-friendly silicone with a 360° full-coverage claim, a charging-port dust plug and a metal carabiner.
• Seadream Silicone Case — biggest trade-off: it is cut specifically for the JBL Tune 130NC TWS and nothing else, so it is useless if you own a different model.
• BOVUGAC Case — biggest strength: a single black silicone sleeve matched to the JBL Tune 245NC, bundled with a keychain, a cleaning pen and a lanyard.
• BOVUGAC Case — biggest trade-off: one case only, no colour choice, and it is locked to the 245NC fit.
• Who Seadream is for: JBL Tune 130NC owners who want a spare cover, a colour swap and a clip-on carry loop.
• Who BOVUGAC is for: JBL Tune 245NC owners who want one tidy case plus the small extras that keep earbuds clean and tethered.
The Seadream Silicone Case is a straightforward protective skin for the JBL Tune 130NC TWS. It is made from soft silicone rubber, which the spec sheet describes as skin-friendly, odourless, lightweight, dust-proof, shockproof and waterproof. In practice that means a cover that absorbs the everyday stuff — a knock against a doorframe, a slide across a desk, keys rattling around in the same bag pocket. The material is also listed as anti-slip and heavy-duty in protection terms, so it adds grip without turning the case into a brick.
The detail I like most here is the charging-port dust plug. If you have ever pulled a cheap TWS case out of a jacket pocket and found lint packed into the charging opening, you know why that matters. Seadream also states the cover does not interfere with wireless charging and that you can charge from the bottom without removing it, which is the practical test any silicone sleeve has to pass. A metal carabiner clip is included, so you can hang the whole thing off a handbag or backpack strap instead of burying it loose in a pocket.
Then there is the two-pack. You get one black and one white cover, which is genuinely useful: keep one on the case, keep the other as a spare or swap colours to match what you are carrying. Item weight is listed at 0.05 kg, so it is a featherweight addition. Installation is described as easy, and there is a one-year warranty description on the listing.
Who should buy it: JBL Tune 130NC TWS owners who want full-coverage silicone, a dust plug over the charging port, a clip for carrying, and the flexibility of two covers. Who should skip it: anyone who does not own the Tune 130NC — this is a model-specific fit, and it will not stretch onto other earbuds. If you want a cleaning tool or a lanyard in the box, this is not the package that includes them.
The BOVUGAC Case takes a slightly different approach. It is designed specifically for the JBL Tune 245NC TWS and, according to the spec sheet, is not compatible with other devices. That is worth taking literally — this is a fitted sleeve, not a universal pouch. The material is premium silicone, described as skin-friendly and harmless, with a silky feel in the hand, and it claims full protection from scratches, accidental drops, shocks and bumps without adding bulk. The slim-fit, soft-shell framing tells you the design intent: keep the profile low so the earbuds still slip into a jeans pocket.
Where BOVUGAC differentiates is the bundle. Alongside the black case cover you get a carabiner keychain, a cleaning pen and a lanyard. That is a small but thoughtful kit. The cleaning pen is the piece most people never think to buy until the mesh and crevices of a TWS case get grimy — and on budget earbuds, keeping the charging contacts and speaker openings clear is exactly the kind of maintenance that keeps them working properly. The lanyard and keychain give you two ways to attach the case, whether that is a handbag, a backpack or a computer bag.
The pattern is listed as "nature" and the colour is black only, so if you wanted a colour option, this is not the pick. It is also a single case rather than a pair.
Who should buy it: JBL Tune 245NC TWS owners who want one slim, silky silicone cover and value having a cleaning pen and lanyard included rather than buying them separately. Who should skip it: anyone with a JBL Tune 130NC or any non-245NC model, and anyone who wants two covers or a colour choice.
• Best for JBL Tune 130NC TWS → Seadream Silicone Case, which is cut for that model only.
• Best for JBL Tune 245NC TWS → BOVUGAC Case, likewise a model-specific fit.
• Best for charging-port protection → Seadream, thanks to its dust plug design over the port.
• Best for keeping the earbuds clean → BOVUGAC, because the cleaning pen is part of the package.
• Best for carrying options → BOVUGAC, which supplies a keychain, a lanyard and a carabiner-style clip.
• Best for a spare or a colour swap → Seadream, since you get two covers, one black and one white.
• Best for a low-bulk pocket feel → BOVUGAC, described as a slim-fit soft shell that adds no bulk.
• Best for wireless-charging convenience → Seadream, which states the cover does not affect wireless charging and allows bottom charging without removal.
In my opinion, the deciding factor here is not the case at all — it is which earbuds you own. If you have the JBL Tune 130NC TWS, I would buy the Seadream Silicone Case: the dust plug, the two-pack and the stated wireless-charging compatibility make it the more practical everyday cover. If you have the JBL Tune 245NC TWS, I would buy the BOVUGAC Case, because the cleaning pen and lanyard give it more value in one box than a bare sleeve would. Neither is a universal product, so check your model number before you order.
what is tws earbuds
TWS stands for "true wireless stereo" — earbuds that connect to your phone with no cable between the two buds and no wire to the device. The JBL Tune 130NC and Tune 245NC referenced here are both TWS models, which is why each cover is fitted to one specific charging case shape.
what is tws earbuds means
It means the left and right earbuds each have their own wireless connection and their own battery, syncing with each other rather than being joined by a wire. That is also why the charging case matters so much: it is the only thing keeping those small buds charged, which is exactly what these silicone covers are protecting.

That varies enormously by brand and model, and this page does not quote prices. For the covers themselves, check the current price on Amazon using the button on this page — the figures change, and I would rather you see the live number than a stale one from me.
how to tws earbuds
Pairing is normally the same routine: take both buds out of the case, put them in your ears, and let them enter pairing mode, then select them in your phone's Bluetooth menu. Once paired, they reconnect automatically when you remove them from the case — which is another reason a snug, protective cover like these two is worth having.
