How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an all-in-one open-ear earbud package with a 64-hour charging case and Bluetooth 5.4, choose GGSTOPWATER Open Ear Headphones; if you need a rugged IPX5 hard-shell protective case for the Shokz OpenFit 2+ charging case you already own, choose PROfezzion Shokz OpenFit 2+. These two products are not really rivals in the usual sense — one is a pair of earbuds, the other is armor for a pair of earbuds — so the honest way to compare them is to figure out which job you actually need done.
• GGSTOPWATER Open Ear Headphones — biggest strength: It's a complete open-ear audio setup: Bluetooth 5.4 earbuds with flexible ear hooks, an IPX5 sweat-resistant rating, touch controls, and a charging case that pushes total playtime to 64 hours.
• GGSTOPWATER Open Ear Headphones — biggest trade-off: It's a single-piece electronics product with a 1-month warranty, and its noise control is listed as Active Noise Cancellation in a form factor (open-ear) that by design doesn't seal your ear canal, so don't expect the isolation of in-ear buds.
• PROfezzion Shokz OpenFit 2+ — biggest strength: A heavy-duty hard-shell case with a secure locking latch, full-coverage IPX5 splash protection, and a non-slip silicone pad that holds the charging case in place without adhesive.
• PROfezzion Shokz OpenFit 2+ — biggest trade-off: It is not a headphone at all. It only fits the Shokz OpenFit 2+ (2025) and is explicitly incompatible with the OpenFit Air (2024) and OpenFit 1 (2023), so it's useless to you unless you already own that exact model.
• Who each pick is for: Choose GGSTOPWATER if you need the earbuds themselves for running, workouts or driving; choose PROfezzion if you already own a Shokz OpenFit 2+ and want to protect its charging case from drops and spills.
The GGSTOPWATER Open Ear Headphones (model XG99) are built around a very specific brief: stay on your head while you move, and stay out of your ear canal while you do it. The open-ear design with flexible, soft ear hooks is meant to sit securely through long workouts, jogs and runs, and the IPX5 rating means sweat and water splashes aren't a problem. If you've ever had a bud slip out mid-sprint or felt sealed-in discomfort on a long ride, that's the problem this shape is solving.
Who should buy it: runners, gym-goers and cyclists who want ambient awareness of traffic and surroundings, drivers who want audio without blocking their ears, and anyone who wants a long-lasting case and doesn't want to fiddle with pairing every time. The included silicone lanyard and compact round case make it easy to clip to a backpack. Who should skip it: if you want deep noise isolation for flights or a noisy open-plan office, an open-ear design is the wrong tool — and note that the listed warranty is only 1 month, so factor that into how you think about long-term ownership.
PROfezzion Shokz OpenFit 2+: Who It's For
Let me be blunt about what this is, because it's the single most important thing to understand: the PROfezzion Shokz OpenFit 2+ is a case cover, not a headphone. It's a heavy-duty hard shell made from ABS, polycarbonate, plastic, metal and silicone, measuring roughly 3.01 x 2.81 x 1.33 inches and weighing about 0.08 kg. It slides over the charging case of the Shokz OpenFit 2+ (2025) open-ear headphones and stays there.
Its job is protection, and it's designed around the failure modes people actually complain about. The secure locking latch holds the charging case shut so the earphone can't pop out during a daily drop. The full-coverage shell guards against splashes and spills with an IPX5 water-resistance rating, and it's also listed as dust resistant, shockproof and spill resistant. Inside the bottom, a non-slip silicone pad grips the charging case firmly so it doesn't rattle around — notably, without the adhesive tape some competing covers rely on. It even comes with a handle, which makes it easier to clip on or grab out of a bag.
Side-by-Side: Which Should You Choose?
• Best for actually listening to music → GGSTOPWATER Open Ear Headphones. It's the only one of the two that produces sound.
• Best for long battery life → GGSTOPWATER Open Ear Headphones. 8 hours per bud plus a case rated for 64 hours total.
• Best for sweat and splash resistance on the earbuds themselves → GGSTOPWATER Open Ear Headphones. IPX5 on the earbuds, aimed at fitness, jogging and running.
• Best for protecting a Shokz OpenFit 2+ charging case → PROfezzion Shokz OpenFit 2+. Locking latch, hard shell, full coverage, IPX5.
• Best for drop-prone, bag-thrown daily carry → PROfezzion Shokz OpenFit 2+. Shockproof construction plus a non-slip silicone pad that needs no adhesive.
• Best for drivers and cyclists who want to hear traffic → GGSTOPWATER Open Ear Headphones. Open-ear placement keeps your ears unsealed.
• Best for warranty peace of mind → PROfezzion Shokz OpenFit 2+. Its listed warranty is 1 year versus 1 month on the GGSTOPWATER.
• Best if you own Shokz OpenFit 2+ and nothing else → PROfezzion Shokz OpenFit 2+. It's purpose-built for that one model and won't fit the Air or the original OpenFit.
In my opinion, this isn't a close call once you know your situation. If you need headphones — for running, workouts, driving, or just open-ear listening with a case that lasts days — I'd buy the GGSTOPWATER Open Ear Headphones, because it's the only product here that actually does the job of playing audio, and the 64-hour combined playtime plus Bluetooth 5.4 covers the everyday basics well. I'd only choose the PROfezzion Shokz OpenFit 2+ if you already own Shokz OpenFit 2+ headphones and your real pain point is a cracked or popped-open charging case, in which case its locking latch and hard shell are exactly the fix. Buy the one that matches the problem you actually have — and check the current price on Amazon before deciding, since these two live in completely different budget categories.
are headphones waterproof
Not in the strict sense — most "waterproof" earbuds, including the GGSTOPWATER Open Ear Headphones, carry an IPX5 rating, which means they resist water splashes and sweat rather than surviving full submersion. The PROfezzion case cover is also rated IPX5, so it handles splashes and spills but isn't meant to be dunked. Treat IPX5 as workout-and-rain protection, not swimming protection.
are headphones water resistant
Yes — IPX5 is a water-resistance rating, and both products here claim it. On the GGSTOPWATER Open Ear Headphones it applies to the earbuds for sweat and splashes during fitness, jogging and running; on the PROfezzion Shokz OpenFit 2+ it applies to the hard-shell case protecting your charging case from spills. Water-resistant means it tolerates exposure, not that you should submerge it.
Only if those earbuds are specifically the Shokz OpenFit 2+ (2025). It's not compatible with the OpenFit Air (2024) or OpenFit 1 (2023), and it does nothing for the GGSTOPWATER earbuds, which come with their own charging case. If you own a different model, this cover won't fit.
For everyday listening, the GGSTOPWATER Open Ear Headphones is the more complete package: Bluetooth 5.4, touch controls, up to 8 hours per charge and 64 hours total with the case. The PROfezzion is a single-purpose accessory — it only adds protection. Decide based on whether you need audio gear or protection for audio gear you already own.
