If you want more specific sound-shaping features for children’s existing earbuds, choose PENON ePro EP01; if you need replacement tips for compatible JBL earbuds, choose NANLANFAN Replacement Silicone Ear. PENON offers a horn-shaped design and a broad stated nozzle fit, while NANLANFAN is the more focused pick for several JBL models.
PENON ePro EP01 vs NANLANFAN Replacement Silicone Ear at a Glance
• PENON ePro EP01’s biggest strength: a horn-shaped silicone design intended to shape sound and reduce sound transmission loss. Trade-off: compatibility is based on nozzle diameter, so you need to check that your earbuds’ nozzles fall within the stated range.
• NANLANFAN’s biggest strength: replacement tips made for several specified JBL earbud models, with three tip sizes. Trade-off: its stated compatibility is model-specific rather than a general nozzle-diameter range.
• PENON includes: S, M, and L tips, with a 4.7 mm inner diameter for earphone nozzles measuring 4.9–7 mm.
• NANLANFAN includes: S, M, and L silicone tips and names compatible JBL Endurance Peak and related models.
• Choose PENON if your earbuds meet its nozzle requirements and you want to consider a sound-focused tip design. Choose NANLANFAN if you own one of its listed JBL models and want replacement tips for it.
PENON ePro EP01 is a set of replacement eartips for wired in-ear monitors, wireless earbuds, and other compatible in-ear earphones. Its distinguishing feature is a horn-shaped opening, which PENON says is designed to help shape sound as it travels through the tip. The silicone is described as graphene-doped, and the set comes in S, M, and L.
The key fit check is the nozzle: these tips have a 4.7 mm inner diameter and are stated to fit earphone tubes from 4.9 mm to 7 mm in diameter. If your child already has earbuds within that range, PENON is worth considering when you want a replacement tip with sound-shaping features. PENON also describes the tips as washable, flexible, and intended for a secure fit during movement.
I would skip this set if you need tips explicitly matched to a particular JBL model and do not know whether its nozzle fits the stated range. The horn shape and sound-related claims are design intentions, not a reason to assume every earbud will sound the same with these tips. For children, fit comes first: the included sizes provide options, but the product information does not establish a child-specific fit or make these a substitute for headband headphones.

NANLANFAN Replacement Silicone Ear: Who It's For
NANLANFAN’s replacement silicone tips are aimed at owners of the JBL Endurance Peak 3, Peak II, Peak, Run 2, and Race TWS earbuds. That model-specific compatibility is its clearest advantage. If a child’s earbuds are one of those models, this is the more direct match on paper than a set selected by nozzle diameter alone.
This is not the pick for someone seeking a broadly specified fit across unrelated earbuds. Its compatibility information names particular JBL models, rather than giving a nozzle-diameter range. Before choosing it for a child, confirm the earbud model and select an appropriate tip size. Like PENON, it is a replacement-tip set, not a complete listening device or a pair of headband headphones.
• Best match for several named JBL earbuds → NANLANFAN Replacement Silicone Ear. Its compatibility information names the Endurance Peak 3, Peak II, Peak, Run 2, and Race TWS earbuds.
• Best for checking fit by nozzle diameter → PENON ePro EP01. It states a 4.7 mm inner diameter and a compatible nozzle range of 4.9–7 mm.
• Best if sound shaping matters to you → PENON ePro EP01. Its horn-shaped design is intended to shape sound and support bass, vocal clarity, and high-frequency detail.
• Best if you want simple model-specific replacement tips → NANLANFAN. Its stated purpose is to replace tips on the named JBL models, without a separate sound-shaping design described in the product details.
• Best for choosing among S, M, and L → either. Both sets include those three sizes; neither product information provides a child-specific sizing guide.
• Best for movement-related use → PENON, if the fit is compatible. PENON describes the tips as secure and suitable for workouts and active use. NANLANFAN also describes a secure fit, but gives less detail about use during movement.
• Best for a child whose earbuds are not a listed JBL model → PENON may be easier to assess. Its stated nozzle range gives you a concrete measurement to compare, though compatibility still depends on a suitable fit.
• Best option if you are shopping for headband headphones for children → neither. These products are eartips for existing earbuds, not headband-style headphones.
A parent weighing the best wireless earbuds for children against headband headphones should first settle the kind of device they need. These two products only address replacement tips for earbuds. They do not include earbuds, a headband, or other headphone components.
My Verdict
In my opinion, I would choose PENON ePro EP01 for a child’s existing earbuds if the nozzle measures within its stated 4.9–7 mm range. Its sound-focused design and washable, flexible silicone give it more specific features to weigh.
No. Both products are replacement silicone eartips for compatible earbuds or in-ear earphones. They do not include an earbud or a headband.
NANLANFAN lists compatibility with JBL Endurance Peak 3, Peak II, Peak, Run 2, and Race TWS earbuds. Check the exact model before choosing, since PENON gives a nozzle-size range rather than naming those JBL models.
PENON states that the tips fit earphone nozzles from 4.9 mm to 7 mm, and describes them for a range of in-ear monitors and wireless earbuds. Measure or confirm the nozzle size before choosing; the stated range does not guarantee a comfortable fit for every earbud or wearer.
PENON describes a horn-shaped design intended to shape sound and support bass, vocals, and high-frequency clarity. NANLANFAN says its tips block unwanted noise, but provides no numerical isolation figure. Those descriptions do not establish how either set will perform with every earbud.
