Great sound!
Used for audiobooks as well as music. Works well without disturbing others. Used in a hospital setting.

Fantastic!!
For someone who has struggled finding ear buds that fit them well, I wanted to try ones that wrapped around my ear more for a better fit, and ooh boy these did not disappoint. They have the same if not better sound quality and volume as ear buds that sit in your ear. The battery has always lasted me the desired time. (Although I don't use them for extended amounts of time, just a few hours here and there.) The functions are easy to use while wearing them. Overall, these ear buds are a great quality for a relatively low price and are extremely comfortable to wear. :)

Fit it's great but volume needs helps
When I put these on, they are everything I always wanted but never thought was possible from an ear bud. They are so light I forget they are in most of the time. At the same time they feel very secure and have never fallen off. Here's where the bad news comes in. The only volume these things produce is comfortable, loud and louder. I really wish they went just a little more quiet. I still use them all the time but I can't suggest them to anyone because of the volume issue. UPDATE: I came back to re review these headphones as I don't think I was fair. After getting a new phone these are now perfect and I'm able to hear comfortably. I think it my phone didn't have ever difference between the lowest setting and the next higher up. Changing my score from a 3 to 4.

Ease of operation and sound
Easy to pair with iPhone and sounds is great. . . .

Absolutely love them!.. when they work
These are so incredibly comfortable! I love not worring about my earbud falling out of my ear, and I love the open ear concept as well. Phone call quality seems to be very good, I've had no issues with people being able to hear me. The ear buds do not hold an 8 hour charge. I usually have one earbud on, then when that gets to 10% (you can NOT ignore the low battery alerts!), I switch it for the other one. In an 8 hour shift, if I am listening to something nonstop, I have to switch earbuds twice. When I am wearing both earbuds, it is very common for the sound to cut out in one bud then come back randomly, creating an inconsistent sound quality. One of my earbuds will not lay flat in the case, so I have to close the case for it to turn it off or charge it, which isn't that big of a deal, but I have no issues with the other one. Even with the inconsistencies, I would buy these again.

So many problems after a few months of moderate use.
This would have originally been a 5 star review, but these headphones have barely lasted 6 months. The first problem to appear was inconsistent charging; I brushed the contacts clean but that doesn't change the fact that sometimes the earbuds just don't charge and sometimes they start charging and then stop well before they are fully charged. The next problem arose when the earbuds started dropping the bluetooth connection. One moment you'd be listening to something and the next moment it would be silence. Only putting the earbuds on the charger (if it recognized the charge) and then taking them back off to reconnect to the computer would restore the connection. The latest problem is a drop in audio quality. What was the earbuds strong point is now too poor to listen to, with crackling at medium-high volumes. This is independent of the source of the audio, it's coming from some sort of speaker degradation of the sound with the earbud. I don't know if this model is just this bad in general or if I got one that somehow squeaked past quality control, but these earbuds are now unbearable and it's barely been more than 6 months.

Best open ear headphones I have ever owned
I absolutely love these headphones! I do a lot of running, especially on trails where it’s important that I hear my surroundings. These are light, sound good, and stay in place.

Not so great Monster ear phones
So I purchased these with high hopes of comfort and sound quality. Well its hard to give it a better review. At first they felt comfortable around my ear. But with long time wearing i began to get ear fatigue. Not as bad as Ipods. The sound quality for these is ok at best. The low frequencies (bass) would vibrate the headphones. So cant listen to upper volumes. When i got them out of the box. I placed them onto the charger. Wanted them to be at 100%. At first they would hold charge for 6-7 hrs but now they dont even hold 4hrs charge. No way you can get a full days worth of use. Even worse for all day travel. Not sure if they get better with different models from Monster. For the price I did expect a little bit more from them. I travel a lot. So i will continue to look for better phones. I tried to send them back but navigating the Monster Website is a fail for support. I tried sending an email but no response.

I have tiny ear holes and all the ear buds regardless if size, hurt. These are perfection! They don't hurt at all as they don't go inside the ear. The Clio around the ear and sit in front of the ear hole. The sound is great and doesn't feel like it's too loud for my ear drums. Best over the ear buds I've ever used!

Basic set up, and super easy to use. Price is was amazing. Comfortable to wear and secure. Good sound while still being aware of your surroundings.

They seem comfortable and with a good sound quality, the only gripe I have is I got them white and the color is closer to a pale pink rather than white.

Exactly what I needed. Sound quality is good but you won't get the mega bass like with closed-ear or insert style buds but I didn't expect that. The tradeoff is there are no worries about the buds getting sweaty and falling out. No worries about people sneaking up surprising me when I'm working out, I can watch TV with these on at low enough volume, say when watching the news. Don't have to pull then off when I want to hear something. These are great.
