If you want to protect the charging case you already own, choose RLSOCO Carrying Case; if you need a complete pair of wireless earbuds with their own charging case, choose Ordtop Earbuds.
• RLSOCO Carrying Case — biggest strength: a hard-shell, custom-fit EVA case built specifically for Sony WF-C510 / WF-C710N / WF-C700N / WF-C500 earbuds and their charging case. Biggest trade-off: it contains no earbuds and no charging case of its own, so it is only useful if you already own one of those Sony models.
• Ordtop Earbuds — biggest strength: a full listening package, with Bluetooth 5.4 earbuds, a lightweight charging case with a dual LED power display, and up to 40 hours of combined playback. Biggest trade-off: it is a single sealed system, so if you want to keep using Sony earbuds, it is not a substitute.
• Who each pick is for — RLSOCO for Sony WF-C500-series owners who want dust, shock and water resistance in a compact hard case; Ordtop for anyone who actually needs earbuds and a charging case in one purchase.
• These two products sit in different categories, which is why the comparison keeps coming back to one word: charging case earbuds. The RLSOCO is a shell that protects a charging case you own. The Ordtop is a charging case with earbuds inside it. Knowing which side of that line you're on decides everything.
The RLSOCO case is a purpose-built shell. It is molded for the Sony WF-C510, WF-C710N, WF-C700N and WF-C500 truly wireless models, which means the fit is tight rather than generic — the earbuds and their charging case sit in dedicated compartments instead of sliding around loose. The enclosure is a hard shell made from high-density EVA combined with 1680D material and polyester fiber, and RLSOCO lists it as water resistant, dust resistant and shock resistant, with scratch-resistant properties as well.
That combination is the whole point. Most people carry earbuds loose in a bag pocket, where keys, coins and a water bottle do the damage. A dense EVA compartment absorbs impact, keeps dust off the charging contacts, and stops the lid from getting crushed. RLSOCO also states that it uses a thicker grade of EVA than typical storage cases so the case keeps its shape rather than deforming over time, and that the fabric, lining and EVA compartments carry RoHS and SGS certification. There is a two-year warranty covering manufacturing defects.
Who should buy it: owners of those specific Sony models who treat their earbuds as everyday carry and want a compact hard case that slips into a purse, pocket, backpack or handbag. The blue solid-pattern design is small enough for daily use and the hard shell means you can toss it in a bag without a second thought.
Who should skip it: anyone who does not own a WF-C500-series Sony headset — the fit is custom, not universal. And anyone shopping for earbuds themselves. This listing is case only; earbuds and accessories are not included. If you need the audio hardware, this is not the product.
The Ordtop Earbuds are the opposite kind of purchase: everything in one box. You get two wireless earbuds, a lightweight charging case, a USB-C cable and three ear cap sizes (S/M/L). The earbuds run Bluetooth 5.4 with support for HSP, HFP, A2DP and AVRCP, and Ordtop describes a 0.1s low-latency connection with automatic pairing as soon as you take them out of the case. The connection range is stated at up to 15 meters.
The audio side is built around a 13mm dynamic driver using DSR lossless HD rendering, with a large chamber acoustic design that balances internal and external air pressure. Ordtop claims the 13mm driver has roughly four times the drive area of a standard driver, which is the engineering behind the punchy bass and full midrange it advertises. For calls, the earbuds combine ENC noise cancelling microphones — four HD mics in total — so your voice is picked out and processed in real time. This is passive noise cancellation, not active, so it reduces outside sound through fit and sealing rather than electronic cancellation.
Battery is where this set stands out. Ordtop rates each earbud at 8 hours of playback on a single charge, and the charging case adds four full recharges for up to 40 hours total. A dual LED display on the case shows the charge status of both the earbuds and the case itself, and the Type-C port is there for faster, safer charging.
Around that you get the practical stuff: IP7 nano-coating that protects the internal components from sweat and liquid, a curved shape designed to follow the ear canal so they stay put during runs and gym sessions, touch controls for play/pause, track skipping, volume, calls and voice assistant, and compatibility with iOS, Android, TVs, laptops and computers. Total weight is 35 grams. Ordtop backs it with a one-year warranty.
Who should buy it: anyone who wants earbuds and a charging case in a single purchase, especially people who train, commute or take calls on the move. Who should skip it: Sony owners who are happy with their current earbuds and only want protection — the Ordtop set would be a redundant second pair.
• Best for protecting an existing charging case → RLSOCO Carrying Case. Custom-molded for Sony WF-C500-series earbuds, with a hard EVA shell.
• Best for battery life → Ordtop Earbuds. 8 hours per charge and up to 40 hours total with the charging case.

• Best for calls and voice clarity → Ordtop Earbuds. Four HD microphones with ENC noise cancelling.
• Best for workouts and sweaty sessions → Ordtop Earbuds. IP7 nano-coating plus a curved, ear-canal-shaped fit.
• Best for charging convenience → Ordtop Earbuds. Dual LED power display and Type-C charging.
• Best for keeping your bag organized → RLSOCO Carrying Case. Compact, hard-sided and pocket sized.
• Best for a single all-in purchase → Ordtop Earbuds. Two earbuds, the case, a cable and three ear cap sizes are in the box.
In my opinion, the smarter buy depends entirely on what is missing from your setup. If you already own a Sony WF-C500-series headset, I would buy the RLSOCO Carrying Case — a hard, custom-fit shell with a two-year warranty is cheap insurance for a charging case you'd rather not replace. If you don't own earbuds yet, I would buy the Ordtop Earbuds instead. Bluetooth 5.4, a 13mm driver, four mics, IP7 protection and up to 40 hours with the case cover the whole job in one purchase. My pick for most readers starting from zero: Ordtop Earbuds.
FAQ
how to charge earbuds case
how to charge case without earbuds
A charging case charges independently of the earbuds. Plug the USB-C cable into the case and a power source, and the case's internal battery fills up whether or not the buds are inside — the Ordtop case's LED panel lets you check that status directly.
how to charge jlab earbuds case
That depends on the specific JLab model, so check its manual rather than assuming. The general pattern is the same as the Ordtop system: the earbuds charge from the case, and the case charges over its own cable.
how to charge apple earbuds case
Apple's cases use their own charging method, so follow Apple's guidance for your model. The principle is unchanged from the Ordtop setup: the case holds the reserve power, the earbuds draw from it, and the case is refilled separately.
