If you want a rugged, protective shell that shields your JBL charging case from drops, water, and daily wear while keeping it organized in your bag, choose RLSOCO Carrying Case; if you need a comfortable, secure fit with better bass isolation for your JBL earbuds during workouts or long listening sessions, choose Sqrmekoko 3. These two products serve completely different roles in the ecosystem of your audio gear, and picking the right one depends entirely on whether your priority is physical protection or acoustic comfort.
• RLSOCO Carrying Case: Its biggest strength is heavy-duty protection using high-density EVA and fiber materials against shock, dust, and water; its trade-off is that it only works as an external shell for specific JBL models and does not improve sound quality. This pick is for anyone who needs to keep their charging case safe inside a purse or backpack.
• Sqrmekoko 3: Its biggest strength is the soft, skin-friendly silicone material that ensures a snug seal for enhanced bass and noise isolation without irritation; its trade-off is that it offers zero protection for the device itself and is strictly an internal component replacement. This pick is for users who find their current eartips uncomfortable or loose during movement.
The RLSOCO Carrying Case is designed as a fortress for your audio accessories. If you are someone who tosses your JBL Vibe Beam, Tune 230NC, or similar models into a crowded gym bag, a messy desk drawer, or a handbag alongside keys and coins, this case is built specifically for that chaotic reality. The product information confirms it is constructed from high-density Ethylene Vinyl Acetate (EVA) and top-quality fiber materials. This combination creates a rigid barrier that prevents deformation, ensuring your charging case remains intact even after being knocked over or stepped on.
What makes this stand out is the focus on environmental safety and durability. Unlike cheaper alternatives that might smell like harsh chemicals or degrade quickly, RLSOCO uses materials certified by RoHS and SGS standards. You get a hard enclosure that is both water-resistant and scratch-resistant, meaning spills on the sidewalk or accidental scuffs won't ruin the look or function of your electronics. The compact design allows it to slip easily into pockets or bags, making it an essential companion for daily activities where your earbuds are constantly on the move.
However, you must understand what this product is not. It is a storage solution, not a performance enhancer. It contains no electronics, no drivers, and no microphone technology. It is sold as a case only, meaning you already need your own compatible JBL earbuds and charging unit to use it. If you are looking for something to make your music sound deeper or to help you hear calls more clearly, this case will not deliver those results. It is purely a shield. It fits perfectly for commuters, travelers, and active individuals who prioritize keeping their expensive hardware from getting damaged over any other feature.

In contrast, the Sqrmekoko 3 addresses the most common complaint among JBL TUNE120, T125, and T120 TWS users: the fit. Over time, original eartips can lose their elasticity, become dirty, or simply never felt quite right for your unique ear shape. This product replaces those worn-out components with fresh, high-grade silicone gels. The primary benefit here is immediate physical comfort. The material is described as soft, flexible, and gentle on the skin, which is critical for anyone who wears headphones for extended periods, such as during long flights, study sessions, or intense workout routines.
Beyond just comfort, the design of these eartips plays a crucial role in how your music actually sounds. Because they are made to create a tight seal within the ear canal, they block outside noise more effectively than loose-fitting tips. This sealing action naturally enhances the bass response and overall immersion of your audio experience. Whether you are listening to podcasts or bass-heavy tracks, a proper seal ensures you aren't fighting against ambient noise. The package includes three pairs of replacement tips, giving you the flexibility to try different sizes or keep spares handy if you misplace one.
This product is ideal for people who feel their earbuds falling out or who experience ear fatigue after an hour of use. It is also the perfect fix for anyone who has lost their original tips or found them cracked and unusable. Installation is straightforward with no tools required, offering a hassle-free upgrade to your existing JBL earbuds. However, it is important to note that this is strictly an accessory for the earbuds themselves. It does not protect the charging case, nor does it offer any waterproofing for the device. If your main worry is dropping your earbuds on concrete, these eartips won't save the electronics from impact damage. They are all about the connection between the driver and your ear.
• Best for physical protection → RLSOCO Carrying Case: The high-density EVA shell provides superior defense against drops, shocks, and scratches that soft silicone cannot offer.
• Best for acoustic isolation and bass → Sqrmekoko 3: The tight-sealing silicone design blocks external noise and improves low-end frequencies significantly compared to standard tips.
• Best for comfort during long sessions → Sqrmekoko 3: Soft, skin-friendly materials reduce irritation, whereas a hard plastic case offers no direct contact with your ears.
• Best for travel organization → RLSOCO Carrying Case: Its compact, sturdy form keeps your charging case and cables organized and safe in a pocket or bag.
• Best value for longevity → RLSOCO Carrying Case: With a two-year warranty and robust construction, it protects your investment against years of rough handling.
• Best for replacing lost parts → Sqrmekoko 3: Comes with three pairs (six total), ensuring you always have backups for your specific JBL model.
• Best for eco-conscious buyers → RLSOCO Carrying Case: Materials are certified by RoHS/SGS, ensuring no harmful chemicals or odors.
• Best for active lifestyles → Both, but differently: Use RLSOCO to protect the case when you're not wearing them, and Sqrmekoko to ensure they stay in your ears while you move.
I would buy the RLSOCO Carrying Case first if my goal was to protect my JBL earbuds while commuting or traveling. A solid, water-resistant shell is the most practical addition to any audio setup because once your charging case is cracked or scratched, the value of the earbuds diminishes rapidly. However, if I were currently struggling with my JBL earbuds feeling loose or causing ear pain, I would immediately grab the Sqrmekoko 3 to solve that specific annoyance. Ultimately, for a laptop user looking for in ear headphones for laptop compatibility and reliability, having a durable home for your gear is the foundation, while better eartips are a secondary enhancement. In my opinion, securing your device with the RLSOCO case is the smarter initial investment, followed by upgrading the fit with Sqrmekoko later if needed.
The RLSOCO Carrying Case is water-resistant, protecting against dust and minor splashes, while the Sqrmekoko 3 eartips are made of silicone but do not claim waterproofing for the earbuds themselves.
No, you can use the RLSOCO case with your existing JBL Vibe Beam, Tune 230NC, or compatible models, but the earbuds and charging case are sold separately.
The package includes three pairs of replacement eargels, allowing you to swap them out for different sizes or keep backups for your JBL TUNE120 series.
No, these tips are specifically engineered to fit JBL TUNE120, T125, and T120 TWS earbuds and may not fit other brands securely.
