If you want lightweight silicone replacement tips in three sizes for several compatible JBL earbuds, choose NANLANFAN Replacement Silicone Ear; if you need a larger set of replacement tips specifically for JBL Endurance Race TWS Earbuds, choose Klowcok Ear Tips Replacement. For airplane use, I’d favor fit and compatibility over assuming either tip will cancel cabin noise: neither sheet specifies active noise cancellation or a noise-reduction rating.
NANLANFAN Replacement Silicone Ear vs Klowcok Ear Tips Replacement at a Glance
• Klowcok’s strength: nine pairs total, with three pairs in each of S, M, and L, plus washable tips. Trade-off: compatibility is specifically listed for JBL Endurance Race TWS earbuds.
• Choose NANLANFAN if you have one of its listed compatible models and want replacement tips for a broader range of JBL Endurance earbuds.
• Choose Klowcok if your earbuds are the JBL Endurance Race and you want three pairs in every listed size.
• These are replacement ear tips, not headphones. Neither package includes earbuds, and neither product is described as a rechargeable over-ear headset.
NANLANFAN Replacement Silicone Ear: Who It's For
NANLANFAN is a straightforward replacement-tip option for owners of JBL Endurance Peak 3, Peak II, Peak, Run 2 Wired, or Race TWS earbuds. Its tips use soft, lightweight silicone and come in three sizes: S, M, and L. That range gives buyers a way to choose a tip size that feels more secure in their own ear, rather than being limited to a single fit. The listing describes six pairs in total.
Fit matters with an ear tip because it sits between the earbud and the ear. NANLANFAN says the tips are designed to stay securely in place and to block unwanted noise. Those are useful aims for commuting or sitting through a flight, where a loose tip can be distracting and a comfortable seal may help reduce outside sound. The sheet does not provide a measured noise-blocking rating, however, so I would treat that as a general design claim, not a promise of cabin-noise cancellation.
The compatibility list is NANLANFAN’s clearest advantage. It includes several Endurance models, not just the Race. That makes it a sensible candidate if you own one of the named earbuds and need a simple replacement set with three size choices. It is also the more flexible pick for households or owners with more than one of those listed models, though the sheet does not say how many tips are needed for each particular earbud.
Who should skip it: Skip NANLANFAN if you need nine pairs, want a stated washable design, or own a model outside its compatibility list.
Klowcok is the more narrowly targeted option. Its compatibility information identifies JBL Endurance Race TWS earbuds, and the package contains nine pairs of silicone tips: three pairs each in S, M, and L. If you own that specific model, the equal distribution gives you several replacements in whichever of the three sizes fits best. The earbuds themselves are not included.
Like NANLANFAN, Klowcok uses soft, lightweight silicone and describes the tips as secure-fitting and effective at blocking noise. It also says they are washable and durable. Washability can be a practical distinction for a small part that sits in the ear, although the product information does not explain a cleaning method or provide a durability period. Buyers should follow sensible care practices rather than infer that the tips can withstand any cleaning routine.
For airplane travel, Klowcok may suit someone who already owns the compatible JBL Endurance Race earbuds and wants multiple replacement pairs on hand. A correctly fitting tip may help with comfort and passive noise blocking, but these are not sleep headphones as a product category, and the data does not describe active noise cancellation, battery life, Bluetooth performance, or an over-ear design. Those features belong to the earbuds or headset, not to these replacement tips.
Who should skip it: Skip Klowcok if your earbuds are not the JBL Endurance Race, or if you need compatibility explicitly listed for Peak or Run 2 models.
• For the broader listed JBL Endurance compatibility → NANLANFAN Replacement Silicone Ear. Its sheet names Peak 3, Peak II, Peak, Run 2 Wired, and Race TWS earbuds.
• For JBL Endurance Race TWS earbuds specifically → either may fit according to the sheets. Klowcok names Race directly; NANLANFAN also includes Race in its compatibility list.
• For six pairs of replacement tips → NANLANFAN Replacement Silicone Ear. Its title specifies six pairs across three sizes.
• For washable tips → Klowcok Ear Tips Replacement. Washability is stated for Klowcok, but not for NANLANFAN.
• For choosing among S, M, and L → both. Each product offers all three sizes; Klowcok specifies three pairs per size.
• For secure fit and noise blocking as stated design aims → both. Neither sheet supplies a quantified noise-reduction result, so don’t treat either as a substitute for active noise cancellation.
• For a rechargeable over ear headphones for airplane search → neither is the right product type. These are silicone ear tips, not headphones; the sheets give no battery or Bluetooth specifications.
Start with the earbud model, not the number of pairs. Replacement tips need to match the earbuds’ shape and fit, and the compatibility lists are not identical. NANLANFAN names several JBL Endurance models, including Peak 3, Peak II, Peak, Run 2 Wired, and Race TWS. Klowcok names JBL Endurance Race TWS. If your model is not explicitly listed, don’t assume compatibility just because both products are silicone tips intended for JBL earbuds.

