Most gym headphones seal you off from the room. The OPN Sound Mezzo+ does the opposite. Bone conduction sends sound through your cheekbones instead of into your ear canal, so your ears stay open — you hear the trainer, the plates dropping two racks over, and the traffic on the ride home. As workout headphones go, that is the difference between tuning out and staying aware.

The neckband is why it stays put. A 26-gram titanium-and-silicone band wraps behind your head and holds through burpees, sprints and everything else that shakes normal earbuds loose. Around the neck headphones have a reputation for being bulky — this one weighs about as much as a golf ball. The IPX6 rating means heavy sweat and rain are not a problem, so one pair covers the squat rack, the trail, and the walk home in the rain.

It is also one of the few sports headphones with microphone quality good enough for real work. ENC noise-cancelling mics strip out wind, gym noise and café chatter, so a client call from the bike lane sounds like a call from your desk. Battery runs 7 hours, and 10 minutes on the USB-C cable buys back 5 — useful on the mornings you forgot to charge it. Bluetooth 5.3 holds the connection out to 33 feet without dropping.

How fast do they charge?
A 10-minute quick charge gives about 5 hours of playback; a full charge takes around 2 hours over USB-C.
Can I wear them in heavy rain?
Yes. The IPX6 rating means they're fully sweat- and rain-proof.
Are calls clear in noisy places?
Yes. ENC mics filter background noise for clearer call quality.
Will I stay aware of traffic?
Yes. Bone conduction keeps your ears open for full spatial awareness.
What warranty comes with these?
A lifetime warranty from OPN Sound. Register your Mezzo+ at opnsound.com/pages/warranty once you unbox it — registration is what activates the coverage, so do not skip it. Clavia is an authorized OPN Sound retailer, which is what makes your unit eligible; grey-market imports generally are not.
Will I be charged duties or customs fees?
No. We ship from Canadian warehouses, so there are no cross-border duties or customs charges on your order.
How long does shipping take?
We ship from four Canadian distribution centres that reach 95% of Canadian households. Orders are processed within one to two business days, and typically arrive within two to five business days. Delivery to Yukon, the Northwest Territories and Nunavut takes 5 to 10 business.
Are these good gym headphones?
Yes, and for a specific reason. The IPX6 rating handles heavy sweat, the 26 g neckband stays put through lifting and sprints, and because your ears stay open you can still hear your trainer, your spotter and the room.
Do they come with earplugs?
Yes. Earplugs are in the box. Bone conduction still delivers sound with your ears plugged, so you can shut out a noisy gym or a loud flight and keep listening.
Do they stay on during a workout?
The neckband wraps behind your head rather than sitting in your ears, so there is nothing to shake loose. At 26 grams most people stop noticing them within a set or two.
