How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of headphones that does everything — wireless listening, calls, long battery life, and a wired fallback — choose Phiaton BT 390; if you need a hard-shell travel case to protect a pair of on-ear or over-ear headphones you already own, choose GEEKRIA Shield Headphones Case.
• Phiaton BT 390 — biggest strength: A complete wireless headphone in one box — 30 hours of play time, on-earpad controls with a built-in mic, multipoint pairing for two devices, and EverPlay-X so audio keeps going even when the battery dies.
• Phiaton BT 390 — biggest trade-off: It's a plastic, on-ear design with passive sound isolation rather than active noise cancellation, so it blocks sound by fit alone and won't fold down as compactly as some travel cases.
• GEEKRIA Shield Headphones Case — biggest strength: A rigid EVA hard shell with a mesh accessory pocket, sized to fit a long list of JBL on-ear and over-ear models, plus a one-year fit-or-replacement promise.
• GEEKRIA Shield Headphones Case — biggest trade-off: It makes no sound at all. It's storage only, and it fits only if your headphones measure within its interior dimensions.
• Who each is for: Buy the Phiaton BT 390 if you need headphones; buy the GEEKRIA Shield case if you already have headphones and want to keep them safe in a bag.
The BT 390 is a self-contained listening solution. Phiaton built it around a 40 mm dynamic driver with a 20 Hz to 27 kHz frequency range, 32 ohm impedance and 102 dB sensitivity — specs that point to an easy-to-drive driver with an emphasis on low-end punch, which is why the brand markets it around deep bass. It's an on-ear, closed-back design with a circular earcup shape and a plastic enclosure, weighing about 142 grams. That's light enough that on-ear clamping pressure is the main comfort variable rather than weight.
What really sets it apart is the battery story. Phiaton rates it at up to 30 hours of continuous wireless play, with a full charge taking roughly 3.2 hours. That's a full workweek of commutes on a single charge for most people. And if you forget to charge it, EverPlay-X kicks in: plug in the included cable and you keep listening or talking even with a dead battery. That's a genuinely useful safety net, and it's the kind of feature budget headphones often skip.
Connectivity is Bluetooth 4.2 with multipoint, so a phone and a tablet (or a phone and an MP3 player) can stay connected at the same time and you can switch between them. Volume and call controls live on the earcup remote, and there's a built-in microphone on the earpads for hands-free calls. There's also a 3.5 mm jack for wired listening. The whole thing folds for transport, and Phiaton backs it with a one-year warranty and US-based customer service.
Who should buy it: Anyone who wants one pair of headphones for music, podcasts, audiobooks and phone calls, and who values not having to think about charging every day. Students, commuters and remote workers who bounce between two devices will get the most out of multipoint. If you want a light, foldable on-ear set with a wired backup, this is a sensible pick.
Who should skip it: If you need active noise cancellation for flights or loud open offices, look elsewhere — the BT 390 relies on sound isolation from the earcup seal, not electronics. If you prefer the deeper cup and softer clamp of an over-ear design, an on-ear model may not suit you for long sessions. And if you already own headphones you love, this isn't the product you're shopping for at all.
The GEEKRIA Shield case solves a completely different problem: keeping a pair of headphones intact when they're not on your head. The shell is made of EVA (ethylene vinyl acetate), a firm foam-like material that holds its shape, and it's cut to interior dimensions of roughly 7.48 x 6.49 x 1.96 inches, with exterior dimensions around 7.68 x 6.5 x 1.97 inches. That's a structured, stackable case rather than a soft drawstring pouch — the kind that survives the bottom of a backpack or a carry-on.
Inside, there's a mesh pocket for cables, chargers, adapters, spare earpads and small amps. That matters more than it sounds. Cables are usually what damage headphones in transit, and keeping a 3.5 mm cord and a USB charging cable zipped into the lid means they don't tangle around the hinges or press against the drivers.
The compatibility list is long and specific: the JBL Tune series (700BT, 660BTNC, 660NC, 600BTNC, 570BT, 560BT, 520BT, 510BT, 500BT, TUNE 500, T460BT, T450BT, T450), the JBL Live series (670NC, 650BTNC, 500BT, 400BT), the Everest line (750, 710, 700, 310, Elite750NC), ELITE700, E45BT, Lifestyle E65BTNC, and the Jr310BT/Jr310/JR300BT/JR300 kids' models. GEEKRIA also states that if the case doesn't fit or breaks within one year, they'll replace or refund it.
Who should buy it: Anyone carrying on-ear or over-ear headphones in a bag, especially owners of the JBL models on that list. It's also a reasonable replacement if your original case got crushed or lost. If you travel, commute, or share a house with pets and kids, a rigid case is cheap insurance for something you use daily.
Who should skip it: If your headphones are larger than the stated interior dimensions, or you own a compact folding model with its own hard case, this adds bulk for no benefit. And if you don't have headphones yet, a case is a strange place to start.
• Best for actually listening to music → Phiaton BT 390. It's the only one of the two that produces sound.
• Best for battery life → Phiaton BT 390. Up to 30 hours of continuous wireless play, with a roughly 3.2-hour charge.
• Best for phone calls → Phiaton BT 390. On-earpad controls plus a built-in microphone, and EverPlay-X keeps calls going if the battery dies.
• Best for switching between devices → Phiaton BT 390. Multipoint Bluetooth holds two connections at once.
• Best for protecting headphones you already own → GEEKRIA Shield Headphones Case. A rigid EVA shell with a mesh pocket for cables and accessories.
• Best for travel and commuting → GEEKRIA Shield Headphones Case, if your headphones are on its compatibility list and within its interior dimensions.
• Best for light, foldable portability → Phiaton BT 390. It folds down and weighs about 142 g, so it travels without a case.
• Best for JBL owners → GEEKRIA Shield Headphones Case. The compatibility list covers a wide spread of JBL Tune, Live, Everest and Jr models.
• Best for peace of mind → GEEKRIA Shield Headphones Case, which carries a one-year fit-or-replacement promise — though the BT 390 also includes a one-year warranty.
In my opinion, these two products shouldn't really be competing — one is the thing you listen to, and the other is the thing that keeps it alive. If you're choosing today and you don't already own a suitable pair of headphones, I'd buy the Phiaton BT 390. It gives you the whole experience: wireless audio, hands-free calls, two-device pairing, 30 hours of playback, and a wired backup when the battery runs out. I'd only point you to the GEEKRIA Shield Headphones Case if you already own a compatible JBL or similarly sized on-ear/over-ear model and want to stop throwing it loose into a bag. Check the current price on Amazon for whichever one matches your situation — and if you're buying both, confirm your headphones fit inside the case's interior dimensions first.
They do different jobs, so it's not either/or in a strict sense. The BT 390 is a full wireless headphone with a mic, multipoint Bluetooth and up to 30 hours of play time. A case protects headphones you already own. Buy the BT 390 if you need sound; buy the case if you need protection.
The case's interior is about 7.48 x 6.49 x 1.96 inches and GEEKRIA lists compatibility for many JBL on-ear and over-ear models. The BT 390 is a foldable on-ear design, so it may fit, but GEEKRIA doesn't list it. Measure your folded headphones against those interior dimensions before assuming.
No. It uses sound isolation — passive blocking from the earcup seal — rather than active noise cancellation. It will soften ambient noise, but it won't silence a plane cabin or a loud office the way ANC would.
You keep listening. EverPlay-X lets you continue calls or music through a wired connection, and Phiaton includes the cable. That's a meaningful advantage over headphones that simply go silent when the charge is gone.
