• Aptkdoe Earbuds 75H — biggest strength: Up to 75 hours of total playtime from the charging case, with 15 hours on a single charge, plus IPX7 water resistance and TPU ear hooks built for running and gym work.
• Aptkdoe Earbuds 75H — biggest trade-off: It is a complete in-ear headphone, so it is the more involved purchase — you get the earbuds, ear tips and case, but no separate hard shell, and the color is a single fixed Cosmic Orange.
• RLSOCO Hard Case — biggest strength: A compact, water-resistant, dust-resistant hard EVA shell designed to absorb knocks, shocks and scratches for your existing earbuds and charging cable.
• RLSOCO Hard Case — biggest trade-off: It is a case only — no earbuds, no charging cable and no accessories are included, and it is sized for the Anker Soundcore Liberty 5 Pro / Liberty 5 Pro Max rather than for any brand.
• Who each pick is for: Buyers who still need earbuds → Aptkdoe Earbuds 75H. Buyers who already own Liberty 5 Pro earbuds and want to protect them → RLSOCO Hard Case.
The Aptkdoe HD65 is a sport-focused set of true wireless earbuds, and the headline number is battery. Aptkdoe rates it at up to 15 hours of continuous listening on a single charge, with the charging case adding enough top-ups for roughly 75 hours of total playtime. The case itself carries a dual LED display that shows the remaining power of the case and the charging progress of the buds, and a Type-C port refills the case in about 1.5 hours. For anyone who charges on a Sunday night and then forgets about it, that combination is genuinely convenient — you can see exactly what is left rather than guessing from a blinking light.
The fit story is where this model earns its place. The ear hooks are made from an elastic TPU material, which solves the classic problem of buds working loose mid-run, and the material is described as comfortable and anti-allergic. Add nano-coated IPX7 waterproofing and you have a pair that shrugs off sweat and raindrops during jogging, gym sessions and yoga. The 14.2 mm dynamic driver covers a 20 Hz–20,000 Hz range at 32 ohm impedance, so the tuning leans toward deep bass with a mellow midrange — a sensible choice for workout playlists. Calls get help from ENC noise reduction mics that passively cut background noise so both sides of a conversation come through more clearly.
On the control side, Aptkdoe uses physical push buttons rather than touch panels. You can play, pause, skip tracks, adjust volume, answer or end calls and trigger voice assistance without pulling out your phone. In my opinion that is the right call for sport use — buttons behave predictably when your hands are sweaty or gloved, and they don't misfire the way touch sensors can. Bluetooth 5.4 handles pairing with HFP, A2DP, HSP and AVRCP support, a stable range up to about 33 feet, and instant reconnection the moment you open the case. The package includes three pairs of ear tips in small, medium and large, a USB-C cable, and a two-year warranty.
Who should buy it: runners, gym-goers, cyclists and anyone who wants one pair of earbuds for workouts and daily listening without worrying about battery level or rain. Who should skip it: anyone who already owns the Anker Soundcore Liberty 5 Pro and only needs a case, or anyone who prefers touch controls and a more neutral, reference-style sound signature over bass-forward tuning.
This is a single-purpose product, and it's worth being blunt about that: the RLSOCO case is a protective shell, not a pair of earbuds. It is designed to fit the Anker Soundcore Liberty 5 Pro and Liberty 5 Pro Max wireless earbuds along with their charging cable and other small accessories. If you own those earbuds and you've been carrying them loose in a bag or pocket, this is the missing piece.
The construction is what justifies it. RLSOCO uses a fiber outer material with high-density EVA foam compartments, and the company states the fabric, lining and EVA are certified to RoHS and SGS standards. The EVA is deliberately a higher grade and thickness than typical, which matters because thin foam shells deform over time and stop hugging the contents. The case is rated water resistant and dust resistant, and its job is straightforward: absorb knocks, shock and scratches so your charging case and earbuds arrive intact. At roughly 3.11 x 3.03 x 1.97 inches, it's compact enough to drop into a purse, pocket, backpack or handbag without becoming a brick.
The color is a solid purple, and the form factor is a hard shell case. It carries a two-year warranty. One thing to be very clear about — the listing is case only. Earbuds, charging cable and accessories are not included, so this is not a purchase that gets you listening to music on its own.
Who should buy it: Liberty 5 Pro or Liberty 5 Pro Max owners who travel, commute or carry their earbuds in a bag and want hard-shell protection. Who should skip it: anyone who doesn't own those specific Anker earbuds, anyone who needs actual earbuds, and anyone who prefers a soft pouch over a rigid shell.
• Best for battery life → Aptkdoe Earbuds 75H. Up to 15 hours per charge and roughly 75 hours total, with a dual LED display showing real percentages.
• Best for gym, running and sweaty workouts → Aptkdoe Earbuds 75H. IPX7 nano-coated waterproofing plus elastic TPU ear hooks designed to stop the buds falling out.
• Best for protecting earbuds you already own → RLSOCO Hard Case. Hard EVA shell, water- and dust-resistant, built to take knocks and scratches.
• Best for travel and bag carry → RLSOCO Hard Case. About 3.11 x 3.03 x 1.97 inches, compact enough for a pocket or backpack, with room for a charging cable.
• Best for clear calls on the move → Aptkdoe Earbuds 75H. ENC noise reduction mics passively cut background noise so both sides of the call come through more clearly.
• Best for glove-friendly, no-look control → Aptkdoe Earbuds 75H. Physical push buttons for play, volume, tracks and calls instead of a touch surface.
• Best for wide device compatibility → Aptkdoe Earbuds 75H. Bluetooth 5.4 with HFP, A2DP, HSP and AVRCP, pairing with phones, tablets and laptops.
• Best for a complete out-of-the-box setup → Aptkdoe Earbuds 75H. Earbuds, charging case, USB-C cable and three sizes of ear tips are all included; the RLSOCO case ships empty.
If I had to pick one, I'd buy the Aptkdoe Earbuds 75H. It's the product that actually does something — it plays music, lasts through a week of workouts between charges, survives sweat and rain, and comes with everything you need in the box. In my opinion it's the right choice for the majority of shoppers landing on this comparison, because most people searching for earbuds still need earbuds. The RLSOCO Hard Case is a genuinely well-made accessory and I'd recommend it without hesitation to anyone who already owns Anker Soundcore Liberty 5 Pro or Liberty 5 Pro Max buds and wants to stop them rattling around unprotected. But it's a complement, not a substitute.
FAQ
I don't list prices here, and they change often. Check the current price on Amazon using the button on this page for both the Aptkdoe earbuds and the RLSOCO case.
No. The RLSOCO case is designed for the Anker Soundcore Liberty 5 Pro and Liberty 5 Pro Max, and it's shaped around that charging case. The Aptkdoe HD65 comes with its own charging case, so it doesn't need one.
The IPX7 nano-coated waterproofing is aimed at sweat and raindrops, and the TPU ear hooks are designed to keep the buds in place while you move. For heavy downpours or swimming, I'd still treat them as splash-resistant sport earbuds rather than fully submersible gear.
