If you want to protect a Beats Powerbeats Pro charging case and carry it without worrying about knocks, dust or scratches, choose RLSOCO Carrying Case; if you need actual earbuds — a charging case that holds two different pairs for sleep, sport and calls — choose INSONIXN Earbuds. These two products only look similar because both involve a "case." One is a shell you buy to protect hardware you already own. The other is a complete audio kit with the earbuds included. That single difference decides everything below.
• RLSOCO's biggest strength: a hard EVA shell with a shock-absorbing divider and soft lining, built specifically to fit a Powerbeats Pro charging case plus its skin cover and accessories.
• RLSOCO's biggest trade-off: it is a case only. There are no earbuds, no cable and no electronics inside — buy it and you still need the Powerbeats Pro.
• INSONIXN's biggest strength: one charging case containing two complete pairs of earbuds — a semi-in-ear pair for everyday listening and an ultra-mini in-ear pair for sleep and focus — with a 30-hour total battery figure and an LED battery display.
• INSONIXN's biggest trade-off: it is a full electronics purchase with a fixed set of earbuds, so it can't be tailored to a different brand's charging case the way RLSOCO's fitted shell can.
• Buy RLSOCO if you already own Powerbeats Pro and want a compact, water-resistant travel case with a handle strap.
• Buy INSONIXN if you want the earbuds themselves and value having two fit styles in a single case.
The RLSOCO case is a purpose-built shell, not a generic pouch. It is designed around the Powerbeats Pro charging case, and it also accommodates that case with a protective skin cover still on. That detail matters more than it sounds: a lot of third-party cases only fit the bare charging case, so anyone who uses a silicone or fabric cover has to strip it off every time. RLSOCO's interior is lined in grey velvet with a shock-anti divider running down the middle, so the charging case sits snugly and doesn't rattle against anything else you drop in with it. The outer shell is hard EVA, rated water resistant, and the whole thing weighs about 0.1 kg with a handle strap for carrying it by hand.
In my opinion, this is the pick for someone who treats their Powerbeats Pro as a long-term purchase and wants a home for it. Toss it in a backpack, a gym bag or a purse and the hard shell takes the abuse instead of the charging case. The compact size and the strap make it genuinely easy to grab on the way out the door, and when you're not travelling you can just leave the earbuds stored inside — dust-free, as the design intends.
Who should skip it? Anyone who doesn't own Powerbeats Pro. The interior is tailored to that charging case and its accessories, so it won't do much for a different brand's earbuds. Skip it too if what you actually want is earbuds — this listing is the case only, and the earbuds and accessories are not included. It's also not the pick if you want a case that doubles as a charger; there's no battery here, just protection and organization.
INSONIXN takes the opposite approach. Instead of protecting earbuds you already have, it hands you two complete pairs inside one charging case. The semi-in-ear pair is the everyday set — a secure fit with 360° surround-style sound and directional audio, which suits workouts, commutes and general listening. The ultra-mini in-ear pair is the specialist: at roughly 0.1 oz per earbud, with a body designed to sit flush in the ear canal, it targets side sleepers and anyone who finds normal earbuds painful after an hour. Passive noise cancellation on that pair is a natural consequence of the deep, sealing fit rather than active circuitry.
The battery picture is straightforward. A single charge gives up to 6 hours of listening, and the 300 mAh Type-C case adds three to five more full charges for a 30-hour total. Charging the case takes about 1.5 hours. A digital LED display on the case shows the exact remaining battery level — a small thing, but far more useful than guessing from a blinking light. Bluetooth 5.4 handles the connection with a stated range of 33 feet, and the dual-device pairing lets two devices stay connected at once, so you and someone else can share the same audio.
Side-by-Side: Which Should You Choose?
• Best for protecting an existing Powerbeats Pro → RLSOCO Carrying Case. The interior is tailored to that charging case, skin cover and all.
• Best for getting earbuds in the first place → INSONIXN Earbuds. Two pairs, a charging case, a cable and a manual are in the box.
• Best for sleep and side sleeping → INSONIXN Earbuds. The 0.1 oz ultra-mini in-ear pair is explicitly designed to sit flush with no pressure.
• Best for battery life → INSONIXN Earbuds. Up to 6 hours per charge and a 30-hour total with the case, tracked on an LED display.
• Best for drop and dust protection → RLSOCO Carrying Case. Hard EVA shell, water-resistant, shock-anti divider, soft flannel lining.
• Best for sharing audio with someone else → INSONIXN Earbuds. Dual-device connection supports two paired devices at once.
• Best for carrying by hand → RLSOCO Carrying Case. The handle strap and compact body are made for grab-and-go.
• Best for a single small kit that covers the whole day → INSONIXN Earbuds. One case, two fit styles, no second purchase required.
If I had to pick one, I'd buy the INSONIXN Earbuds — because it solves a bigger problem. It gives you the earbuds, the charging case, the 30-hour battery figure, the LED display and two fit styles in one box, and it covers sleep, workouts and calls without a second purchase. I'd only choose the RLSOCO Carrying Case if I already owned Powerbeats Pro and just wanted a tough home for them; in that specific situation it's the smarter, more focused buy. Neither is "better" in the abstract — they answer different questions. Check the current price on Amazon for whichever one matches your situation, since that's the one variable I can't compare for you here.
FAQ
how to charge earbuds case
how to charge case without earbuds
With the INSONIXN case you simply connect it to a USB-C power source with the included cable and leave the earbuds out — the case charges on its own, which is handy if you want a full reserve before a trip. The digital LED display shows the case's own battery level so you know when it's done. The RLSOCO carrying case doesn't contain electronics, so this doesn't apply to it.
how to charge jlab earbuds case
I can't speak to JLab here — this comparison only covers the RLSOCO Carrying Case and the INSONIXN Earbuds, and the data I'm working from is specific to those two products. If you're cross-shopping a JLab set, check that brand's own instructions for its charging case. For the INSONIXN kit, the method is USB-C into the case.
how to charge apple earbuds case
Apple's charging cases follow their own charging method, which isn't something this comparison covers. What I can tell you is that the RLSOCO Carrying Case is designed around the Beats Powerbeats Pro charging case, not Apple's, so it won't be a tailored fit for an Apple case. If your goal is protecting an Apple charging case, this particular RLSOCO model isn't the match.
