How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to protect a pair of JBL Live Free 2 or Wave 300 TWS earbuds you already own, choose RLSOCO Case; if you need a complete wireless earbuds setup with Bluetooth 5.4, an LED battery display and IP7 water resistance, choose Btootos Earbuds.
These two products sit in completely different corners of the audio world, which is exactly why the comparison trips people up. One is a hard shell that guards a charging case you already have. The other is the whole package — drivers, mic, battery and case included. Once you see that split clearly, the decision stops being confusing and becomes obvious.
• RLSOCO Case — biggest strength: A hard, water-resistant EVA-and-polyester shell that shields a JBL Live Free 2 or Wave 300 TWS charging case from knocks, shock, scratches, dust and moisture, with a carabiner for clipping onto a bag.
• RLSOCO Case — biggest trade-off: It is case only. No earbuds, no cable, no eartips, no electronics. If you don't already own the JBL model it's built for, it does nothing for you.
• Btootos Earbuds — biggest strength: A full true-wireless kit: Bluetooth 5.4 with up to 15 m range, 14.2 mm dynamic drivers, ENC call noise reduction, a 36-hour total battery figure and an IP7 waterproof rating.
• Btootos Earbuds — biggest trade-off: Its noise control is passive (seal and sound isolation), not active cancellation, so it won't silence a plane cabin the way ANC does.
• Who each pick is for: RLSOCO Case → someone who already owns JBL Live Free 2 or Wave 300 TWS and wants rugged, pocketable protection. Btootos Earbuds → someone who needs working earbuds today, for calls, sport and daily listening.
The RLSOCO Case is a single-purpose accessory, and it's honest about that. It's built for the JBL Live Free 2 and Wave 300 TWS charging cases, plus room for a cable and eartips. The shell is a hard EVA enclosure wrapped in polyester, and RLSOCO says the fabric, lining and EVA compartments carry RoHS and SGS certification. The EVA is a thicker grade than typical storage cases, which is the part that matters most — thin EVA collapses under pressure in a backpack, while a stiffer grade holds its shape and keeps the charging case from getting crushed.
In daily terms, this is the case you toss in a purse, a jacket pocket, a backpack or a handbag and stop thinking about. The carabiner lets you clip it to a bag strap instead of digging for it. Water resistance and dust resistance are both claimed, so a rainy commute or a dusty gym bag isn't a disaster. It weighs almost nothing on its own, and RLSOCO backs it with a two-year warranty covering manufacturing defects.
Who should buy it: anyone who already owns JBL Live Free 2 or Wave 300 TWS earbuds and treats the charging case as the fragile part of the kit. Charging cases scratch, crack and take the impact when a bag gets thrown around, and that's the failure this product exists to prevent.
Who should skip it: anyone who doesn't own those specific JBL models, and anyone hoping this is a pair of earbuds. It isn't. It's an empty, well-made home waiting for a device you supply.
The Btootos Earbuds (model A90, sold as the A90 Pro) are a self-contained true-wireless package in blue. The headline spec is Bluetooth 5.4, which brings faster, more stable transmission, low latency and a stated range of up to 15 metres — enough to leave your phone on a desk and walk to the other end of a room or gym floor. Pairing is automatic and it works across phones, laptops and other Bluetooth devices.
Sound hardware is a step above budget-basic: dual 14.2 mm low-distortion composite dynamic drivers, a built-in high-resolution decoder, and AAC plus SBC codec support, with 32 ohm impedance. The 14.2 mm driver size is the number to remember — larger drivers generally move more air and give bass more room to breathe, which lines up with the bass-forward positioning. For calls, ENC (environmental noise cancellation) works on the microphone side to pull your voice forward on the other end of the line. Note the distinction: the noise control listed is passive noise cancellation and sound isolation, meaning the in-ear seal blocks some outside sound. There's no active cancellation claiming to erase engine drone.
Battery is the other strong card. Btootos quotes 6–8 hours per charge and up to 30 hours from the charging case, for a 36-hour combined figure. The case holds a 300 mAh battery and recharges in about 1.5 hours over USB-C. An LED display on the case shows the charge level of both the case and the earbuds, which removes the guesswork of "are these actually charged?" Touch controls handle play/pause, track skipping, calls and the voice assistant without reaching for your phone.
The fit story is ergonomic in-ear with soft silicone tips in three sizes (S/M/L), and an IP7 waterproof rating with an ultra-light nano coating for dust and rain resistance. Sweat and weather are covered. In the box: the earbuds, the charging case, the three tip sizes, a USB-C cable and a manual, with a two-year warranty.
Side-by-Side: Which Should You Choose?
• Best for protecting earbuds you already own → RLSOCO Case. It's purpose-built for the JBL Live Free 2 and Wave 300 TWS charging cases.
• Best for getting earbuds in the first place → Btootos Earbuds. The RLSOCO Case contains no electronics at all.
• Best for battery life → Btootos Earbuds. 6–8 hours per charge, up to 30 hours from the case, 36 hours combined, recharged over USB-C in roughly 1.5 hours.
• Best for impact and weather protection of a charging case → RLSOCO Case. Hard EVA shell, polyester exterior, water and dust resistance, carabiner for bag carry.
• Best for calls → Btootos Earbuds. Dual 14.2 mm drivers plus ENC microphone noise reduction for clearer voice pickup.
• Best for quieting a noisy commute → Btootos Earbuds, with a caveat. Its cancellation is passive seal-based isolation; if you need active cancellation, neither sheet promises it.
• Best for workout and rain use → Btootos Earbuds. IP7 waterproofing with a nano coating, plus three silicone tip sizes for a stable in-ear fit.
• Best for travel organisation → RLSOCO Case. Keeps the charging case, cable and spare eartips together in one compact clipped-on pouch.
In my opinion, most people searching this comparison should buy the Btootos Earbuds, because it's a finished product — Bluetooth 5.4, 14.2 mm drivers, ENC calls, 36 hours of combined battery, IP7 water resistance and a touch-controlled LED case. It covers listening, calling and charging in one purchase. I'd only steer you to the RLSOCO Case if you already own JBL Live Free 2 or Wave 300 TWS earbuds and your real problem is a charging case that keeps getting scratched, crushed or rained on. Buy the accessory to protect a device you have; buy the earbuds when you need the device.
No. It's a hard protective case only — no earbuds, cable or charging electronics are included. It's designed to hold the JBL Live Free 2 or Wave 300 TWS charging case, a cable and eartips.
No. The listed noise control is passive noise cancellation and sound isolation, meaning the in-ear seal blocks some outside noise. The ENC feature works on the microphone side to improve call clarity, not to cancel ambient sound for the listener.
Btootos quotes 6–8 hours of use per charge, with the charging case adding up to 30 hours, for a combined figure of 36 hours. The case recharges over USB-C in about 1.5 hours.
They carry an IP7 waterproof rating with an ultra-light nano coating, described as dust and rain proof. That covers sweat, rain and splashes, though IP7 isn't a claim of full submersion durability for long periods.
The RLSOCO Case. But check the current price on Amazon and confirm your model first — it's built for the JBL Live Free 2 and Wave 300 TWS, and it won't fit other charging cases.
