If you want a separate, hard-sided travel case for Beats Powerbeats Pro accessories while studying, choose RLSOCO Carrying Case; if you need a fitted protective cover for a Bose QuietComfort earbuds charging case, choose Aircawin Bose QuietComfort Earbuds. They solve different problems: RLSOCO stores and organizes a charging case and accessories, while Aircawin stays on a compatible Bose charging case.
For true wireless earbuds for studying, choose based on which earbuds you own and whether you need a carry case or an everyday cover.
• RLSOCO’s biggest strength: A hard EVA case with a soft interior, divider, and carry strap for a Powerbeats Pro charging case and accessories. Trade-off: It is a separate storage case, not a protective cover that stays on Bose earbuds.
• Aircawin’s biggest strength: A clear glitter TPU cover for specified Bose QuietComfort charging cases, with a carabiner, cleaning pen, and visible front charging indicator. Trade-off: It is a soft cover, not a roomy travel organizer for a charging case and accessories.
• Choose RLSOCO if you own Beats Powerbeats Pro and want a dedicated place to store or carry the charging case and accessories.
• Choose Aircawin if you own one of the listed Bose QuietComfort models and want a fitted cover that can remain on its charging case.
RLSOCO is an accessory storage case, not a pair of earbuds and not a replacement charging case. It is designed for the Beats Powerbeats Pro charging case, including use with a skin cover, and has room for accessories. Inside, a soft lining and central divider help keep items snug and reduce contact between them. The hard EVA outer shell gives it a more structured feel than a flexible cover.
That format suits someone who moves between a desk, library, and backpack and wants the Powerbeats Pro charging case and small accessories kept together. The built-in handle strap makes it easier to carry by hand, while the separate enclosure can keep stored items away from dust. If your earbuds come along for a study session and then get packed away, this is the more complete storage solution of the two.

The main limitation is compatibility: it is made for Powerbeats Pro, not the Bose QuietComfort models covered by Aircawin. It also adds a separate case to carry, rather than fitting over the charging case for daily use. The product listing specifies case only; the earbuds and accessories are not included. If you want a slim cover that stays attached to a Bose charging case, RLSOCO is the wrong shape of solution.
Aircawin is a protective cover for the charging cases of Bose QuietComfort Earbuds II (2022), QuietComfort Ultra (2023), and Bose Ultra Earbuds 2nd Gen (2025). The flexible TPU shell is designed to fit around the charging case rather than hold it inside a larger travel organizer. Its clear finish with embedded silver glitter keeps the case visible while adding a distinct decorative look.
For everyday carry, the two-part design leaves access to the pairing button, and the front LED indicator remains visible while charging. A carabiner can attach the covered case to a bag, keychain, or belt loop. The included cleaning pen has a charging-hole brush, a plush brush, and a metal nib, giving the package a small maintenance tool as well as the cover.
This is the more relevant pick if you already own a compatible Bose model and want a cover intended to protect its charging case from scratches, dust, smudges, bumps, and drops without adding much bulk. Its trade-offs are just as important: it does not organize accessories in a separate compartment, and it is not designed for Powerbeats Pro. The Bose earbuds and charging case are not included. Choose another option if you prefer a plain appearance or need a hard-sided case for storing several items together.
• Best for organizing a Powerbeats Pro charging case and accessories → RLSOCO Carrying Case. It has a dedicated interior and a divider to separate stored items.
• Best for a fitted cover on a Bose QuietComfort charging case → Aircawin. Its listed compatibility includes QuietComfort Earbuds II, QuietComfort Ultra, and Bose Ultra Earbuds 2nd Gen.
• Best for structured storage in a bag → RLSOCO. Its hard EVA shell and soft-lined interior make it a standalone storage case.
• Best for leaving a cover on the charging case → Aircawin. Its flexible TPU cover is designed to fit around compatible Bose cases.
• Best for carrying by a strap → RLSOCO. It includes a handle strap for carrying the case by hand.
• Best for attaching the covered case to a bag or keychain → Aircawin. It comes with a carabiner.
• Best for seeing the charging indicator through the cover → Aircawin. The front LED indicator is described as visible while charging.
• Best for a low-key protective design → RLSOCO. Its grey, solid design is more understated than Aircawin’s clear glitter finish.
These are not interchangeable products, so the first decision is compatibility. If you have Powerbeats Pro, RLSOCO is the option here that fits the stated need. If you have one of Aircawin’s specified Bose models, its cover is the one designed for that charging case. After that, think about how you carry your earbuds: packed away with accessories, or kept in their case with a cover on.
My Verdict
I would choose RLSOCO if I owned Powerbeats Pro and wanted a dedicated place for the charging case and accessories between study sessions. Its hard shell, lined interior, divider, and carry strap make it the more useful storage setup for that specific job. For studying, I prefer the organization of a standalone case when I’m packing more than the charging case alone. If I owned a compatible Bose model instead, I’d choose Aircawin for an attached cover and carabiner.
Both products are accessories; neither includes earbuds. RLSOCO is a standalone case for Beats Powerbeats Pro and accessories, while Aircawin is a cover for specified Bose QuietComfort charging cases.
It depends on the earbuds you own and what you need to carry. RLSOCO has space for a Powerbeats Pro charging case and accessories; Aircawin covers a compatible Bose charging case and includes a carabiner.
Neither product provides earbuds or call features, so neither can establish call clarity. Choose between them based on whether you need the RLSOCO storage case for Powerbeats Pro or the Aircawin cover for a compatible Bose case.
Its listed compatibility includes Bose QuietComfort Ultra (2023) and Bose Ultra Earbuds 2nd Gen (2025), as well as QuietComfort Earbuds II (2022). The earbuds and charging case are not included.
