Like the awareness you have with these headphones. I had the titanium model from about 4 years ago. These are a significant update as they have multi point Bluetooth. Sound is richer than the titanium. Voice calls are much improved. I have yet to try them on my bike the ultimate test. I recommend them to cyclists and runners. Regular in ear headphones are just too dangerous.

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.

Open design allows you to hear the surrounding environment, which allows me to wear it during work. I can listen to podcasts and still be able to hear my colleagues. The best part comes with bone conduction. I had been slowly losing hearing (no eardrum) until I lost it completely after surgery (hopefully only temporarily) when they had removed those three important bones in the ear. With these headphones, I still can enjoy music and podcasts!

I really hoped these would be the answer to my listening needs! They arrived and sound quality is great but they just don’t fit my head (bought the mini). The ear parts are just not the right size and they slide down making it impossible to hear. The shape of the curve is too deep for the anatomy of my ears. I’ve been trying to reach customer service for 2 weeks and have been unable to get through due to high volume calls or maintaining on the line which is frustrating.

Main problem is that I can barely hear the voice of the narrator of the Audible book I'm listening to when I walk outside. It's better indoors in a silent room but I never listen that way. It's just not loud enough. Also, when I press the "on" button, I don't really see the indicator light up to show that it's on. It's much clearer on the "off" button.

I really like these! I have very small ear canals and the in the ear earphones are quiet painful. The only thing I would like is for these to be a little bit louder for those times when there is a lot of background noise. Other than that I am very happy!

These are the Open Run Pro, to be clear. Sound quality is awesome. However, this is not at all what I would consider to be 'bone conduction'. These have 4 speakers on them, 2 on each side. They make no contact whatsoever to bone. The speakers are on the piece that is in front of the ears. Again, great sound but that is NOT bone conduction. That is purely speakers. If I cover those with my finger, sound us muffled. Fit is good, sound is good, quality is good, just not what it said to be, says bone conduction and that's what I expected, if I wanted speakers I could have bought speakers. Disappointed for sure!

These headphones are so comfortable to wear, even for long periods of time. The sound is clear. Concern about losing an earbud is eliminated with this style of headphone. The controls are simple so adjusting the volume or turning the headset on/off is ALWAYS easy and not distracting. Being able to hear surrounding background sounds makes these the safest choice around.

I bought this mainly for work meetings, not for listening to music. I like it except I'm still figuring out the best way to wear it with my glasses. Sometimes it feels like it's hurting the top of my ears where it loops over but I think if I align it to sit side-by-side with my glasses instead of on top of each other, it feels better. There are days when I feel like they are too tight and gives me a headache. Bottom line, I'm still testing these out.

Great headset. They start to distort after a few hours of the high volume. I like my music louder so I guess they weren’t designed for the max volume all of the time. Great to wear while running and cycling. Can’t even tell that they are on my head after a fem minutes of wearing them.
