- Which is better for swimming?
- Both are waterproof bone conduction sets. The OpenSwim Pro carries an IP68 rating, while the TRI 2 is rated to 12 feet (3.6 meters). Pick the TRI 2 if you want music without a phone, since it stores up to 2,000 songs.
- Which has better battery life?
- The TRI 2 lists 6 to 9 hours of playtime. The OpenSwim Pro lists 6 days of standby and a 1.5-hour recharge but no playtime figure, so the TRI 2 is the safer bet for long sessions.
- Is the OpenSwim Pro worth the extra?
- At $169.95 at Distritech as of November 2, 2026, it buys Bluetooth 5.4, multipoint pairing, and faster charging. If you mainly want stored music for swims, the TRI 2 covers that with more storage.
- Can I take calls on either?
- Both have integrated microphones, and the TRI 2's mic is listed as waterproof. The OpenSwim Pro adds multipoint pairing so you can switch between two connected devices.
- Which is lighter to wear?
- The TRI 2 weighs 1.12 oz with a soft silicone finish. Shokz does not list a weight for the OpenSwim Pro, so try both if weight matters.
- Do either block out noise?
- No. Both are open-ear bone conduction designs with no active noise cancellation, so you hear traffic and pool noise around you.
