    • Rompen expectativas
Unos audífonos por el momento super buenos, tienen un alto volumen. Muy recomendados, pero no son perfectos y mis opiniones para mejora serían: 1. Aveces se entrecorta la señal aunque tenga el celular en posesión 2. El color es muy elegante pero se mancha muy feo, sería espectacular un color negro. 3. Que tengan una app para poder configurar los comandos jeje. Pero muy buenos la verdad ... show more

    • Loving my new Earbuds
Great quality loud sound very comfortable. I always had trouble with the ones that sit in your ear. These just sit right outside your ear and feel sometimes I forget they’re there.

    • 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. ... show more

    • Great sound quality and comfortable to wear
These sound really good. I can't stand the feeling of earbuds that go inside your ears and sometimes my regular headphones get too hot or slip off if I'm too active. Ive used these to meditate, while walking and while cleaning and so far they've stayed put everytime. Just fyi, because they don't go into the ear you will hear outside noises but I don't mind this. The only reason I didn't give 5 stars is because any time I accidentally touch them or try to readjust, they shut off. This is because you can tap them to shut them off, but this feature isn't really necessary since they automatically shut of when you put them in the charging case. You're supposed to be able to tap them on also, but that doesn't always work so I usually just put them back in the case for a few seconds then pull them back out (they turn on automatically when removed from the case). ... show more

    • Best pair I've had
I like them, they're comfortable and I don't worry about them constantly falling out.

    • These are great
Great sound quality and battery life. Only issue is we have two sets and they cross connect when the girls try to connect at different times and they are in close proximity.

    • 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. ... show more

    • Yes for music no for phone calls
The sound is great , and they are very light and comfortable. The only one thing I’d say I don’t care for how others can’t hear me well when on the phone . So if your using for music I’d say yes but for phone calls I’d seek maybe something else.
