Disclaimer: I received my Aftershokz XTrainerz to review as part of being a BibRave Pro. Learn more about becoming a BibRave Pro (ambassador), and check out BibRave.com to review, find, and write race reviews!

The Aftershokz Xtrainerz finally dropped in the US last week and the BibRave Pros are getting in all the musical laps fun. The same great open ear comfortable design has been made specifically for your underwater enjoyment with 4GB of mp3 storage, IP68 waterproof rating, and an 8-hr battery life. The unboxing was definitely like early Hanukkah for me! So far, I’ve had them on one swim session and they’re even more magical than I had imagined. I’ll be back with more details after a few more swim/run/bike sessions, but I can already tell you that these are life-changing. Grab a pair yourself using code BRBUNDLE for $50 off the endurance bundle at www.bibrave.aftershokz.com.
