How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a protective silicone cover that keeps your JBL Live Pro 2 charging case safe and clipped to your gear, choose kwmobile Design Cover; if you need a complete set of true wireless earbuds with Bluetooth 5.3 and an IPX7 sweatproof rating, choose Generic Air31.
• kwmobile Design Cover — biggest strength: Soft silicone shell with a carabiner clip that protects a JBL Live Pro 2 charging case from scratches, scuffs and dust while staying slim and lightweight.
• kwmobile Design Cover — biggest trade-off: It is an accessory only, not earbuds. If you do not already own JBL Live Pro 2 TWS earbuds, it has nothing to cover.
• Generic Air31 — biggest strength: A full true wireless earbud package with 6mm dynamic drivers, Bluetooth 5.3, IPX7 water resistance and a charging case that adds extra charges on the go.
• Generic Air31 — biggest trade-off: Fit and isolation depend entirely on the silicone eartips, and the spec sheet is thinner on premium materials than the case cover's soft silicone build.
• Who the kwmobile Design Cover is for: Someone who already owns JBL Live Pro 2 earbuds and wants to protect and carry the charging case hands-free.
• Who the Generic Air31 is for: Someone who needs a complete, sweat-resistant pair of earbuds for running, gaming, calls and everyday listening.
The kwmobile Design Cover is a silicone pouch made specifically for the JBL Live Pro 2 TWS charging case. It measures 2.56 x 2.36 x 0.51 inches and weighs just 17 grams, so it adds protection without bulking up the case in your pocket or bag. The soft silicone is there to absorb the small stuff: scratches, scuffs, dust and the general wear that comes from tossing a case into a backpack every day. The white and black color options keep it looking clean rather than loud.
Who should skip it? Anyone who does not own JBL Live Pro 2 TWS earbuds. Compatibility is limited to that one model, so this is not a universal case. If you are still deciding on earbuds, this is not the product to start with. But if you already have the JBL Live Pro 2 and the charging case is the part that takes the beating, this cover is a sensible, low-effort way to protect it.
Generic Air31: Who It's For
The Generic Air31 is a true wireless stereo in-ear earphone aimed at people who want a complete listening setup without overthinking it. It uses Bluetooth 5.3 with a stated range of up to 30 feet, so you can leave your phone on a bench or desk and keep listening. The 6mm neodymium dynamic drivers are tuned to deliver dynamic bass and clear treble, which is the kind of sound profile that works well for gym playlists, podcasts and casual gaming. Impedance is listed at 80 ohm.
Durability is a real selling point here. The IPX7 waterproof rating means the earbuds can handle sweat or a quick splash, so running, lifting or training in damp conditions is not a problem. The soft silicone eartips come in multiple sizes to help you get a snug seal, which matters both for comfort and for keeping the buds in place during movement. Controls are handled on the earbuds themselves — media, calls and voice assistant activation are all a button press away on either side. Active Noise Cancellation is listed among the noise control features, and the built-in microphone supports hands-free calls.
Battery life is straightforward: up to 5 hours of playtime on a single charge, with the compact charging case providing four additional charges for a total of around 20 hours. A full charge takes about an hour. The earbuds are made from plastic ABS + PC, come in blue, and ship with a protective case. The listed package includes four items and a 1-year warranty.
Who should skip it? If you want premium materials, a metal build or a more established brand name, this is a budget-oriented generic product and the spec sheet reflects that. If you already own a great pair of earbuds, you do not need these.
• Best if you already own JBL Live Pro 2 earbuds → kwmobile Design Cover. It is built for exactly that case and nothing else.
• Best if you need earbuds at all → Generic Air31. The kwmobile cover does not produce sound; it only protects a case you already have.
• Best for protecting against scratches and dust → kwmobile Design Cover. Silicone shell, 17 g, with a charge-through opening.
• Best for workouts and sweat → Generic Air31. The IPX7 rating is the deciding spec here.
• Best for carrying hands-free → kwmobile Design Cover. The carabiner clip attaches to bags, belts and keys.
• Best for battery life → Generic Air31. Up to 5 hours per charge plus roughly 20 hours total with the case.
• Best for calls and voice assistant use → Generic Air31. Built-in microphone, media controls and voice control.
• Best for a slim, lightweight add-on → kwmobile Design Cover. At 17 g and 0.51 inches thick, it barely changes the feel of the case.
In my opinion, these two products do not compete — they solve different problems, and the right pick depends entirely on what you already own. If you have JBL Live Pro 2 earbuds and your charging case is getting scuffed in your bag, I would buy the kwmobile Design Cover. It is cheap insurance with a clip that genuinely makes carrying easier. If you do not own earbuds yet, I would buy the Generic Air31 instead, because it is the only one of the two that actually plays music. For most readers landing on this page, the Air31 is the more complete purchase.

Take the earbuds out of the charging case and they should enter pairing mode automatically. On your phone, open Bluetooth settings, find the Air31 listing and tap it. The Generic Air31 uses Bluetooth 5.3 with a range of up to 30 feet, so keep your device close during the first connection.

"TWS" simply means true wireless stereo — two independent earbuds with no cable between them. The Generic Air31 fits that description, pairing wirelessly over Bluetooth 5.3 and charging from its own case. If you were looking for a case cover instead, the kwmobile Design Cover is the accessory for JBL Live Pro 2 TWS earbuds.
