If you want true wireless earbuds with an integrated charging case, long battery life and a secure ear-hook fit, choose Caykist Earbuds 96H; if you need a protective hard-shell travel case for a pair of JBL Endurance Peak 3 earbuds you already own, choose RLSOCO Case. These two products are not really rivals — one is a complete earbud system, the other is a storage shell. But shoppers searching for "charging case earbuds" land on both, so let's sort out which one actually belongs in your bag.
• Caykist Earbuds 96H — biggest strength: A complete wireless earbud setup with a dual-LED charging case, 96-hour battery claim, Bluetooth 5.4 and IPX7 waterproofing, all in one box.
• Caykist Earbuds 96H — biggest trade-off: It's a sport-focused over-ear hook design with push-button controls, so it won't suit anyone who wants touch controls or a discreet in-ear look.
• RLSOCO Case — biggest strength: A custom-molded EVA hard shell with a velvet lining, mesh accessory pocket and metal hook that protects a JBL Endurance Peak 3 charging case from bumps, shocks and crushes.
• RLSOCO Case — biggest trade-off: It's a case only — no earbuds, no charging case, no cable inside. Without JBL Endurance Peak 3 earbuds, it has nothing to hold.
• Who Caykist Earbuds 96H is for: Anyone who wants a ready-to-use sport earbud with a charging case built in.
• Who RLSOCO Case is for: Someone who already owns JBL Endurance Peak 3 earbuds and wants to protect the charging case while travelling.
The Caykist Earbuds 96H is what most people mean when they say "charging case earbuds." The charging case is part of the product, not an add-on. It has a Type-C port, refills in about 1.5 hours, and carries a dual LED display: the left side tracks the case's own remaining power, the right side shows the charging progress of each earbud. That's a genuinely useful detail — you can see at a glance whether the case itself needs topping up, rather than guessing.
On the audio side, the spec sheet lists a 13.9mm dynamic driver, a cavity acoustic design meant to balance internal and external air pressure, and ENC noise cancellation on the microphone for calls. Bluetooth 5.4 handles the wireless link with a stable range of up to about 33 feet, and pairing is one-step: connect once, and the buds auto-pair the next time you open the case. Controls are physical push buttons on each earbud, and both sides can be operated independently — play/pause, track skip, volume, calls and voice assistant.
The fit is the other headline. These are over-ear hook buds with a silicone enclosure, curved ear hooks and an ergonomic shape designed to stay put during jogging, gym work and yoga. IPX7 waterproofing with a nano-coating keeps sweat and splashes out. Caykist also notes they're dust and water-drop resistant but not meant for heavy rain or rinsing under a tap — good to know before you treat them as fully submersible.
Who should buy it: Runners, gym-goers and anyone who wants one purchase that covers earbuds, charging case, cable and three ear-tip sizes in the box. Who should skip it: If you dislike ear hooks, want touch controls, or prefer a case-free design, this isn't your pick.
The RLSOCO Case is a different animal entirely. It is made specifically for the JBL Endurance Peak 3 true wireless earbuds and their accessories — and it is sold as the case only. No earbuds, no charging case, no charging cable included. If you don't already own JBL Endurance Peak 3 buds, this product has no job to do.
What it does, it does with intent. The shell is high-density EVA with polyester fabric and a soft velvet lining, built to shield the earbuds and their charging case from bumps, shocks and crushes. It resists water and dust, which matters when the case lives at the bottom of a gym bag or gets stuffed into a backpack pocket. Inside, the top cover has a mesh pocket for cables and small accessories, while the bottom holds the earbuds — keeping the two separated and organised instead of tangled together.
There's also a tongue strap inside to help lift the headphones out of the case, which is a small thing that becomes a big thing when your fingers are cold or your hands are full. Carrying is handled by a compact footprint — roughly 4.13 x 3.15 x 2.17 inches and about 0.06 kg — plus a metal hook that clips onto a backpack. RLSOCO states the fabric, lining and EVA compartments are certified to RoHS/SGS standards, uses a thicker grade of EVA so the case resists deforming, and backs it with a two-year warranty.

The RLSOCO Case is the better buy only in one specific situation — you already own JBL Endurance Peak 3 earbuds and want to stop your charging case from getting crushed in a bag. If that's you, it's a well-considered shell. If it isn't, it solves a problem you don't have yet.
FAQ
how to charge earbuds case
how to charge case without earbuds
A charging case can be topped up on its own — just connect it to power with the earbuds removed. The case holds its own battery, so charging it without the buds inside simply refills the case's reserve. The Caykist Earbuds 96H's left-hand LED readout is dedicated to the case's own power level, so you can watch that reserve fill up even when the earbuds aren't in it.
how to charge jlab earbuds case
JBL earbud charging cases generally recharge through their own charging port once the earbuds are seated inside. Because charging behaviour is model-specific, follow the instructions that came with your JBL Endurance Peak 3 earbuds. If you're protecting that case on the move, the RLSOCO Case is moulded for the Endurance Peak 3 and stores the earbuds and charging case together.
