How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to protect a pair of Beats Studio Buds you already own and want a case that is genuinely hard to lose track of, choose KOUJAON Case Compatible; if you need the actual wireless earbuds to listen with — long battery life, a low-latency Bluetooth 5.3 connection and a waterproof shell for training — choose Wekily Earbuds. These two products sit in completely different categories, so the honest answer is that most shoppers only need one of them. The real decision is whether you are accessorizing earbuds you already have or buying a new pair outright.
• KOUJAON Case Compatible — biggest strength: a purpose-built silicone shell for Beats Studio Buds (2021) and Beats Studio Buds + (2023), with precise cutouts, shock-absorbing protection and a five-leaf clover keychain that makes the buds easy to spot in a bag.
• KOUJAON Case Compatible — biggest trade-off: it is a case only. It does not produce sound, and it only fits those two Beats models — it is useless with any other brand.
• Wekily Earbuds — biggest strength: a full audio package with 14.2 mm dynamic drivers, Bluetooth 5.3, a 48-hour total playtime figure with the charging case, IPX7 waterproofing and four ENC microphones for calls.
• Wekily Earbuds — biggest trade-off: it is a self-contained system, not an accessory — it will not protect or fit your existing Beats buds, and it relies on its own charging case for the headline battery number.
• Who each pick is for: KOUJAON Case Compatible is for someone who already owns Beats Studio Buds and wants protection plus a way to stop losing them; Wekily Earbuds is for someone who wants a complete, sport-ready pair of wireless earbuds from scratch.
This is a single-purpose product, and it is good at that one purpose. The KOUJAON case is molded silicone with precise cutouts for the Beats Studio Buds (2021) and Beats Studio Buds + (2023). That means the lid lines up, the charging port stays reachable and the buds pop in and out without wrestling. The material is listed as waterproof and shock-absorbing, which is exactly what you want from a case: it soaks up the daily bumps, scrapes and pocket lint that would otherwise land on a glossy charging case. At 0.07 kg, it adds very little bulk, and the Rose Gold finish with a nature-themed pattern gives it a look that plain black plastic does not.
Who should skip it? Anyone who does not own Beats Studio Buds or Beats Studio Buds +. Compatibility is the whole point here, and it is narrow — the sheet lists those two models specifically. If you own a different brand, this case will not fit, no matter how much you like the keychain. And if what you actually need is working earbuds rather than protection for earbuds you already have, this product does not do that job at all.
Wekily Earbuds: Who It's For
The Wekily S50 is a complete wireless earbud system, and the spec sheet reads like a checklist of what people actually complain about with budget buds. Start with the connection: Bluetooth 5.3 with a stated range of up to 15 meters. That is enough to leave your phone on a gym bench or a desk and keep walking. Pairing is automatic after the first connection — open the case and they reconnect, which removes the fiddly part of daily use.
Audio is handled by 14.2 mm dynamic drivers, which is a large driver for an in-ear bud and the reason Wekily can claim powerful bass alongside soft mids. On calls, there are four ENC noise-cancelling microphones, with the brand stating up to 85% vocal enhancement and up to 90% ambient noise reduction. Treat those as manufacturer figures rather than lab results, but the design intent is clear: this is a headset built for people who take calls in noisy places. Note that the noise control listed is passive — there is no active noise cancellation here — so expectations should be about call clarity, not about silencing a plane cabin.
Battery is the headline. Wekily lists 6–8 hours per charge and up to 40 hours from the case, with the description rounding that to 48 hours of total listening. The dual LED display shows the charge level of the buds and the case separately, so you are not guessing. Type-C charging gives a claimed 10 minutes for an hour of playback — a genuinely useful number if you are heading out the door.
For sport, the IPX7 rating means splashes, rain and heavy sweat are not a problem. Each bud weighs 4 grams, the case 30 grams, and there are three ear tip sizes (S/M/L) in the box. The touch controls handle calls, track skipping and voice assistants. Compatibility covers iOS, Android, tablets, laptops and TVs — anything Bluetooth. Who should skip it? Anyone who wants a wired connection, since there is no jack. And anyone who already owns Beats Studio Buds and just needs a case — this is a different purchase entirely.
• Best for protecting earbuds you already own → KOUJAON Case Compatible. It exists solely for Beats Studio Buds (2021) and Beats Studio Buds + (2023).
• Best for actually listening to music → Wekily Earbuds. The KOUJAON product has no drivers and makes no sound.
• Best for battery life → Wekily Earbuds. 6–8 hours per charge and up to 40 hours from the case, with a dual LED display to track it.
• Best for calls in noisy environments → Wekily Earbuds. Four ENC microphones with stated vocal enhancement and ambient noise reduction.
• Best for workouts and rain → Wekily Earbuds. IPX7 waterproofing on the buds themselves versus a waterproof silicone shell for a case.
• Best for not losing your earbuds → KOUJAON Case Compatible. The detachable stainless steel clover keychain clips to a bag, belt or keys.
• Best as a gift for someone who owns Beats → KOUJAON Case Compatible. The Rose Gold finish and keychain make it a presentable, low-risk accessory.
• Best if you are starting from zero → Wekily Earbuds. One purchase covers the buds, the case, the cable and three ear tip sizes.
In my opinion, the right buy depends entirely on what is already in your pocket. If you own Beats Studio Buds and they are rattling around unprotected, I would buy the KOUJAON Case Compatible — the precise fit, shock-absorbing silicone and clover keychain solve two real problems for a fraction of what new earbuds cost, and the compatibility list tells you honestly whether it will work for you. If you do not own Beats buds and you need something to listen with, I would buy the Wekily Earbuds instead, because Bluetooth 5.3, 14.2 mm drivers, IPX7 and a 48-hour total playtime figure cover the essentials for commuting, training and calls. They are not competitors. Pick the one that matches your situation.
FAQ
No. The listing names Beats Studio Buds (2021) and Beats Studio Buds + (2023) only. If you own a different model, this case will not fit properly.
The noise control listed is passive, so there is no ANC engine. What you do get is four ENC microphones tuned to improve your voice on calls and reduce background noise on the other end.
Wekily lists 6–8 hours per charge and up to 40 hours via the charging case, with the description citing 48 hours of total playback. Type-C fast charging is claimed to give an hour of music from a 10-minute top-up.
They serve different jobs. If you already own Beats Studio Buds, buy the KOUJAON case. If you need earbuds to listen with, buy the Wekily set. Check the current price on Amazon before deciding, since only you know your budget.
