Review: Perfect for cycling or running - Given some of the reviews I was a little skeptical of these but I have been quite pleased. Given that it's illegal in Florida (not to mention just plain stupid no matter where you live since it makes you oblivious to the world around you) to ride with earbuds in I wanted something I could use but didn't want to spend $100. So I tried these and have been very pleasantly surprised. I generally cycle in the 18-20 mph range so, yes, there is wind noise. And there is ambient noise. But that's the whole point - to leave your ear canal open so you're aware of your surroundings. Even with that, however, I've found I can hear the music quite clearly. Much better sound quality than I expected. I can hear all of my music just fine. Also, I live in an extremely high humidity environment so I sweat a lot and it hasn't bothered these at all. Can't really speak on how long the battery life is but I generally ride 5-6 hours with them and then charge them and it's always been fine on that schedule. They also fit just fine over my ears even with sunglasses and bike helmet. No issues on comfort there at all. Review: Bone conduction my ass - As the title states this is just an ordinary headphone with a twist on the design. It states that it send vibrations through your skull directly to your inner ear bypassing the ear canal. Well this conducts sound through bone just as well as a loud speaker on the other side of a wall that you stick your ear against. There is no fancy tech hear that makes this different. It is a regular speaker type headphone that transmits sound through a membrane just as an external speaker would. This is only different from regular buds as these are not placed into the ear canal. Nothing fancy here..... The way it is advertised to be used is to place the speakers just in front of the ear canal as they show in the pics. Do this and you will get terrible sound quality as this does not actually transmit vibrations as the marketers would lead you to believe. I find that this is best used when the speakers are placed directly over the ear canal. You get the best sound and the quality (when used in this manner) is actually quite good and you can hear the details of the music. However, at higher volumes, the sound leakage is very apparent and quite noticeable. If this actually did "conduct through bone" I would not be able to hear the sound when the unit is in front of my face. The only reason I am keeping these is that I feel these would work well in my job where I would use these for several hours in row and thus the comfort of not having something in your ear would be desirable. ## Features - Bone conduction technology uses vibrations to transmit sound waves directly to the cochlea - OpenFit assures unmatched ambient sound awareness and extended comfort - PremiumPitch patented dual suspension transducers guarantee the finest bone conduction audio - Nanotechnology treatment effectively repels sweat when used while working out - Be safe, be open - Sportz 3 provide an ear opening experience - Connectivity technology: wired ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JO9XTSI | | Additional Features | Lightweight | | Age Range Description | Adult | | Brand | Aftershokz | | Brand Name | Aftershokz | | Built-In Media | Cable, Protective Case | | Cable Features | Without Cable | | Color | Black | | Connectivity Technology | Wired | | Control Type | Media Control | | Customer Package Type | Standard Packaging | | Customer Reviews | 3.8 out of 5 stars 391 Reviews | | Ear Placement | Open Ear | | Earpiece Shape | open-ear | | Enclosure Material | Plastic | | Form Factor | open-ear | | Frequency Range | 20 Hz - 20,000 Hz | | Global Trade Identification Number | 00858510003161, 00858510003246 | | Headphone Folding Features | open-ear | | Headphones Ear Placement | Open Ear | | Is Autographed | No | | Item Weight | 1.6 ounces | | Manufacturer | Voxlink LLC | | Model Name | AS400 | | Model Number | AS400 | | Noise Control | None | | Number of Items | 1 | | Specific Uses For Product | Sports and Exercise | | Style Name | No Mic | | UPC | 858510003246 858510003161 | | Wireless Technology | Bluetooth | ## Product Details - **Brand:** Aftershokz - **Color:** Black - **Ear Placement:** Open Ear - **Form Factor:** open-ear - **Noise Control:** None ## Images ![Aftershokz AS400 Sportz 3 Open Ear Stereo Headphones, Black - Image 1](https://m.media-amazon.com/images/I/51LucXIVyEL.jpg) ![Aftershokz AS400 Sportz 3 Open Ear Stereo Headphones, Black - Image 2](https://m.media-amazon.com/images/I/51aPbJk2fFL.jpg) ![Aftershokz AS400 Sportz 3 Open Ear Stereo Headphones, Black - Image 3](https://m.media-amazon.com/images/I/51GiBeLNslL.jpg) ![Aftershokz AS400 Sportz 3 Open Ear Stereo Headphones, Black - Image 4](https://m.media-amazon.com/images/I/41rrQs0-ljL.jpg) ![Aftershokz AS400 Sportz 3 Open Ear Stereo Headphones, Black - Image 5](https://m.media-amazon.com/images/I/41HQwl01j4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for cycling or running *by C***Y on August 19, 2015* Given some of the reviews I was a little skeptical of these but I have been quite pleased.

I wanted the situational awareness of having uncovered ears while gaming and thought I'd give these a shot. It turns out, it's exactly what I wanted and I'll be buying a fancier set when I can't stand these anymore. The following comments are following an 8 hour stretch of initial usage. There's a couple problems with these for extended use during long fixed location gaming sessions. First of all, the wire is way too short. It's clearly intended for use mounted to a device in your hip pocket. The control box (and battery) is conveniently located for that use case, but is inconvenient and inappropriate for fixed-location use. I don't want to have to remember to charge the thing every night, so I wanted to see how it would work out if it was always plugged in to micro-usb power. First, I'd have to say... It works fine while plugged in (I didn't expect that). However, the control box is annoyingly awkward while plugged in. I attached it to my shirt, but it still had that extra wire hanging out the side pulling it in odd directions. I can't really count this against the device, since it did work this way and this clearly isn't the intended use case. If the control box could optionally be extended somehow, I could fix that to the desk and just have the one lightweight wire going up to my face. That'd be nice. The sound is a little odd. I wasn't sure what to expect. These aren't speakers filling your ear hole... and it sounds a little different. I don't think I'd want to use this to listen to music, but for games and Discord (voice chat) it was just fine. After a few hours, I hardly noticed the audio quality/tambre differences, but audiophiles would be annoyed. That said, people with very deep voices vibrated the crap out of my cheek bones. (I got used to that too. And I turned them down a little.) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/4809852-aftershokz-as400-sportz-3-open-ear-stereo-headphones-black](https://www.desertcart.tn/products/4809852-aftershokz-as400-sportz-3-open-ear-stereo-headphones-black) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-15*
