How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a purpose-built, hard-shell organizer made specifically for the JBL Endurance Peak 3 and its charging case, choose RLSOCO Case; if you need a lightweight, water-resistant IEM pouch that swallows earbuds, cables, tips and small everyday gear, choose KB EAR CCZ Taichi. These two accessories get lumped together because both are "earbud cases," but they solve completely different problems. One is a fitted travel shield for a single charging case. The other is a soft, sealed catch-all for wired IEMs and loose accessories. Pick based on what you actually carry, not on the category label.
• RLSOCO Case — biggest strength: Custom-molded interior for the JBL Endurance Peak 3 charging case, with a mesh pocket, a tongue strap to lift the earbuds out, and a hard EVA shell.
• RLSOCO Case — biggest trade-off: It's built around one specific earbud model, so it's the wrong buy if you switch between several pairs or mostly carry wired IEMs.
• KB EAR CCZ Taichi — biggest strength: Wide compatibility and a sealed TPU build that holds IEMs, cables, eartips, memory cards and small valuables in one place.
• KB EAR CCZ Taichi — biggest trade-off: No molded fit, no cable pocket, and no lift strap — it's a flexible pouch, not a fitted hard case.
• Who RLSOCO Case is for: JBL Endurance Peak 3 owners who want their charging case protected and their cable kept separate.
• Who KB EAR CCZ Taichi is for: IEM users and travelers who want one compact, water-resistant organizer for a mix of small gear.
The RLSOCO Case is a fitted storage case, not a generic pouch. It's made specifically for the JBL Endurance Peak 3 True Wireless Active Earbuds, and the interior is laid out with that in mind: the bottom cover holds your earbuds and their charging case, while the top cover has a mesh pocket for cables and small accessories. That separation matters more than it sounds. Charging case in one half, cable in the other, nothing tangled.
The materials point to protection rather than pure storage. High-density EVA and polyester fiber with a soft velvet lining form a hard shell that resists water and dust and guards the charging case against bumps, shocks and crushes. The interior tongue strap lifts the earbuds out so you're not digging around with your fingers. Outside, it's compact enough for a pocket, backpack or handbag, and there's a metal hook for clipping it to a bag. It measures 4.13 x 3.15 x 2.17 inches and weighs 0.06 kg, so it's small but genuinely rigid. RLSOCO also notes the fabric, lining and EVA compartments are certified by RoHS/SGS, uses a thicker grade of EVA to resist deformation, and backs the case with a two-year warranty.
Buy this one if you own the JBL Endurance Peak 3 and want the charging case shielded during travel and commutes. Skip it if you rotate between different earbuds, since the fit is model-specific — and remember it's the case only; earbuds and accessories aren't included.
The CCZ Taichi is a portable IEM case with a very different philosophy: broad compatibility over a fitted interior. KB EAR lists it as suitable for KZ ZS10 PRO, ZS12 PRO X, ZST, EDX PRO and CASTOR, CCA CRA, KBEAR KS1 and STORM, CCZ MELODY, plus headphone cables, eartips, charging cables, memory cards, flash drives, keys, watches and jewelry. That's a wide net. If you own wired IEMs and a tangle of loose accessories, this pouch is designed to hold all of it.
Protection comes from a sealed TPU design that keeps out moisture and dust, paired with a PE lining that KB EAR describes as elastic and cushioning to reduce the impact of external forces on whatever's inside. The shell type is listed as hard, so it's not a floppy sleeve — but it's a bag form factor, not a molded tray. It weighs just 15 g, which is the headline number here: this thing practically disappears in a travel bag, storage bag or on a belt via the fixed rope. There are four color options — white, gray, transparent black and black.
Buy it if you want one lightweight organizer for IEMs plus small odds and ends, or if you travel and need a compact sealed pouch. Skip it if you specifically want a molded home for a JBL Endurance Peak 3 charging case, or if you want a dedicated cable pocket and a lift strap.
• Best for a fitted, molded interior → RLSOCO Case. The bottom holds your earbuds and charging case; the top mesh pocket keeps the cable separate.
• Best for wide compatibility → KB EAR CCZ Taichi. It's rated to hold a long list of IEM models plus cables, tips, cards and small valuables.
• Best for travel protection of a charging case → RLSOCO Case. High-density EVA, polyester fiber and a velvet lining give it a rigid, water- and dust-resistant shell.
• Best for minimal carry weight → KB EAR CCZ Taichi. At 15 g, it's the lighter option by a wide margin.
• Best for everyday pocket or bag carry → RLSOCO Case. Compact dimensions plus a metal hook for clipping onto a backpack.
• Best for loose gear and clutter control → KB EAR CCZ Taichi. The sealed TPU build and PE lining keep small items tidy and cushioned.
• Best for easy earbud retrieval → RLSOCO Case. The interior tongue strap lifts the earbuds out instead of forcing you to fish for them.
• Best for long-term durability confidence → RLSOCO Case. Thicker EVA to resist deformation and a two-year warranty versus a one-year warranty on the Taichi.
In my opinion, the RLSOCO Case is the better buy if you own the JBL Endurance Peak 3. The custom fit, the molded separation of earbuds and cable, the lift strap and the two-year warranty all add up to a case that does one job properly. The CCZ Taichi is the smarter pick if your collection is broader — wired IEMs, spare tips, memory cards, a watch — or if weight is your priority. If you're torn, ask yourself one question: am I protecting one specific charging case, or organizing a pile of small gear? Your answer decides it. Either way, check the current price on Amazon before you commit, since both sit in the budget-accessory range and the numbers move.
how to charge earbuds case
Put the earbuds back in their charging case, close the lid, then connect the case to a power source using its charging cable. For the JBL Endurance Peak 3, the RLSOCO Case's mesh pocket is there to keep that cable separate from the earbuds, so you always know where it is.
how to charge case without earbuds
You can plug the charging case in with the earbuds removed — the case itself charges independently. Just be aware that the case won't be topping up the earbuds at the same time, so you'll still need to seat them back in the case later to charge them.
how to charge jlab earbuds case
JLab cases typically charge via their own cable, and the same habit applies across brands: keep the cable and the case together so you're never hunting for one without the other. A case with a dedicated cable pocket, like the RLSOCO design, makes that routine much easier to stick to.
how to charge apple earbuds case
Apple's AirPods cases charge over their own cable or a wireless pad, and they're small and easy to lose. If you also carry wired IEMs or loose accessories, a compact pouch like the KB EAR CCZ Taichi is a practical way to keep a charging cable and small extras in one sealed, dust-resistant spot.
