How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired audio-and-charging solution that keeps a 3.5mm headphone jack alive on modern Samsung phones, choose HopePow 2; if you need fully wireless listening with long battery life and a waterproof build, choose Jxrev Earbuds. These two products solve completely different problems, so the "better" one is simply the one that matches how you actually use your phone.
• HopePow 2's biggest strength: it's a 2-in-1 USB-C adapter that lets you plug in wired 3.5mm headphones and charge your Samsung phone at the same time — something a plain dongle can't do.
• HopePow 2's biggest trade-off: it's a passive accessory, not a listening device. It only helps if you already own wired headphones and a compatible Samsung Galaxy.
• Jxrev Earbuds' biggest strength: a genuine all-in-one audio package — Bluetooth 5.4, 50 hours of total playtime, ENC call noise reduction, dual LED battery display and IP7 waterproofing.
• Jxrev Earbuds' biggest trade-off: like all true wireless buds, they carry a charging routine and a small risk of losing an earbud — no cable to keep them tethered.
• Who each pick is for: HopePow 2 is for the wired-headphone loyalist who refuses to give up their 3.5mm cans; Jxrev Earbuds are for the commuter, gym-goer or traveler who wants everything wireless.
The HopePow 2 isn't a pair of earbuds at all — it's a USB Type-C to 3.5mm headphone and charger adapter. That single sentence tells you almost everything. If you've moved to a recent Samsung Galaxy and discovered your favorite wired headphones no longer have a home, this little black nylon-finished dongle is the bridge back. The "2-in-1" design is the real selling point: a standard adapter forces you to pick between listening and charging, while this one splits the single USB-C port into both functions simultaneously.
What it does best is remove a specific, annoying compromise. Picture a long flight or a marathon work-from-home day where you want to wear your trusty over-ear headphones and keep the phone topped up. A basic dongle makes you choose. This one doesn't. The nylon finish also suggests it's built to survive being tossed in a bag pocket, and at roughly 5 grams it adds essentially nothing to your carry.
Who should buy it? Anyone with a compatible Samsung Galaxy — the listing names the S26 Ultra, S26, S25 Ultra, S25, S24, and the A-series models like A17, A57, A37, A27 and A16 — who owns wired 3.5mm headphones and wants to keep using them without juggling two dongles. It's also a smart pickup for someone who takes calls on a wired headset and doesn't want the battery to die mid-conversation.
Jxrev Earbuds: Who It's For
The Jxrev Earbuds are the opposite kind of purchase: a complete listening system in a charging case. The headline spec is Bluetooth 5.4, which Jxrev frames as a 2026-generation chip with faster audio data transmission, improved connection stability and lower power draw. In practical terms, that means fewer dropouts when you walk away from your phone and a connection that holds up in crowded places where older Bluetooth can stutter — the kind of everyday reliability that matters more than any single number on a spec sheet.
Sound and calls are handled by 14mm dynamic drivers paired with four ENC (environmental noise cancelling) microphones. The mics are tuned to reduce background noise and echo during calls, which is the feature you'll actually notice on a windy street or a noisy café. The sound signature leans toward deep bass with clear mids and bright treble — a fun, energetic tuning rather than a flat studio one. Note the audio driver is listed at 13mm in the item details while the feature copy says 14mm; either way, it's a large driver for buds this size and the intent is clearly bass-forward.
The practical stuff is where these really earn their place. You get up to 8 hours on a single charge and 50 hours total with the case, a 1-hour full recharge over USB-C, and a dual LED display that shows the remaining power of both the buds and the case — a genuinely useful touch that ends the "are these about to die?" guessing game. Each bud weighs just 3 grams, and three sizes of silicone tips (S, M, L) help you find a secure fit. IP7 waterproofing means sweat and rain are non-issues, which is why these suit running, workouts and travel.
Who should buy them? Commuters, gym-goers, runners and travelers who want one small case to cover music, calls and workouts. The touch controls handle play/pause, calls, volume, track switching and voice assistants, and pairing is a one-step affair — pop both buds out and they connect to each other automatically. Anyone on Android or iOS is covered.
Who should skip them? If you're a wired-headphone purist who hates charging another device, or you want the guaranteed-latency-free connection only a cable provides for critical listening, true wireless may frustrate you. And if you simply need to revive the headphone jack on a Samsung phone, these don't help at all — they're wireless only, with no jack of their own.
• Best for keeping wired headphones alive → HopePow 2. It's the only one of the two that gives you a 3.5mm jack.
• Best for listening and charging at the same time → HopePow 2. The 2-in-1 split is its whole reason to exist.
• Best for battery life → Jxrev Earbuds. Up to 8 hours per charge and 50 hours total with the case.
• Best for workouts and rain → Jxrev Earbuds. IP7 waterproofing and a 3g-per-bud fit built for movement.
• Best for clear calls on the move → Jxrev Earbuds. Four ENC mics reduce environmental noise and echo.
• Best for a zero-maintenance, no-charging accessory → HopePow 2. No plug, no battery, nothing to remember.
• Best for someone who owns no wired headphones → Jxrev Earbuds. Buying the adapter without wired cans makes no sense.
• Best for a recent Samsung Galaxy owner with a drawer full of old headphones → HopePow 2. That's precisely the buyer it targets.
In my opinion, these aren't really competitors — they're answers to two different questions, and you should buy whichever question is yours. If I had a compatible Samsung Galaxy and a beloved pair of wired headphones, I'd buy the HopePow 2, because it solves a problem no wireless earbud can: it keeps your existing gear working while your phone charges. If I wanted one device for music, calls, workouts and travel with no cables at all, I'd buy the Jxrev Earbuds — the 50-hour battery, ENC mics and IP7 rating make them the more complete everyday package. For most people who just want to listen wirelessly, Jxrev is the pick; for the wired holdout, HopePow 2 is the fix.
No. It's a USB Type-C to 3.5mm headphone and charger adapter. It lets you connect wired headphones and charge a compatible Samsung phone at the same time — it doesn't play audio on its own.
Yes. Jxrev states they're compatible with almost all Bluetooth-enabled devices, including iOS and Android phones and tablets, so either platform works.
The Jxrev Earbuds. Their IP7 waterproofing, 3g-per-bud weight and three sizes of silicone tips are designed for sweat, rain and secure movement. The HopePow 2 is a passive adapter with no water-resistance claim.
