IO Breezy Bone Conduction Headphones Review: Affordable Open-Ear Running Audio

Introduction

Open-ear sports headphones have gone from niche to genuinely mainstream, and the IO Breezy bone conduction headphones (also known as the IO iT Geo 1) are a strong example of why. They promise many of the features found on premium rivals, including Bluetooth 5.3, an IPX6 waterproof rating and a lightweight alloy frame, at a much more affordable price of $99, around £80 in the UK.

After plenty of listening time on long runs and podcasts, here is how they performed in real use.

Why Open-Ear Headphones Make Sense for Runners

Traditional in-ear headphones seal the ear canal, which is not ideal when you are sharing roads with traffic. You can still hear your music or podcast, but you lose the ambient sounds around you: cars, pedestrians, other runners.

Bone conduction headphones solve that by hanging over the top of the ear and keeping the ear canal open. You get your audio and your surroundings at the same time, which makes for a much safer listening experience on the road.

Construction and Key Features

The IO iT Geo 1 is built from CNC aluminium alloy and comes in a grey and silver colorway, with an all-black option also available. Connectivity is handled by the latest Bluetooth 5.3, so there are no wires to worry about and pairing is quick.

Audio benefits from professional-grade tuning and clever sound directional transmission technology, which is designed to restore the full range of sound and improve overall quality. The headphones carry an IPX6 waterproof rating, so sweaty workouts and wet winter runs are no problem.

Battery life is rated at six and a half hours of music or calls per charge. Charging is handled by a handy magnetic charging station: pop the headphones in and a full charge took only a couple of hours. A small headset button lets you answer calls, pause music and summon your voice assistant.

Notably, the IO headphones offer better Bluetooth connectivity and a higher waterproof rating than the pricier Shokz OpenRun Pro, which retailed at £60 more, which is impressive for the price point.

Ease of Use

Pairing to a phone via Bluetooth 5.3 took a couple of seconds, which is refreshing for new tech. Powering on is a long press of around three to five seconds on the headset button, and a small voice confirms the status, backed by a flashing light indicator on the bottom of the unit.

Taking calls or pausing music mid-run is a single quick press. The only real gripe here is volume: there is no adjustment button on the headphones, so you have to reach for your phone. The voice assistant on the Shokz OpenRun Pro is also a touch clearer.

Comfort

At just 36 grams, you can barely feel these on your head, which makes them easy to forget about over long training runs, races or rides. The section that hangs over the ear is covered in a soft tactile rubberized coating that stays comfortable and helps limit movement.

The ergonomic design holds firm too: vigorous head shaking and jumping produced no movement at all.

Sound Quality and Performance

This is where budget headphones usually fall apart, but the IO unit holds up well. The directional sound generation technology and diaphragm component, which collects both high and low-end frequency sound waves, deliver a clear, crisp sound with a sharp treble.

For podcasts and audiobooks on the move, the sound is more than adequate. If you want loud, bassy music for hard workouts, the Shokz OpenRun Pro offers a bit more bass and volume, but for spoken-word listening the difference is hard to argue with at half the price.

Buying Advice

If your priority is safe road running, long comfy sessions, and a fair price, the IO Breezy is an easy recommendation. Look elsewhere only if you need on-device volume controls or maximum bass for high-energy playlists. Just keep in mind the six-and-a-half-hour battery limit on very long days out.

Conclusion

The IO Breezy (IO iT Geo 1) is a comfortable, lightweight and distinctive-looking pair of bone conduction sports headphones that covers the essentials very well. With solid sound, excellent Bluetooth 5.3 connectivity, an IPX6 rating and magnetic charging at around $99 or £80, it is a compelling alternative to more expensive rivals.
