If you want a pair of everyday wireless headphones with marathon battery life for music and calls, choose LORELEI Q60; if you need to turn an old 3.5mm jack — a plane seat, a gym TV, a car stereo — into Bluetooth, choose Twelve South AirFly Pro 2. These two products sit in completely different categories, and that's the most important thing to understand before you compare a single spec. One is a set of on-ear headphones. The other is a tiny Bluetooth transmitter/receiver. They solve different problems, so the "winner" depends entirely on what you're actually trying to do.
• LORELEI Q60 — biggest strength: A genuine pair of wireless headphones with a claimed 40-hour battery, Bluetooth 5.4 connectivity, a bass mode and a foldable, travel-friendly design.
• LORELEI Q60 — biggest trade-off: It's on-ear and wired-free only — no headphone jack, so it can't plug into a seat-back screen or any analog source.
• Twelve South AirFly Pro 2 — biggest strength: It converts a 3.5mm AUX jack into Bluetooth 5.3 in either direction (transmit or receive) and can pair two sets of headphones at once.
• Twelve South AirFly Pro 2 — biggest trade-off: It makes no sound on its own. It's a bridge device — you still need your own headphones or earbuds to hear anything.
• Who each pick is for: Choose the LORELEI Q60 if you want headphones. Choose the AirFly Pro 2 if you already own headphones and want to use them with wired gear.
The LORELEI Q60 is a straightforward on-ear Bluetooth headphone built around one headline number: 40 hours of battery life. For anyone who hates charging, that's a meaningful spec — the data sheet lists a roughly one-hour charge time, so a short top-up gets you back to a long stretch of listening. It uses Bluetooth (the listing cites Bluetooth 5.4 for stability and range, with the spec sheet noting 5.3), and the wireless range is listed at 10 meters, which is typical for a phone-in-pocket, walk-around-the-house setup.
The design is clearly aimed at portability and comfort. You get a lightweight ergonomic frame, an adjustable headband, and memory foam ear cushions covered in faux leather. The ear cups swivel and fold, and the package includes a carrying case plus a Type-C charging cable. The 40mm dynamic drivers, 32-ohm impedance, 110dB sensitivity and 20Hz–20kHz frequency range put it in familiar territory for a mainstream on-ear headphone. There's a built-in microphone for calls, a bass mode for extra low-end, and push-button controls on the cup. Noise control is listed as sound isolation — meaning the on-ear seal does the work passively, not active noise cancellation.
Who should buy it: Anyone who wants a single, self-contained pair of wireless headphones for commuting, studying, working out or just listening at home — and who values long battery life and a foldable, case-included design over premium audio codecs. The silver color and minimalist styling keep it neutral. It's also a sensible pick for a teen or a first set of Bluetooth headphones.
Twelve South AirFly Pro 2: Who It's For
The Twelve South AirFly Pro 2 is a different animal entirely. It's a compact Bluetooth adapter that plugs into any 3.5mm AUX jack and turns it into a wireless link. In transmit mode, it sends audio from a plane seat-back screen, gym TV, gaming console or classic stereo to your wireless headphones. Flip it to receive mode and it lets you play music from your phone through a car or boat's AUX input. That two-way flexibility is the core of what it does.
Two features stand out. First, dual pairing — it can connect two sets of Bluetooth headphones at the same time, with dedicated pairing buttons to add the second pair. That's a genuinely useful feature for sharing a movie on a flight or a road trip with a companion. Second, audio quality: it supports Bluetooth 5.3 with aptX HD Adaptive and low-latency performance, which matters if you're watching video or gaming and don't want lip-sync lag. Quick-access buttons let you adjust or mute volume right on the device. Battery life is listed as over 25 hours, and Twelve South deliberately skipped a display to maximize runtime. The unit is small — roughly 0.43" x 1.3" x 4.25" — so it slips into a tech pouch or carry-on pocket.
The spec sheet also notes compatibility with AirPods, Beats, Sony and other Bluetooth headphones, and lists supported sources including airplane entertainment systems, car stereos, gym machines, laptops and classic stereo hardware. The caveat worth knowing: the brand notes that hearing-aid compatibility isn't officially supported because Bluetooth implementations vary, and that you should recharge it periodically and avoid fully discharging it during long storage to keep the battery healthy.
Who should buy it: Frequent flyers, gym-goers, gamers and anyone with a wired audio source and a set of wireless headphones they love. If you own AirPods and want to use them on a plane's seat-back screen, this is exactly the tool for the job. It's also great for two people sharing one screen.
Side-by-Side: Which Should You Choose?
• Best for all-day music and calls → LORELEI Q60. It's a complete headphone with a mic and 40 hours of battery.
• Best for airplane and gym TVs → Twelve South AirFly Pro 2. It converts a 3.5mm jack to Bluetooth so your own headphones work wirelessly.
• Best for sharing audio with a companion → Twelve South AirFly Pro 2. Dual pairing lets two sets of headphones listen at once.
• Best for long battery life → LORELEI Q60. The 40-hour figure edges out the AirFly Pro 2's 25+ hours.
• Best for low-latency video and gaming audio → Twelve South AirFly Pro 2. aptX HD Adaptive and low-latency support matter here.
• Best for a self-contained, travel-ready package → LORELEI Q60. Foldable cups, a carrying case and a charging cable are included.
• Best if you already own great headphones → Twelve South AirFly Pro 2. It extends what you already have instead of replacing it.
• Best for a first wireless setup → LORELEI Q60. You get everything you need out of one box.
In my opinion, the right pick comes down to one question: do you need headphones, or do you need a bridge? If you need a complete set of wireless headphones for everyday listening, I'd buy the LORELEI Q60 — the 40-hour battery, foldable design, included case and built-in mic make it a genuinely useful all-rounder. But if you already own headphones you love and just want them to work with a plane screen, gym TV or car stereo, the Twelve South AirFly Pro 2 is the smarter buy — and its dual pairing and aptX HD support make it the more capable adapter of the two. They're not really competitors. Buy the one that matches the gap in your setup.
FAQ
No. It's a transmitter/receiver only — you supply your own Bluetooth headphones or earbuds. That's why it's ideal if you already own a pair you like.
Not directly. It's wireless-only with no headphone jack, so it can't plug into analog sources. That's exactly the gap the AirFly Pro 2 fills for people who want to use their headphones on a flight.
