I have the Aeropex model, and will soon be ordering the OpenRun Pro's. If you're a fitness fanatic then look at other reviews. I service equipment in the field, which means I may be in the middle of a diesel engine repair shop, warehouse, or someone's home. I used to carry earbuds, but my ears no longer tolerate them. Earbuds block most external sound. You can't hear that fork lift that's about to put a fork through your spine because he's watching the pallet, not his forks. WIth Bone Conduction you can hear in 360 degrees, and relay from your phone contact to an in-person contact flawlessly, without worrying about the nearby person over-hearing the incoming speech. It's the ultimate in security and safety! I used to like my over-ear headphones but the over the head support messes up my hair, or worse, traps it and pulls it out upon removal. No such problem with the behind the back of the head design. The sound control is excellent, it's easy to turn down the sound from the unit, to better hear your environment, WITHOUT losing comprehension of the phone conversation. It's like a one-way speakerphone. Your phone contact can hear someone close to you, but you have to relay the conversation from the phone contact to the person nearby. Great security and you can translate at will, especially helpful when the other end of the phone call isn't a native language speaker. They also coexist perfectly with eyewear. I haven't had any eye-protection or glasses that don't work well with these units. Flaws: Some music or voices will cause a 'tickling' sensation. Depending on the thickness of your skin/subdermal lipid layer, this may be problematic during long hold-times with a male voice-over. For the price, I would appreciate a case that also serves as a battery backup/charger. The included magnetic USB cable is great, but when you're traveling it's not exactly convenient to turn off then plug in your connection to the world. I would prefer to be able to charge while using the unit. My Aeropex shut down when connected to the charging cable. Comfort: for me the Aeropex is very comfortable. It's only troublesome when you're wearing a hoodie, as the rear support piece can catch on higher collar shirts/coats/jackets/jumpers. We're required to wear collared shirts, as white-glove field engineers.

The sound/ volume is very low and the material looks weak and flimsy. I like my older ones better. Those were sturdier and the the sound/volume was a little louder. Since they don't make these as before I think I'll try another brand another time. That's too bad because I loved this brand.

I have wireless beats. Those have better sound, but these are great. Super user friendly and let's be honest if you're buying these it's not for the best sou d ever but because they are open ear. They're great, have really good sound and volume. I totally recommend them.

The unit is acceptable when I am either running, or lifting weights. But when I’m cycling, even when I turn the volume all the way up, the wind noise from my ears, diminishes the sound I hear. At times, I can barely hear the lyrics of the music. my average speed on my bike is around 17 to 20 mph. I’m sure for some people that are cycling at a lower speed, this wouldn’t be a problem. But it is for me. Very disappointed. I’m going to have to find some other earbuds for cycling that provides a better environment for listening.

Headphones are extremely comfortable, but sound quality and loudness was underwhelming. Walking through a busy warehouse was too much to hear anything with these, even with the volume all the way up. Once the volume was all the way up, distortion began. For the price, these lack the sound quality I expected. If you are looking for extreme comfort and will mainly listen in low-noise environments, then these headphones will do you good.

This is my second set first one had the Mike best I’ve ever had. It quit working at two years. Upgraded to open pro ! Total junk, driving down the road where my other headset always worked and people could hear me and nobody can hear me and I cannot hear anybody as your sound is not as good as the other side I would not recommend this to anyone

I tried a pair of the Trekz Air that my sister had before buying these. The OpenRun Pro feel better in pretty much every way and I'm totally in love. I've yet to be in a position where I've need to worry about a charge despite using them pretty constantly throughout my work day.

This is my second pair of bone conductive. The ability of how this pair connects so much faster. And feels lots more comfortable. The new way of charging is so easy and charges so much quicker. My first pair wa the cheaper pair. I liked them. Had 3 or 4 years. I broke them. So this time I upgraded in purchasing the top set. The comfort of this pair is top knotch.

This is my third pair that I purchased. First of this style in the product line offered. The handling keeping the vibration down is improved. I always like the feature of nothing in your ear canal to hear what is playing off of your device. This is a big reason I have turned to using your product. I have skin irritation around and in my ears, this solves that issue while still being able to listen to a device. Only draw back is when I looked into downloading your app so I could change the equalizer with my smart phone, it seemed to have a lot of third party conditions looking into my daily internet activity. Lots of tracking for information not having to do with my phone or OpenRun Pro device. So I didn't get the app. I still would like to download and control those extra features, but just without the third party tracking attached. Since I can't tweak and use this fully yet, I can only say that so far I'm okay with the sound quality. I have no idea if it can be better. But out of the box is fine, the vibrations are tickling less and hardly an issue.

I run at night and on a road that is moderately high traffic (not as much when I run) and the speed limit is 55 mph, so I need to hear these cars coming. These work great for that and I can still hear my music great. They are very comfortable and easy to use. I haven't tested the battery life yet, but have been great on my shorter runs (longest I've gone so far is just 3.5 miles) and there was still quite a bit of charge left. There isn't a way that I ve noticed to see how much charge is left though. The voice when you turn it on just give a generic "high", "low", etc.
