If you want replacement silicone ear tips that keep JBL Endurance TWS earbuds locked in and sealed, choose NANLANFAN Replacement Silicone Ear; if you need a complete pair of true wireless earbuds with a battery display and touch controls, choose Generic M25. These two look like they belong in the same search, but they solve completely different problems — one is a consumable accessory, the other is the audio device itself.
• NANLANFAN Replacement Silicone Ear — biggest strength: a 6-pair silicone tip set (S/M/L) that fits JBL Endurance Peak 3, Peak II, Peak, Run 2 Wired and Race TWS earbuds, restoring a secure, noise-blocking seal.
• NANLANFAN Replacement Silicone Ear — biggest trade-off: it is an accessory only. No drivers, no battery, no Bluetooth. If you don't own a compatible JBL model, it does nothing for you.
• Generic M25 — biggest strength: a full TWS package — Bluetooth 5.3, touch controls, an LED status display, a 2000 mAh case and a 13.4 mm dynamic driver.
• Generic M25 — biggest trade-off: generic build with a short 1-month warranty and no brand-name support behind it.
• Buy NANLANFAN Replacement Silicone Ear if you already own JBL Endurance TWS earbuds and the tips are worn, lost or no longer sealing properly.
• Buy Generic M25 if you need working wireless earbuds from scratch and want touch control plus a battery readout on the case.
This is a maintenance product, and it's honest about that. The NANLANFAN set is six pairs of soft silicone ear tips in small, medium and large, made to fit a specific family of JBL Endurance TWS models: the Peak 3, Peak II, Peak, Run 2 Wired and Race. The silicone is described as high-quality and ultra-light, and the whole point of replacing tips is the fit — a proper seal is what keeps an earbud from working its way loose mid-run and what actually blocks outside noise.
In my opinion, this is the right buy for one specific person: someone who already owns one of those JBL models and whose original tips have stretched, torn, gone missing or simply stopped holding a seal. If your earbuds keep slipping during workouts, or the bass has gone thin because air is leaking around the tip, fresh tips are the cheap fix. Getting three sizes in one pack also means you can experiment — many people wear a medium in one ear and a large in the other, and a multi-size set lets you sort that out without guessing.
Generic M25: Who It's For
The M25 is a complete true wireless earbud kit. It runs Bluetooth 5.3 with a stated range of about 33 feet, uses touch controls for playback, calls and volume, and puts an LED screen on the case so you can see battery status and connection info at a glance. The case itself carries a 2000 mAh battery rated for roughly 20 hours of average use, with a 1.5-hour charge time. Inside each bud is a 13.4 mm dynamic driver with a 32-ohm impedance, a 20 Hz frequency response and 98 dB sensitivity — numbers that suggest a bass-forward, easy-to-drive sound.
It's aimed at the everyday wireless listener: commutes, workouts, calls on the go. The waterproof design is described as protected against splashes and sweat, which lines up with the workout angle, and the noise control is passive — meaning the seal and tip design do the isolating rather than active cancellation. Latency is listed at 40 ms, which is fine for music and casual video.
Who should skip it? Buyers who want a known brand name, a long warranty or premium build materials. The warranty is listed at one month, the housing is plastic and the brand is simply "Generic" — so you're buying on specs and features, not on reputation. If you're the type who wants support to still be there in a year, that's the real trade-off here. Also note the item weight of 1.8 ounces for the buds and a 2.5-ounce case — light enough to pocket, but the case is a full 3.5 x 2.5 x 1.5 inches, so it's on the bulkier side for a coin-pocket carry.
Side-by-Side: Which Should You Choose?
• You already own JBL Endurance Peak/Run/Race TWS earbuds → NANLANFAN Replacement Silicone Ear. It's built for exactly those models.
• You need earbuds, not parts → Generic M25. It's the only one of the two that actually plays audio.
• Best for workouts with sweat → Generic M25. Its waterproof design is meant for sweat and splashes; the NANLANFAN set is just silicone tips.
• Best for battery visibility → Generic M25. The LED display and 20-hour case battery give you a live status readout.
• Best for passive noise blocking on JBL buds → NANLANFAN Replacement Silicone Ear. Fresh, properly sized tips are what restore that seal and cut ambient noise.
• Best for control convenience → Generic M25. Touch control for playback, calls and volume beats reaching for your phone.
• Best low-risk fix → NANLANFAN Replacement Silicone Ear. Six pairs means spares for later; there are no electronics to fail.
In my opinion, most people searching this comparison should buy the NANLANFAN Replacement Silicone Ear — but only if they already own a compatible JBL Endurance model. In that case, it's the practical, low-risk move: a secure fit, better noise blocking and spare pairs in three sizes, with nothing to charge or update. I'd choose the Generic M25 instead if the real problem is that you have no working earbuds at all. It's a complete TWS package with Bluetooth 5.3, touch controls, an LED battery display and a 20-hour case — just go in knowing the warranty is short and the brand is generic. Match the product to your actual problem and either one does its job well. Check the current price on Amazon before you commit.
how to pair tws earbuds
Take both earbuds out of the case and they should enter pairing mode and link to each other automatically, since TWS (True Wireless Stereo) technology handles that handshake. Then open your phone's Bluetooth settings, find the earbud name in the list and select it. If nothing appears, put them back in the case and start again.
how to connect tws earbuds
Turn on Bluetooth on your device first, then remove the earbuds from the case so they power up and become discoverable. Select the earbud entry on your phone and wait for the confirmation. Once connected, audio routes automatically — the M25's stated Bluetooth range is around 33 feet, so keep your phone nearby.
how to reset tws earbuds
Most TWS models reset by clearing the paired-device memory: delete the earbud entry from your phone's Bluetooth list, then place both buds in the case and take them out again to force a fresh pairing cycle. If they still won't link, charge the case fully — the M25 case charges in about 1.5 hours — and repeat. Exact button or touch sequences vary by model, so check your own manual for the specific reset gesture.
how to tws earbuds
TWS stands for True Wireless Stereo: two independent earbuds that connect to each other and to your device with no cable between them. To use them, charge the case, take the buds out, pair once over Bluetooth, then just reinsert them to charge and remove them to reconnect. The M25 adds touch controls for playback, calls and volume, plus an LED display on the case so you can check battery status at a glance.
