How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete, do-everything pair of earbuds with touchscreen controls, active noise cancelling and a 60-hour battery, choose CuiSuto Earbuds; if you need a rugged, eco-certified hard shell to protect an existing pair of Anker Soundcore Liberty 5 Pro or Liberty 5 Pro Max earbuds, choose the RLSOCO Hard Case.
These two products sit in totally different aisles, and that's the first thing to get straight before anyone talks you into a "which is better" argument. One is a full audio product. The other is a storage shell that doesn't play a single note. So the real question isn't which one wins — it's which one your situation actually calls for.
• CuiSuto Earbuds — biggest strength: A smart touchscreen charging case that handles volume, track skipping, calls and even earbud location without touching your phone, backed by true ANC, 5 EQ modes and up to 60 hours of playtime.
• CuiSuto Earbuds — biggest trade-off: It's a single sealed system. You get the earbuds, the case, the controls and the sound all in one package, so you're committing to the whole thing rather than upgrading pieces. It's also designed around in-ear fit, not over-ear comfort.
• RLSOCO Hard Case — biggest strength: A hard-shell, water-resistant, dust-resistant, scratch-resistant home for your earbuds and charging cable, with RoHS/SGS-certified materials and a two-year warranty.
• RLSOCO Hard Case — biggest trade-off: It is case only. No earbuds, no cable, no charging brick. And it's built specifically around the Anker Soundcore Liberty 5 Pro / Liberty 5 Pro Max shape.
• Who each is for: CuiSuto for the person who needs earbuds today. RLSOCO for the person who already owns Liberty 5 Pro or Pro Max earbuds and wants them to survive a backpack.
The headline feature here is the smart multifunctional touchscreen charging case. Instead of digging your phone out of a pocket to change volume or skip a track, you do it on the case itself. You can also manage calls and locate your earbuds from that screen. In my opinion, that's the single most interesting thing about this product, because it changes the little friction points of daily listening rather than just adding another spec to a box.
The physical side matters too. Each earbud weighs 0.13 oz, which is light enough that you'll forget you're wearing them during a long work session. The stem design with a metallic finish keeps them looking sharp, and the sweat- and dust-resistant build means gym sessions, runs and commutes aren't a problem. The case is pocket-sized by design.
Who should buy it: anyone who wants one purchase that covers noise cancelling, long battery life, sport-friendly durability and phone-free control. Students, commuters, gym-goers and people on calls all fit here. It works with iPhone and Android over Bluetooth, and there's no headphone jack — it's wireless only.
Who should skip it: if you already own a pair of earbuds you love and just want to protect them, buying a second set of earbuds is wasted money. And if you prefer over-ear headphones or a wired connection, this isn't your category.
RLSOCO Hard Case: Who It's For
Let's be blunt about what this is: a protective shell. RLSOCO built it specifically for the Anker Soundcore Liberty 5 Pro and Liberty 5 Pro Max, plus room for charging cables and small accessories. The earbuds and accessories are not included. If you don't own those specific earbuds, this case isn't for you — the fit is designed around them.
What it does well is protection. The shell is hard, the enclosure material is polyester, and the construction uses fiber materials combined with high-density EVA. RLSOCO states the EVA is a higher-grade thickness than typical storage cases specifically so the shape doesn't deform easily. The case is rated water-resistant, dust-resistant and scratch-resistant, so knocks, shocks and scratches are the things it's actually engineered to absorb. It measures 3.11 x 3.03 x 1.97 inches, which is compact enough to drop into a purse, backpack, handbag or a larger pocket.
Two details stand out to me. First, the materials are described as eco-friendly and certified by RoHS/SGS across the fabric, lining and EVA compartments — that's a concrete claim about what's in the product rather than vague marketing language. Second, it comes with a two-year warranty. For a case, that's a meaningful signal about how long the maker expects it to hold up. It also comes in purple, which is a small thing but worth knowing if you're matching gear.
Who should buy it: Liberty 5 Pro or Liberty 5 Pro Max owners who carry their earbuds in a bag, toss them in a car, or travel with them and want them arriving intact. Also anyone who's had a soft pouch fail on them before.
Who should skip it: everyone else. If your earbuds aren't the Liberty 5 Pro or Pro Max, or if you only ever leave your earbuds on a desk at home, this is protection you don't need. And remember — it protects a charging case, it doesn't replace one.
• Best for phone-free control → CuiSuto Earbuds. The touchscreen case handles volume, tracks, calls and earbud location without your phone.
• Best for blocking out noise → CuiSuto Earbuds. True ANC with four adjustable modes is a core feature here; the RLSOCO case has no electronics at all.
• Best for long listening sessions → CuiSuto Earbuds. Up to 60 hours of playtime and 0.13 oz per earbud are built for all-day wear.
• Best for workouts → CuiSuto Earbuds. Sweat- and dust-resistant build, light weight and an ergonomic in-ear fit suit running and gym use.
• Best for protecting earbuds you already own → RLSOCO Hard Case. Hard shell, water-resistant, dust-resistant and scratch-resistant.
• Best for travel and bag carry → RLSOCO Hard Case. At roughly 3.11 x 3.03 x 1.97 inches it slips into a backpack or purse and absorbs knocks.
• Best for lasting material quality → RLSOCO Hard Case. RoHS/SGS-certified fabric, lining and EVA, plus a two-year warranty.
• Best overall value for someone starting from zero → CuiSuto Earbuds. One purchase covers sound, noise cancelling, controls and battery.
Notice the pattern: these aren't competitors. They solve different problems, and the only real overlap is that both are things you'd own alongside a phone.
My Verdict
If I had to buy one, I'd buy the CuiSuto Earbuds. In my opinion, it's the product that stands on its own — ANC, Bluetooth 5.4, 13mm drivers, 5 EQ modes, a touchscreen case and 60 hours of playtime is a genuinely complete package, and it's the one that works the moment it arrives. The RLSOCO Hard Case is a good accessory, not a rival. If you already own Liberty 5 Pro or Pro Max earbuds and you're hard on your gear, buy the case too. But if you're choosing one thing today, the earbuds do far more.
No. CuiSuto Earbuds are actual wireless earbuds with ANC, Bluetooth 5.4 and a touchscreen charging case. The RLSOCO Hard Case is a protective storage shell only — no earbuds, no cable, no electronics.
It isn't designed for them. RLSOCO states compatibility with the Anker Soundcore Liberty 5 Pro and Liberty 5 Pro Max, and the interior is shaped around those earbuds and their charging case. Don't assume a universal fit.
Yes. The charging case is part of the product and includes the touchscreen controls, and the package also includes a USB-C charging cable and user manual. That's different from the RLSOCO case, which is sold as case only.
Depends on what you're missing. If you need earbuds, check the CuiSuto listing. If you already own Liberty 5 Pro or Pro Max earbuds and need protection, check the RLSOCO listing. Prices change, so check the current price on Amazon before deciding.
