Which is better for swimming?

The H2O Audio Tri 2. It is IPX8 rated to 12 ft and plays from its 8 GB memory underwater. The Shokz is only IP55 and needs a Bluetooth connection.

Which has the better microphone for calls?

The Shokz OpenComm2. Its noise-canceling boom mic with DSP and one-touch mute is built for calls. The Tri 2 has a waterproof built-in mic with no boom.

Which lasts longer on a charge?

The Shokz, at up to 16 hours of talk time and 8 hours of listening. The Tri 2 runs 6 to 9 hours depending on use.

Is the Tri 2 worth it if I do not swim?

Only if you want phone-free music from its 8 GB storage. For calls and all-day wear the Shokz is the better fit.

Can the Shokz be used for running?

Yes. The open-ear design leaves both ears uncovered and it is sweat resistant at IP55, though it is not meant for swimming.

Do either have active noise canceling?

No. Both are open-ear bone conduction designs. The Shokz cancels noise on the mic side, not in your ears.

Shokz OpenComm2 UC Bone Conduction Headset vs H2O Audio Tri 2

Buy the Shokz OpenComm2 if you need a work headset: its boom mic, 16-hour talk time and USB adapter make it the better call tool. Buy the H2O Audio Tri 2 if you swim or want music without a phone, since it is IPX8 waterproof to 12 ft and holds 8 GB of MP3s. The Shokz is the stronger all-day office and running pick; the Tri 2 is the only one of the two you can submerge.
