How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a hard-shell, water-resistant home for your JBL Live Free 2 or Wave 300 that survives life at the bottom of a backpack, choose RLSOCO Case; if you need a slim, skin-friendly silicone cover for your JBL Tune 245NC with a cleaning pen and lanyard in the box, choose BOVUGAC Case.
• RLSOCO Case — biggest strength: A hard EVA and fiber shell with a water-resistant rating, RoHS/SGS-certified materials and a two-year warranty. It is built to take knocks so your charging case does not.
• RLSOCO Case — biggest trade-off: It is a bulkier, structured enclosure rather than a skin-tight cover, and it only fits JBL Live Free 2 and Wave 300 — not the Tune line.
• BOVUGAC Case — biggest strength: Premium silicone that stays slim and silky in the hand, plus a genuinely useful bundle: carabiner keychain, lanyard and a cleaning pen.
• BOVUGAC Case — biggest trade-off: Soft silicone absorbs bumps but will not match a rigid EVA shell against a hard drop, and it fits only the JBL Tune 245NC.
• Who RLSOCO Case is for: Anyone who treats their earbuds as daily commute gear and wants maximum structural protection.
• Who BOVUGAC Case is for: Anyone who wants a low-bulk cover that clips to a bag and comes with the little extras they would otherwise buy separately.
The RLSOCO Case is the more serious piece of protection in this pairing. It is a self-designed enclosure built from fiber materials and high-density EVA, and the spec sheet calls out a hard shell type with a water-resistant rating. That combination matters more than it sounds. EVA holds its shape, so the case does not collapse inward and press on the earbuds or the charging case inside. RLSOCO also states it uses a higher-grade thickness of EVA specifically so the case resists deforming over time — a real concern with cheap shells that slowly crush flat in a bag.
The material story goes further than most covers at this level. RLSOCO says the fabric, lining and EVA compartments are certified to RoHS and SGS standards, and it claims the construction resists odors, water and dust. It also ships with a two-year warranty covering manufacturing defects. Taken together, that reads like a case designed to be lived in rather than replaced every few months.
Compatibility is narrow and specific: it fits the JBL Live Free 2 and the Wave 300 TWS, and the listing is explicit that this is case only — the earbuds and accessories are not included. It also accommodates a cable and eartips, which is a small but real advantage if you like to keep a spare charging cable with your buds.
Who should skip it: If you own JBL Tune 245NC earbuds, this case will not fit at all. And if you actively dislike any added bulk and want something that feels like a second skin on the charging case, the rigid EVA build is the wrong direction for you.
BOVUGAC Case: Who It's For
The BOVUGAC Case takes the opposite approach, and it does it well. This is a soft silicone cover made specifically for the JBL Tune 245NC TWS earbuds, and the brand is clear that it is not compatible with other devices. Silicone is the right material for this job: it is described as skin-friendly and harmless, it feels silky in the hand, and it protects against scratches, accidental drops, shocks and bumps while adding essentially no bulk. For someone who drops their earbuds case into a jacket pocket and forgets about it, that slim fit is the whole point.
What sets the BOVUGAC apart is the package. You get the silicone cover, a carabiner keychain, a lanyard and a cleaning pen. The keychain is the practical standout — it lets you clip the case to a handbag, backpack or computer backpack so the earbuds are always findable instead of lost at the bottom of a bag. The cleaning pen is the kind of accessory most people never think to buy until their earbuds need it, and the lanyard gives you a second carrying option. It comes in black with a nature-style pattern.
The honest trade-off is structural. Soft silicone absorbs impact and prevents scuffs, but it does not create a rigid shell around the charging case the way EVA does. There is also no water-resistance claim here, no material certification listed, and no stated warranty. If your priority is maximum armor, this is not that product.
Who should buy it: If you own the JBL Tune 245NC and want a thin, comfortable cover that clips to your bag, with a cleaning pen and lanyard included, this is a sensible, complete little kit.
Who should skip it: If you want a hard shell, a water-resistant rating, or a warranty term you can point to, look at the RLSOCO instead — provided your earbuds are one of the two models it supports.
Side-by-Side: Which Should You Choose?
• Best for a slim, low-bulk feel → BOVUGAC Case. Soft silicone that adds no meaningful thickness.
• Best for carrying on a bag → BOVUGAC Case. Carabiner keychain plus a lanyard gives you two ways to attach it.
• Best for commuting and rough handling → RLSOCO Case. Knocks, shock and scratches are exactly what the rigid shell is built for.
• Best for accessories in the box → BOVUGAC Case. Cleaning pen and lanyard come included; RLSOCO gives you a carabiner.
• Best for a stated warranty → RLSOCO Case. Two years against manufacturing defects.
• Best for JBL Live Free 2 or Wave 300 owners → RLSOCO Case. It is the only one of the two that fits those models.
• Best for JBL Tune 245NC owners → BOVUGAC Case. Same rule in reverse — the RLSOCO will not fit.
For most people reading this, the deciding factor is not the material — it is which earbuds you own. The two cases do not overlap in compatibility, so that settles it before anything else.
That said, if I had to pick one as the stronger product on paper, I would take the RLSOCO Case. A hard EVA shell, a water-resistant rating, certified materials and a two-year warranty is a lot of engineering for a small accessory, and it is the one I would trust with earbuds that live in a backpack. If you own JBL Tune 245NC earbuds, though, my recommendation flips without hesitation to the BOVUGAC Case — it fits, it is comfortable, and the cleaning pen and lanyard make it a genuinely complete package.
