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, ready-to-use pair of true wireless earbuds with active noise cancelling, a 26-hour battery system and a splashproof build for workouts, choose JVC Gumy; if you need a single right-side replacement bud to revive a Samsung Galaxy Buds2 set you already own, choose wusheation Single Right Ear. These two products solve completely different problems, and that is the whole story here. One is a full kit you unbox and start using. The other is a repair part for a very specific pair of earbuds. Get that distinction right and the decision takes about ten seconds.
• JVC Gumy — biggest strength: a complete true wireless package with Active Noise Cancelling, Ambient Sound Mode, Bluetooth 5.4, IPX4 splashproofing and 26 hours of total battery life.
• JVC Gumy — biggest trade-off: it is a full set, so you are buying everything new rather than patching what you already have, and the IPX4 rating handles sweat and light rain but not full submersion.
• wusheation Single Right Ear — biggest strength: it replaces one lost or broken right earbud for Galaxy Buds2 owners without forcing them to buy a whole new pair, and it keeps ANC and the original charging case.
• wusheation Single Right Ear — biggest trade-off: it only makes sense if you already own Galaxy Buds2 (model SM-R177). For anyone else, it is the wrong product entirely.
• Choose JVC Gumy if you are starting fresh or replacing a dead pair and want noise cancelling, long battery life and a secure fit in one purchase.
• Choose wusheation Single Right Ear if you own Galaxy Buds2, you lost or broke the right side, and you want to keep using the case and the left bud you already have.
The Gumy Premium is a proper standalone true wireless set, and the spec sheet reads like JVC built it for people who wear earbuds all day. Active Noise Cancelling handles the obvious offenders — office chatter, traffic, the drone of a coffee shop — and Ambient Sound Mode flips you back to awareness when you need to hear a name called or a conversation. That toggle matters more than people expect. It is the difference between earbuds you take out constantly and earbuds you leave in.
Battery is the headline number: 6 hours per charge, 20 more from the case, 26 total, with a 2-hour charge time for both the buds and the case. The case itself carries an 18-hour average life, which lines up with the 20-hour top-up claim. Bluetooth 5.4 with a 10-meter range keeps the connection stable, and the low-latency gaming mode kills audio delay for competitive games and video streaming. Add IPX4 splashproofing, four ear tip sizes (S/M/L/XL) and an ergonomic stem design, and you have a pair built for running, gym sessions and long calls — the 3.04-ounce total weight and lightweight build are aimed squarely at preventing ear fatigue.
Who should buy it: anyone who wants one purchase that covers commuting, workouts, work calls and gaming. The 6mm dynamic driver with a 20 Hz–20,000 Hz range and 16-ohm impedance is a standard, sensible tuning for everyday listening, and the translucent case with a strap holder is a genuinely practical touch for people who lose things in bags. Who should skip it: if you already own Galaxy Buds2 and only need to replace one side, buying a whole new set is overkill. Also skip it if you need a waterproof rating beyond splashes — IPX4 is sweat and light rain, not swimming.
This one is a specialist product, and it is honest about that. The wusheation Single Right Ear is a replacement right earbud designed specifically for the Samsung Galaxy Buds2 (SM-R177). If you lost the right bud, or it stopped charging or stopped producing sound, this gets you back to a working pair without paying for a full new set. That is the entire value proposition, and for the right buyer it is a very good one.
The important detail is compatibility. It is built to fit and charge in your original Galaxy Buds2 charging case, and it keeps the same balanced sound signature and Active Noise Cancelling as the original. It also supports the seamless handoff between Galaxy devices that Buds2 owners rely on, and the compact ergonomic shell is the same shape, so the fit and seal feel like what you had before. It arrives in Olive Green for the right side, matching one of the standard Buds2 finishes.
Who should buy it: Galaxy Buds2 owners with a dead or missing right earbud who still have a working left bud and a working case. Who should skip it: everyone else. If your earbuds are not Galaxy Buds2, this will not serve you — not because it is a bad product, but because it is a part, not a platform. Pairing is handled with an included Simple Sync Guide, and each unit is tested before shipping, so the setup process is meant to be quick rather than a project.
• Best for battery life → JVC Gumy. 26 hours total, 6 per charge, 20 from the case, with a 2-hour charge time on both.
• Best for a lost right earbud → wusheation Single Right Ear. It is literally built for that exact problem on Galaxy Buds2.
• Best for workouts and running → JVC Gumy. IPX4 splashproofing plus four ear tip sizes for a secure seal, and a stem design meant to stay put.
• Best for keeping your existing Galaxy Buds2 setup → wusheation Single Right Ear. It charges in your original case and keeps ANC and Galaxy device switching.
• Best for gaming and video → JVC Gumy. The low-latency mode is there specifically to remove audio delay.
• Best for noise cancelling awareness control → JVC Gumy. ANC plus a dedicated Ambient Sound Mode gives you both isolation and awareness.
• Best value for a full set → JVC Gumy. For a first pair or a full replacement, you get the case, four sets of ear tips, the cable and the manual in one box.
• Best value for a repair → wusheation Single Right Ear. If one bud is the only thing broken, replacing one bud is the smarter spend than replacing the pair.
In my opinion, these are not really competitors — they are two different answers to two different questions. If you are shopping for true wireless earbuds to actually use, I would buy the JVC Gumy. It gives you ANC, Ambient Sound Mode, Bluetooth 5.4, low-latency gaming, IPX4 protection and 26 hours of total battery in one complete package, and the four ear tip sizes mean you can actually dial in the fit. If you own Galaxy Buds2 and only the right side is dead, I would buy the wusheation Single Right Ear — it fixes the exact problem for a fraction of the hassle of starting over. Match the product to your situation and you cannot go wrong.
FAQ
how to pair true wireless earbuds
how to connect true wireless earbuds
Connecting is the same one-time Bluetooth step as pairing — after the first link, most phones reconnect automatically when you open the case. The JVC Gumy's touch controls handle playback and noise mode switching once connected, so you rarely need to touch your phone. For the wusheation bud, connection happens through your Galaxy Buds2 setup, which keeps the seamless switching between Galaxy devices you already had.
how to use true wireless earbuds
On the JVC Gumy, use the touch controls to play, pause and switch between Active Noise Cancelling and Ambient Sound Mode, and pick the ear tip size (S, M, L or XL) that gives you a proper seal. The low-latency mode is worth enabling for gaming and video. On the wusheation Single Right Ear, you use it exactly as you used your original Galaxy Buds2 right bud — same fit, same case, same ANC.
how to bluetooth true wireless earbuds
Bluetooth pairing is done from your phone's settings menu, not from the earbuds themselves. The JVC Gumy runs Bluetooth 5.4 with a 10-meter range, so keep your phone nearby during the initial link. The wusheation Single Right Ear uses Bluetooth through the Galaxy Buds2 system, meaning you pair the set as a whole rather than the replacement bud on its own.
