What are Bone Conduction Headphones?

It will change the way you think about audio.

Traditional headphones create sound waves that travel through the air and enter your ears, where your eardrums pick up the vibrations.

Bone Conduction is different - it sends vibrations into your skull bones, bypassing your eardrum, and transmits them directly to your inner ear, where the brain interprets them as sound.

I LOVE MY H2O AUDIO TRI 2 PRO HEADPHONES

As a dedicated triathlete, the H2O Audio TRI 2 PRO with PLAYLIST+ has become an essential part of my training. Its design caters perfectly to my multi-sport needs, especially swimming. Here's my personal take:

*Bone Conduction Technology:
While the open-ear design is ideal for situational awareness in general, I primarily use these headphones with silicone earplugs during swims and indoor bike trainer sessions. This combination creates a focused audio experience, blocking out distractions while still enjoying my music.
*Waterproof Design (IPX8):
This is non-negotiable for me. The reliable waterproofing allows me to seamlessly transition from land to water without worry.
*PLAYLIST+ Feature:
This is a game-changer! The ability to record audio directly onto the device is invaluable, especially during long swims where Bluetooth is unreliable. However, I've found the recording process itself to be a bit time-consuming, and labeling tracks is definitely a challenge. If you mess up, you have to restart the whole process.
*Bluetooth 5.3 & Built-in MP3 Player:
Both provide flexibility. I appreciate having the option to stream music or rely on the onboard storage.
*Sound Quality:
As expected with bone conduction, the sound is adequate for training, but it's not audiophile-grade. For my purposes, it gets the job done.
*Button Controls:
I've found the button interface to be somewhat cumbersome. Switching between folders, adjusting volume, and even powering off requires a learning curve.
*PLAYLIST+ Recording:
As stated above, this is a great feature, but the process is time consuming, and error prone.
Overall:

The H2O Audio TRI 2 PRO with PLAYLIST+ is a robust and reliable training companion for triathletes. The waterproof design and offline playback are outstanding features. While the controls and recording process could be more user-friendly, the benefits outweigh the drawbacks. If you're a triathlete seeking a durable and versatile audio solution, these headphones are a worthwhile investment, especially if you plan to use ear plugs while swimming or training indoors.

Can't keep on while swimming

The function and sound of the headphones is great but while swimming I can't keep them from coming off. If I flip turn or streamline they come off which has been frustrating. I'm not sure if maybe I just have a small head or something. great for running and biking but I prefer non bone conduction for those activities.

Very heavy on the bass, and too big for me....

The Tri-Pro device is a must-have for swimmers!

The sound quality of the device is excellent, and its sleek design makes it particularly well-suited for swimming activities. However, one challenge I faced was downloading music onto the device. To resolve this issue, I reached out to customer service for assistance. I was impressed by their responsiveness and the high quality of support they provided.
