If you want a silicone replacement tip built specifically for the JBL Endurance Race with six pairs across three sizes, choose ALXCD Ear Tips Compatible; if you need slow-rebound memory foam that stays on while you charge your Soundcore buds, choose BLLQ Memory Foam Ear.
• ALXCD Ear Tips Compatible — biggest strength: six pairs of soft silicone tips in S/M/L, a sound-isolating design that cuts ambient noise, and a fiber cleaning cloth in the box.
• ALXCD Ear Tips Compatible — biggest trade-off: it is locked to one earbud family (JBL Endurance Race), so it is useless if you own Soundcore or another brand.
• BLLQ Memory Foam Ear — biggest strength: slow-rebound memory foam in S/M/L that is designed to stay mounted inside the charging case, so you never have to pull tips off to charge.
• BLLQ Memory Foam Ear — biggest trade-off: it only fits Soundcore models, and foam is a wear item that tends to compress and lose its rebound over time.
• Who ALXCD is for: JBL Endurance Race owners who want a big spare-tip stash, a secure silicone seal and a quick cleaning cloth.
• Who BLLQ is for: Soundcore Life P3 / P3i / Liberty 3 Pro / Space A40 owners chasing a deeper bass seal and all-day comfort.
ALXCD Ear Tips Compatible is a single-purpose accessory, and that is the point. It is made for one earbud: the JBL Endurance Race. The tip is soft silicone in black, and the design is described as sound isolating — it reduces the ambient noise that leaks in around a loose fit. Anyone who has ever run with a half-sealed sport bud knows the problem: wind, traffic and gym noise push in, and you crank the volume to compensate. A tip that seals properly is the cheap fix for that, and that is exactly what this kit is aimed at.
The bundle math is the real story here. You get six pairs of silicone tips spread across small, medium and large, plus one fiber cleaning cloth with the ALXCD logo. Six pairs across three sizes means you can find the seal that actually works for your ear, then keep spares. Silicone also holds up better to sweat, rain and repeated wiping than foam does, which matters when the earbuds are made for sport in the first place. The cloth is a small thing, but it is a genuinely useful one — earwax and skin oil are what kill a silicone seal over time, and wiping the tip down keeps it gripping.
Who should skip it? Anyone who does not own JBL Endurance Race earbuds. The compatibility list is that narrow, and there is no adapter or universal fit claim here. If you own Soundcore buds, this is the wrong product entirely — you want the other option on this page. Silicone is also not the tip material for people who want that soft, slow-squish feeling in the ear canal; that is a foam characteristic, not a silicone one.
BLLQ Memory Foam Ear is the foam alternative, and it is built around a specific annoyance: tips that have to come off before the buds go back in the case. BLLQ states these fit perfectly into the charging case, so you leave them on and just drop the earbuds in. If you have ever lost a tip on the floor at 11pm because you had to pry it off to charge, you understand why that is a feature and not a footnote.
The material does the rest. Slow-rebound memory foam is designed to expand into the shape of your ear canal rather than sit against it the way silicone does. BLLQ frames the payoff in two ways: better noise blocking and enhanced bass. That is consistent with how foam works physically — a fuller, more complete seal keeps outside sound out and keeps low frequencies from leaking away. Foam is also the friendlier choice for long sessions, and BLLQ leans into that, calling out all-day comfort and reduced ear pain, with use cases that run from working at home to workouts to video calls.
The catch is fit and longevity. This kit is S/M/L with one pair per size, three pairs total — half the tip count of the ALXCD set, and in white rather than black. The compatibility list covers Soundcore Liberty 3 Pro, Liberty 4, Life P2, Life P3 and Space A40. That is a wider net than ALXCD casts, but it is still a Soundcore-only net. Buy this for a different brand and it will not help you. And because foam compresses with use and picks up skin oils, expect to treat these as a consumable rather than a permanent upgrade. I would keep the spares somewhere I can actually find them.
Side-by-Side: Which Should You Choose?
• Best for JBL Endurance Race owners → ALXCD Ear Tips Compatible. Compatibility is explicit: the JBL Endurance Race.
• Best for noise isolation through seal → BLLQ Memory Foam Ear. Slow-rebound foam expands to fill the canal, which is the more complete seal of the two designs.
• Best for sweat, rain and repeated cleaning → ALXCD Ear Tips Compatible. Silicone shrugs off moisture and wipes down without deforming.
• Best for bass emphasis → BLLQ Memory Foam Ear. BLLQ explicitly ties the foam seal to enhanced bass; a tighter seal is what keeps low end from leaking out.
• Best for charging-case convenience → BLLQ Memory Foam Ear. It is designed to stay on the earbuds inside the case.
• Best for spare-tip quantity → ALXCD Ear Tips Compatible. Six pairs across S/M/L versus three.
• Best for a tip that lasts → ALXCD Ear Tips Compatible. Silicone does not compress and lose rebound the way foam does.
If I owned JBL Endurance Race earbuds, I would buy the ALXCD kit. Six pairs across three sizes means I stop guessing about fit and just keep the size that seals, and silicone is the right material for a sport bud that gets sweaty and wiped down. If I owned Soundcore Life P3, Liberty 3 Pro or Space A40 instead, I would buy BLLQ Memory Foam Ear without hesitating — the charge-case fit and the foam seal are the two things that actually change how the earbuds feel day to day. In my opinion the deciding factor is not which tip is better in the abstract. It is which one is built for the earbuds already in your pocket.
No. ALXCD lists compatibility with JBL Endurance Race only, so they are not a fit for Soundcore models. If you own Soundcore buds, BLLQ Memory Foam Ear is the matching option on this page.
Do BLLQ memory foam tips fit in the charging case?
Yes — BLLQ states the tips fit into the charge case, so you do not need to remove them before charging. That is one of the main practical differences versus pulling silicone tips off every night.
Both use a sealing design, but they do it differently. ALXCD relies on a sound-isolating silicone shape. BLLQ relies on slow-rebound memory foam that expands to fill the ear canal, which BLLQ links to stronger noise blocking and more bass.
ALXCD includes six pairs of silicone tips across S/M/L plus a fiber cleaning cloth. BLLQ includes three pairs of foam tips — one pair each in small, medium and large.
Silicone generally outlasts foam because it does not compress or lose rebound. Foam tips are better treated as a wear item you replace periodically, so the ALXCD set gives you more spares to work through.
