How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless, over-ear headset that doubles as an FM radio and keeps you untethered while you study, choose RETRADEKING Over-Ear FM Headphones; if you need a wired, non in ear design built around safe listening and all-day comfort for studying, choose ibrain Air Tube Headphones. That's the short version. The longer version comes down to one question: do you want to roam free with Bluetooth and FM, or do you want a corded, air-tube set that never needs charging?
• RETRADEKING biggest strength: Wireless Bluetooth 5.3 plus FM radio, a built-in rechargeable battery rated for 8–10 hours, and a USB transmitter for TVs and PCs that lack Bluetooth.
• RETRADEKING biggest trade-off: It's a 300 g over-ear headset with no microphone mentioned, so it's for listening, not calls — and you'll need to charge it.
• ibrain biggest strength: A wired air-tube design with no loudspeaker in the earpiece, in-line volume and mic controls, and an adjustable, foldable headband for adults and kids.
• ibrain biggest trade-off: It's wired only via 3.5 mm jack, so there's no Bluetooth or FM freedom, and some phones may need an adapter.
• Who RETRADEKING is for: Anyone who wants a wireless over-ear headset for TV, PC and long study sessions without cables.
• Who ibrain is for: Anyone who prefers a corded, non in ear fit and wants the air-tube structure with in-line controls.
The RETRADEKING set is a wireless over-ear headset first and a radio second, and that combination is unusual. You get Bluetooth 5.3 with a stated range of 10–15 m, plus an FM radio band running 88–108 MHz. That means you can switch between streaming from your phone and tuning into a station without swapping devices. For studying, that flexibility matters: some people focus better with background radio, others with a playlist, and this headset covers both.
Who should buy it? If you want the best wireless headset for studying — one that works with your phone, laptop and TV, and adds FM as a bonus — this is the pick. Who should skip it? If you need a microphone for calls or online classes, note that no microphone is listed, so look elsewhere if talking is the point. Also skip it if you'd rather never think about charging.
ibrain Air Tube Headphones: Who It's For
The ibrain Air Tube Headphones take the opposite approach: wired, simple, and built around a specific idea. There's no loudspeaker inside the earpiece. Instead, an air tube carries the sound to your ear, which creates physical distance between your phone and your head. The company frames this as a "safe listening mode" and notes it has focused on air-tube headphones for over 20 years. Whether or not you buy into the health angle, the design itself is the reason people seek these out — it's a genuinely non in ear structure.
The practical side is solid. You get in-line controls for volume and mic muting, so you don't have to dig into settings to adjust anything. The headband is adjustable for different head sizes and rated for both adults and kids, and the soft on-ear pads plus foldable frame make it easy to toss in a backpack. The connection is a standard 3.5 mm jack, which is widely compatible — though the brand explicitly warns to check your jack type first, since some phones need an adapter. Durability gets a mention too, via metal-shielded, multi-strand copper wiring meant to handle daily wear. The warranty is listed at 1 year.
Who should buy it? If you want a corded set that never needs charging, folds flat, and uses an air-tube design rather than speakers sitting in your ear canal, this fits. Who should skip it? Anyone who wants Bluetooth, FM, or cable-free movement. This is a plug-in-and-listen product, full stop.
Side-by-Side: Which Should You Choose?
• Best for radio listening → RETRADEKING Over-Ear FM Headphones. The built-in FM tuner covers 88–108 MHz, so over-the-air stations are an option.
• Best for a no-charging routine → ibrain Air Tube Headphones. Wired via 3.5 mm, it draws nothing from a battery.
• Best for the air-tube, non in ear concept → ibrain Air Tube Headphones. No loudspeaker in the earpiece by design.
• Best for TV and PC without Bluetooth → RETRADEKING Over-Ear FM Headphones. The bundled USB transmitter works with 3.5 mm or RCA outputs.
• Best for sharing or travel → ibrain Air Tube Headphones. The adjustable band fits adults and kids, and the frame folds for a backpack.
• Best for long sessions away from a plug → RETRADEKING Over-Ear FM Headphones. The 8–10 hour rated battery covers a full study day.
• Best for lightweight simplicity → ibrain Air Tube Headphones. Fewer parts, no charging, in-line controls right on the cable.
I'd buy the RETRADEKING Over-Ear FM Headphones. For studying, the wireless range, the 8–10 hour battery, the FM tuner and the USB transmitter cover more situations — phone, laptop, TV, radio — than a wired-only set can. In my opinion, that versatility is worth the charging habit. The ibrain Air Tube Headphones are the better call if you specifically want the air-tube design, a foldable frame, or a set that never needs a battery. But if I had to pick one for the best wireless headset for studying, it's the RETRADEKING.
FAQ
how do non ear headphones work
Non in ear headphones sit outside or over the ear canal rather than inside it. The ibrain design pushes this further: there's no loudspeaker in the earpiece, so an air tube carries sound to your ear. The RETRADEKING model uses a standard over-ear cup with 40 mm drivers instead.
This product pair isn't in ear at all, which is the point. The RETRADEKING uses an over-ear cup with a multi-level adjustable headband; the ibrain uses soft on-ear pads with an adjustable band that fits adults and kids. Adjust the band until the pads sit comfortably and settle in.
what are non in ear headphones called
They're usually described as over-ear or on-ear headphones, since the earpiece rests on or around the ear instead of inside the canal. Air-tube and open-ear are related terms for designs that keep the ear canal clear, like the ibrain set here.
what are the best open ear headphones
That's a personal call, but for a study setup I'd weigh the trade-offs. If you want wireless freedom, FM and a long battery, I recommend the RETRADEKING Over-Ear FM Headphones. If you want a wired, air-tube over-ear design that folds and never needs charging, I recommend the ibrain Air Tube Headphones. Check the current price on Amazon for whichever fits your routine.
