How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to rescue a pair of Bose in-ear headphones you already own, choose WKYMY Earbud Replacement Tips; if you need a complete wireless listening solution that keeps your ears open to traffic, choose GGSTOPWATER Open Ear Headphones. These two products are not really rivals — one is a tiny silicone accessory, the other is a full Bluetooth headset — so the real question is whether you are fixing gear you already have or buying gear you do not have yet. Below I break down exactly who each one is for, using only what the spec sheets actually say.
• WKYMY's biggest strength: it is a direct-fit silicone replacement for Bose QuietComfort and Bose Sport earbuds, with three pairs of small tips plus a case and cleaning cloth, so a damaged or missing tip no longer means retiring the whole headphone.
• WKYMY's biggest trade-off: it does nothing on its own — no drivers, no battery, no Bluetooth. If your Bose headphones are dead, this box cannot help you.
• GGSTOPWATER's biggest strength: it is a self-contained open-ear Bluetooth 5.4 headset with a 16mm dynamic driver, IPX5 water resistance, ear hooks and a charging case.
• GGSTOPWATER's biggest trade-off: open-ear design means you are trading isolation for awareness, and it will not give you the sealed, noise-blocking feel of an in-ear fit.
• Pick WKYMY if you already own compatible Bose QuietComfort or Bose Sport headphones and just need fresh tips.
• Pick GGSTOPWATER if you are starting from zero and want open-ear headphones for running, cycling, driving or long work sessions.
The WKYMY box is a maintenance product, and it is honest about that. What you get is three pairs of small silicone earbud tips with wings, a storage box, and a cleaning cloth. The tips are specified as compatible with Bose QuietComfort and Bose Sport headphones, and they are made from soft, elastic silicone that the spec sheet describes as water-washable, flexible, anti-static, removable and replaceable. The enclosure material is silicone and the earpiece shape is a rounded tip, with a wing that helps the tip seat and stay put in the ear.
That wing matters more than it sounds. Winged tips are what keep an in-ear bud anchored during movement, and when the original wing tears or stretches, the bud starts slipping and the seal goes with it. The WKYMY set is aimed squarely at that failure point. If your tips are cracked, scratched, discolored, or simply gone — one lost tip in a gym bag is enough — this is a cheap way to restore an otherwise perfectly good pair of Bose headphones instead of replacing the headphones themselves.
Who should buy it: anyone with compatible Bose QuietComfort or Bose Sport in-ear headphones whose tips have worn out. Who should skip it: anyone without those specific Bose models, anyone hoping for a universal fit across every brand of earbud, and anyone whose headphones have an electrical fault rather than a tip problem. The spec sheet lists the fit as Bose-specific, so treat that as a hard requirement rather than a suggestion. One practical note the listing itself raises: these are small parts, so keep them away from children.
The GGSTOPWATER JM13 is a completely different animal — a finished, self-contained wireless headset. It uses Bluetooth 5.4, which the spec sheet credits with reduced signal interference and attenuation for a faster, more stable connection, and it supports multi-point linking so you can move between devices. Compatibility is listed as iOS, Android and Windows, which covers phones, tablets, computers and TVs. Controls are handled remotely, with media control and call control, and there is a microphone on board for calls.
The design is the headline. These are open-ear, air-conduction headphones with a hanging ear-hook shape, so nothing plugs your ear canal. The pitch is straightforward: a ventilated, breathable fit that does not press on the ear, which reduces the prolonged-pressure discomfort that sealed in-ears can cause. The flip side is spatial awareness — because your ears stay open, you can hear approaching vehicles and people around you. That is the whole reason this category exists, and it is why the spec sheet points at outdoor sports, office work and driving.
On the audio side, GGSTOPWATER lists a 16mm dynamic driver delivering 360° Hi-Fi stereo, with a frequency range of 20 Hz to 20,000 Hz and 32 ohm impedance. Active noise cancellation is listed under noise control, though with an open-ear fit the practical effect is ambient awareness rather than a sealed bubble of silence — do not expect in-ear-style isolation. The build is silicone with flexible, soft ear hooks for a secure hold, and it carries an IPX5 rating with a nano waterproof coating meant to shrug off sweat and rain. Rounding it out: a charging compartment, a Type-C cable, a manual, and a silicone lanyard in the same color so you can hang the case off a backpack. The color listed is khaki, and there is a 6-month warranty.
Who should buy it: runners, cyclists, gym-goers, drivers and office workers who want audio without blocking the world out, and anyone who finds in-ear buds uncomfortable after an hour. Who should skip it: anyone who wants deep passive isolation on a plane or a noisy train, and anyone who prefers a traditional sealed fit.
• Best for repairing headphones you already own → WKYMY Earbud Replacement Tips. It exists purely to extend the life of compatible Bose QuietComfort and Sport models.
• Best for a complete wireless setup → GGSTOPWATER Open Ear Headphones. Bluetooth 5.4, a charging case and a built-in mic mean it works out of the box with no other purchase.
• Best for outdoor safety → GGSTOPWATER. The open-ear design keeps you aware of traffic and surroundings; the WKYMY tips do nothing for awareness.
• Best for sweat and rain → GGSTOPWATER. IPX5 with a nano waterproof coating is a real rating. The WKYMY tips are water-washable silicone, which is about hygiene, not weather.
• Best for long-wear comfort if you hate things in your ears → GGSTOPWATER. The open, ventilated fit avoids canal pressure entirely.
• Best for keeping an existing in-ear seal intact → WKYMY. Winged silicone tips are what hold a Bose bud in place; fresh ones restore that grip.
• Best for multi-device switching → GGSTOPWATER. Multi-point linking across iOS, Android and Windows.
• Best if you want the smallest possible spend to solve a small problem → WKYMY. It is an accessory, so check the current price on Amazon and compare it against the cost of replacing your headphones.
My Verdict
No. The spec sheet lists compatibility specifically with Bose QuietComfort and Bose Sport headphones. If your earbuds are a different brand or model, do not assume these will fit.
No, and that is intentional. The open-ear, air-conduction design leaves your ear canal unblocked so you can hear traffic and people around you. Active noise cancellation is listed, but the fit itself is built for awareness, not isolation.
The spec sheet lists an IPX5 rating with a nano waterproof coating for daily sweat and rain, plus flexible silicone ear hooks for a secure hold. That combination is aimed directly at fitness and running use.
It depends on what you already own. If your Bose headphones work fine and only the tips are damaged, buy the WKYMY tips. If you have no working headphones at all, buy the GGSTOPWATER Open Ear Headphones — and check the current price on Amazon before deciding, since the two sit in very different budget brackets.
