If you want to turn the gym's old 3.5mm headphone jack into a wireless signal for the earbuds you already own, choose Twelve South AirFly Pro; if you need a single self-contained pair of open-ear headphones to wear while you lift, run or cycle, choose Gavhaio Bone Conduction Headphones.
• Twelve South AirFly Pro — biggest strength: it converts any 3.5mm aux jack into a Bluetooth 5.3 transmitter or receiver, so gym TVs, treadmills and in-flight screens can feed your own wireless headphones, with dual pairing for two listeners at once.
• Twelve South AirFly Pro — biggest trade-off: it makes no sound by itself. It is an adapter, so you must already own Bluetooth headphones and a device with an aux port to get anything out of it.
• Gavhaio Bone Conduction Headphones — biggest strength: a complete open-ear listening package in one box, with bone conduction drivers, Bluetooth 5.4, a built-in mic and up to 12 hours of playtime.
• Gavhaio Bone Conduction Headphones — biggest trade-off: open-ear sound means you hear the gym around you, and there is no headphone jack, so wired gear is off the table.
• Who each pick is for: AirFly Pro is for the person who loves their current headphones and just needs a wireless bridge; Gavhaio is for the person who wants headphones for the gym, period.
The AirFly Pro is not a pair of headphones, and that is the whole point. It is a small gold adapter that plugs into a 3.5mm aux jack and turns that jack wireless using Bluetooth 5.3. Flip it one way and it transmits audio from a screen or console to your headphones; flip it the other way and it receives audio from your phone so you can play it through a car or boat stereo. In the gym, that means the cardio machine TV, the shared audio feed on the gym floor, or a gaming console can all reach the earbuds you already trust.
Dual pairing is the standout feature for me. Two sets of Bluetooth headphones can connect at the same time, with dedicated pairing buttons for adding the second pair. If you and a training partner both want to hear the same treadmill screen, or you want to share a movie on a tablet during a long trip, that single feature is hard to beat. Audio runs over aptX HD Adaptive, and the push-button controls let you adjust or mute volume quickly.
Gavhaio Bone Conduction Headphones: Who It's For
The Gavhaio HS2 is the opposite proposition: everything you need is in the box. Bone conduction drivers sit outside the ear canal and send sound through the cheekbone, so your ears stay open. In a gym that matters more than it sounds. You can hear a spotter, a coach, a bike bell or a treadmill warning while your music keeps playing. The box includes the headphones, a head strap, a pair of earplugs for when you want to block the world out, a USB-C charging cable and a manual.
Comfort is clearly the design priority. The frame is a lightweight, flexible wraparound built from skin-friendly silicone, and Gavhaio says it fits naturally with prescription glasses, sunglasses, helmets and hats. For anyone who wears glasses and has given up on normal earbuds digging into their temples, that is a real, practical benefit rather than a marketing line. Bluetooth 5.4 handles pairing with phones, tablets, laptops and smartwatches, with a 10-metre range, and the built-in mic covers hands-free calls — useful for the delivery driver or warehouse worker who listens between sets and takes calls on the move.
Playtime is up to 12 hours, and a full charge takes about 1.5 hours via USB-C. The specs list adaptive noise cancellation and simple button controls. The honest trade-off: 8-ohm impedance and a frequency response starting at 20 Hz describe a bone conduction driver, which by nature delivers less bass isolation and less thump than an in-ear pair. There is also no headphone jack at all, so this is a Bluetooth-only device. If you want to plug into a plane seat or an old gym TV, this is not the tool. If you want one thing to grab on the way out the door, it is.
Side-by-Side: Which Should You Choose?
• Best for gym TVs and shared screens → Twelve South AirFly Pro. It is built specifically to turn a 3.5mm aux output into a wireless feed.
• Best for wearing during the workout itself → Gavhaio Bone Conduction Headphones. It is the actual headphone; the AirFly is the bridge.
• Best for battery life → Twelve South AirFly Pro. Over 25 hours versus up to 12 hours on the Gavhaio.
• Best for glasses and helmet wearers → Gavhaio Bone Conduction Headphones. The flexible silicone wraparound is explicitly designed to sit around eyewear and headgear.
• Best for sharing audio with a partner → Twelve South AirFly Pro. Dual pairing connects two sets of Bluetooth headphones at once.
• Best for charging convenience → Gavhaio Bone Conduction Headphones. USB-C, roughly 1.5 hours to full.
• Best for people who already love their earbuds → Twelve South AirFly Pro. It upgrades gear you own instead of replacing it.
• Best for a one-and-done purchase → Gavhaio Bone Conduction Headphones. Nothing else is required to start listening.
In my opinion, most people shopping for headphones for the gym should buy the Gavhaio Bone Conduction Headphones. It is a complete, self-contained product: open-ear awareness, a glasses-friendly fit, Bluetooth 5.4, a mic and up to 12 hours of playtime. I would only push someone toward the Twelve South AirFly Pro if they already own wireless headphones they love and specifically want to pull audio off a 3.5mm jack — a treadmill screen, a gym TV, a plane seat or a car stereo. That is a narrower job, but the AirFly does it very well, and its 25-plus-hour battery and dual pairing make it genuinely useful in a gym bag. If you are starting from nothing, get the Gavhaio. If you are upgrading what you already own, get the AirFly.
what is best headphones for gym
There is no single universal answer, because it depends on whether you want open-ear awareness or isolation. The Gavhaio Bone Conduction Headphones suit most gym sessions because the open-ear design keeps you aware of your surroundings, while the AirFly Pro is the better pick if your gym's equipment only offers a 3.5mm aux output.

For lifting, running, cycling and hiking, the Gavhaio HS2 covers it: bone conduction drivers, a flexible silicone wraparound frame that fits with glasses and helmets, Bluetooth 5.4 and up to 12 hours of playtime. If your gym has wired screens you want to listen to wirelessly, the AirFly Pro handles that instead.

Forums tend to split the same way the specs do: some people want fully open ears for safety and comfort, others want to keep using the earbuds they already own. The Gavhaio addresses the first group directly, while the AirFly Pro is the adapter answer for the second group — it feeds your existing Bluetooth headphones from a 3.5mm jack.

Look at fit and battery first. The Gavhaio's skin-friendly silicone frame and light wraparound design are built for extended wear, and 12 hours of playtime plus USB-C charging covers a week of sessions. The AirFly Pro is not a headphone, but its 25-plus-hour battery and dual pairing make it a strong companion if you already have a pair you like — just check the current price on Amazon before deciding.
