Letting the Xtrainerz Out of the Box

Disclaimer: I received 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!

This past month or so I had the opportunity to test out a pair of Aftershokz Xtrainerz wireless bone conduction headphones. What the heck is bone conduction you may ask? I wondered the same thing when I first heard of them. The Aftershokz development team has created what is in my opinion an entirely new category of sound delivery by sending mini vibrations via the cheekbones to the inner ears. By doing so, the patented design of Aftershokz bone conduction headphones are able to deliver high quality sound without covering or blocking the ears. What does this mean? Greater comfort and situational awareness! If you’ve worn earbuds for a long period of time you’re familiar with how uncomfortable they can become. Aftershokz solves this issue by not requiring anything to be inserted into the ear; the headphones rest comfortably over the ear and on the cheekbone. This also allows the user to still hear what’s going on around them increasing their awareness of their surroundings and quite possibly their safety. These are two huge benefits of the Aftershokz bone conduction sound delivery system.

If you’re already an Aftershokz believer, you may be asking what the Xtrainerz offer that I’m not already getting with my older model of Aftershokz headphones? The Xtrainerz offer two major differences:

1: They are waterproof!

Xtrainerz are IP68 rated. IP68 is a rating assigned to products after laboratory testing to measure ingress protection (IP). The two numerals are ratings for IP from solids (dust) and liquids (water). The 6 indicates a rating of “dust tight; complete protection against contact.” The 8 indicates liquid protection against “continuous immersion in water”. A full explanation of the ratings can be found on the DSM&T site. 

What does Xtrainerz being waterproof do for you? How about music for cross training activities in the pool? Or getting caught in the rain in the middle of a run and not having to worry about getting your headphones into a waterproof bag? Both huge bonuses in my book.

2: They offer 4 GB of internal storage, but lack bluetooth connectivity

This change is a trade off so some may see it as an upgrade while others see it as less desirable. I can see both sides of the argument. I can’t say anything negative about the conveniences of bluetooth connectivity. However, I can see some benefits of opting for internal storage. The main benefit of internal storage for me is the fact that I don’t have to carry any other device if I want to listen to music while running, biking, or swimming. All I need is my Xtrainerz and I’m ready to go. This simplifies planning for having music during long trail ultras. I don’t have to worry about having my phone or its battery level to have music readily available when I feel the need for some extra motivation from it.

This leads to the second benefit I found of internal storage; it’s one less battery to worry about. If you carry your phone during runs to use for calls in case of emergency, as a GPS device or to check stored maps, or just to take pictures of cool stuff while out exploring new trails, battery life is always a concern. If you’re draining your phone battery because your streaming to your bluetooth headphones, you may not have any juice left for those other uses when you need it. With winter and colder temperatures just a season away, battery life becomes even more of a precious commodity.

Xtrainerz in the shower! Why not!

In my opinion, the Xtrainerz are another great product from Aftershokz. Comfortable headphones that stay in place and allow you to stay aware of your surroundings, what more could you ask for? Long battery life? Xtrainerz have that too as they’ll last for 8 hours without a charge and then fully recharge in just 2 hours. If you’re in the market for a new pair of headphones, consider a pair of Xtrainerz and use code “ BRBUNDLE” for $50 off the endurance bundle.