For a flight, it is important to keep the product category straight. Neither option is a rechargeable over ear headphones for airplane setup, nor does either make a Bluetooth headset. They are replacement silicone tips for compatible earbuds. They may contribute to passive noise blocking when fitted properly, but the specifications do not establish a noise-cancellation level or promise silence in a cabin. If your priority is reducing steady engine noise, these sheets alone are not enough to compare that performance.
The same distinction applies to the phrase best bluetooth headset for airplane. Neither product is a headset, and neither sheet gives battery life, Bluetooth version, microphone details, or onboard controls. Likewise, someone searching for sleep headphones for airplane should know these are only replacement tips. The information provided does not describe a sleep-specific shape or establish that either option is comfortable for sleeping on one’s side.
Finally, consider whether the extra pairs and stated care details matter to you. Klowcok supplies nine pairs and identifies them as washable. NANLANFAN supplies six pairs and lists more compatible earbud models. Those are concrete differences; the sheets do not provide enough information to compare long-term lifespan or to say that one material is softer or more durable than the other.
I would choose NANLANFAN if I owned one of its listed JBL Endurance models, because its compatibility list covers more models while still offering S, M, and L tips. For airplane use, I would treat either set as a replacement-fit accessory, not as a solution for active noise cancellation. If I had JBL Endurance Race earbuds and wanted more spare pairs plus stated washability, I’d choose Klowcok instead.
Both sheets list JBL Endurance Race TWS earbuds as compatible. NANLANFAN also names Peak 3, Peak II, Peak, and Run 2 Wired models, while Klowcok’s listed model is Endurance Race.
Klowcok includes nine pairs, with three pairs each in S, M, and L. NANLANFAN’s title specifies six pairs in those three sizes.
Both products describe noise blocking, but neither provides a measured rating or specifies active noise cancellation. The tips are replacements for compatible earbuds; they are not a standalone way to eliminate cabin noise.
Choose based first on your exact earbud model and fit needs. NANLANFAN covers more of the listed JBL Endurance models; Klowcok offers more pairs and states that its tips are washable. Neither is a headset or a sleep-headphone product.

Side-by-Side: Which Should You Choose?
• For broader listed JBL Endurance compatibility → NANLANFAN Replacement Silicone Ear. Its sheet names Peak 3, Peak II, Peak, Run 2 Wired, and Race TWS earbuds.
• For JBL Endurance Race TWS earbuds specifically → either may fit according to the sheets. Klowcok names Race directly; NANLANFAN includes Race in its compatibility list too.
• For the larger stated package → Klowcok Ear Tips Replacement. It includes nine pairs, divided evenly across S, M, and L.
• For six pairs of replacement tips → NANLANFAN Replacement Silicone Ear. Its title specifies six pairs across three sizes.
• For washable tips → Klowcok Ear Tips Replacement. Washability is stated for Klowcok, but not for NANLANFAN.
• For choosing among S, M, and L → both. Each product offers all three sizes; Klowcok specifies three pairs per size.

If your model is not explicitly listed, don’t assume compatibility just because both products are silicone tips intended for JBL earbuds.
Next, consider how you use your earbuds. Three sizes give you options, but the sheets don’t identify which size will fit any individual. If you wear earbuds for long stretches, including during a flight, comfort and a secure fit are practical priorities. A tip that feels uncomfortable or loosens easily is unlikely to be a good travel companion, regardless of how many spare pairs are included.
