If you want ear tips with broad stated compatibility and a grippy surface for active use, choose AZLA SednaEarfit Crystal; if you need replacement tips made specifically for JBL Endurance Race TWS earbuds, choose Klowcok Ear Tips Replacement. For Switch listening, I’d start with AZLA’s wider compatibility—but only if your earbuds match its fit and case requirements.
• AZLA SednaEarfit Crystal’s strength: hypoallergenic German LSR silicone, a naturally grippy surface, and compatibility with several wireless-earbud models. Trade-off: its compatibility is not universal, and the short core may not fit every earbud.
• Klowcok’s strength: a clearly specified match for JBL Endurance Race TWS earbuds, with nine pairs across three sizes. Trade-off: it is listed for that JBL model, not as a broadly compatible option.
• AZLA is for: people who need replacement tips for a compatible set of earbuds and value grip, size options, and passive sound isolation.
• Klowcok is for: JBL Endurance Race owners who want a straightforward silicone replacement set with multiple size choices.
• These are replacement tips, not earbuds. Neither set adds Bluetooth, a microphone, a battery, or Switch connectivity. Your earbuds provide those functions; the tips affect fit and the seal at your ear. That distinction matters if you’re searching for the best lightweight wireless earbuds for Switch or the best Bluetooth headset for Switch. These products cannot fill either role on their own.
AZLA’s strongest case is its combination of hypoallergenic German LSR silicone and a naturally grippy surface. The stated design aims to keep compatible earbuds more securely in place during workouts, commutes, and everyday movement. It also aims to improve passive sound isolation through an acoustic seal without changing the earbuds’ original sound signature.
The tips are offered in multiple sizes, and the description notes that their size options were developed after examining more than 1,500 ears over two years. AZLA lists compatibility with Beats Powerbeats Pro and Powerbeats Pro 2, and with Galaxy Buds 2, Galaxy Buds, and Galaxy Buds+. It also describes them as compatible with many popular wireless earbuds, but that does not mean they fit every model. Check the fit and charging-case requirements for your exact earbuds before choosing them.
I’d consider AZLA if grip, a choice of sizes, and compatibility with a listed earbud model matter to you. I’d skip it if you own Galaxy Buds Pro, Galaxy Buds Live, or AirPods Pro: those models are explicitly listed as incompatible. Its 4 mm ultra-short core is intended to fit a wide range of TWS earbuds, but “wide range” is not the same as universal fit.
Klowcok is the more focused option. These silicone tips are specified for JBL Endurance Race TWS earbuds, so the first question is simple: do you own that model? If yes, the listing gives you a direct target for compatibility rather than asking you to infer fit from a broad list of earbud families.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

The package includes nine pairs: three pairs each in small, medium, and large. Klowcok describes the silicone as soft and lightweight, and the tips as washable, durable, easy to replace, and intended to fit securely. The design is also described as providing noise blocking. Those are useful features in a replacement set, but they don’t establish a specific level of isolation or guarantee the same fit for every listener.
I’d choose Klowcok when replacing tips on JBL Endurance Race earbuds is the whole job and having three size options is useful. I’d skip it if you need tips for another earbud model: the stated compatibility is narrow, and the data doesn’t support treating this as a general-purpose replacement set.
• For Beats Powerbeats Pro or Powerbeats Pro 2 → AZLA SednaEarfit Crystal. Those models are specifically included in AZLA’s compatibility information.
• For JBL Endurance Race TWS earbuds → Klowcok. It is the model this set is specified to fit.
• For a naturally grippy tip surface → AZLA. Its LSR silicone is described as having a tacky feel intended to help hold earbuds in place during daily activity.
• For nine pairs in three sizes → Klowcok. The set includes three pairs each of small, medium, and large.
• For listed Galaxy Buds 2, Galaxy Buds, or Galaxy Buds+ compatibility → AZLA. Avoid assuming that this includes Galaxy Buds Pro or Galaxy Buds Live; AZLA excludes both.
• For passive sound isolation while aiming to preserve your earbuds’ sound → AZLA. That is the role described for its acoustic seal.
• For washable replacement tips → Klowcok. Its product information specifically describes the silicone tips as washable.
• For Switch use → choose based on your earbuds, not the console. Neither set provides wireless audio hardware; the relevant choice is which tip set fits the earbuds you already use with your Switch.
The main decision is not which set has more impressive wording. It’s whether your earbud model is among the ones the manufacturer names. If it is not, neither sheet gives enough information to promise a fit. A well-designed tip is still the wrong choice if it won’t attach securely or let the earbuds sit properly in their case.
For people who move around while listening, AZLA’s grippy surface is a practical differentiator. It may be especially appealing if you want tips intended to help your earbuds stay put during a commute or workout. That is a design intention, not a guarantee that every ear will get the same hold. Fit depends on both the tip size and the shape of your ear.
Klowcok takes a simpler route: a model-specific replacement set with three sizes, plus washable silicone tips. That can make the decision uncomplicated for JBL Endurance Race owners. Its limited stated compatibility is the important constraint, though. Don’t buy it for another JBL model—or another brand—just because the tips look similar.
Sound isolation is another point where fit matters more than a general promise. AZLA describes an acoustic seal intended to improve passive isolation while preserving the earbuds’ original sound. Klowcok describes noise blocking. Neither product adds electronic noise cancellation, and neither sheet gives a measured isolation level. A snug, comfortable fit is the sensible goal; the product descriptions alone can’t tell you which size will seal best in your ears.
If your goal is gaming on Switch, keep the accessory’s job in perspective. Ear tips can change how compatible earbuds sit and seal, but they do not turn wired or non-Bluetooth earbuds into a Bluetooth headset. They also don’t specify latency, microphone performance, battery life, or Switch compatibility. Choose tips based on your earbud model, then assess the earbuds themselves for the gaming features you need.
My Verdict
I’d buy AZLA SednaEarfit Crystal if my earbuds were on its compatibility list and I wanted the grippy surface, multiple sizes, and stated focus on passive isolation. For Switch listening, I’d make that choice only after confirming the earbuds themselves work with my setup; the tips don’t provide Bluetooth. If I owned JBL Endurance Race TWS earbuds, I’d choose Klowcok instead because its compatibility is specifically stated for that model.
The supplied compatibility information does not name JBL Endurance Race. AZLA says the tips fit many popular wireless earbuds, but that broad statement is not enough to confirm a match for this specific model.
The stated compatible model is JBL Endurance Race TWS earbuds. The available product information does not confirm compatibility with other earbuds, so I would not assume these tips fit a different model.
AZLA describes a seal intended to improve passive sound isolation without changing the earbuds’ sound signature. Klowcok describes its tips as providing noise blocking. Neither description supplies measured results, so fit and your ear shape remain important.
No. These are replacement ear tips, not audio devices. They do not add Bluetooth, a microphone, or a battery; Switch use depends on the capabilities of the earbuds and your setup.
