good lord. Props to both you Sonic Electronix and NVX. these headphones are top notch. i was expecting mid grade sound out of the ES10's but i plugged these babies in and listened to RUN DMT - Curse of The Mummy (plug because it's an excellent bass song for systems) and when the bass finally hit, it gave me goosebumps. FROM HEADPHONES. these things are amazing. it wasn't too loud, or to harsh. but the smooth clarity of my music is honestly amazing. i haven't even plugged in the FiiO yet and i'm blown away.

These things handle the long, strong bass hits of dubstep, trance, and trap flawlessly. it handles the choppy aggressiveness of metal, and it makes rock and indie sound so much more dimensional (clarity of reverb, and balance of instruments). I even threw some Gustav Mahler (classical music) at them at it handles beautifully. these play the range of music beautifully, without any flaws.

That's not to say that all music sounds good on them :) poorly mastered and recorded music shines through as well. clipping and over compression sounds like nails on a chalkboard in these, which is a good thing! i mainly listen to metal, and dubstep, but i have everything from the 50's to Trap in my library. these headphones have made it so i can explore my library all over again :) THANK YOU!

For $*** dollars these are a steal, get loud than beats by Dr.Dre with less distortion! Crisp mids and highs, and the bass pounds, can't listen to very long due to west coast tweeters at very high levels atleast.

These are really great Earbuds. You can turn the volume all the way up (MAX) and it does not distort. The Sound is Amazing and You can actually hear everything that Your suppose to hear when listening to a good music. I'm really happy I got the NVX EX10S.

I really like listening to music on these headphones. They are way comfortable like that other guy said. They sound pretty close to some of the other earbuds that i have owned, but there is just something slightly different about the sound that i like better. I think it is a little more warm and rich then the others. They sound really nice. Very enjoyable.

The only drawback is that they give way too many ear tips and it took me a while to find the ones that fit perfect. The wrap around design is great and reduces the amount of noise that i used to get when the cable would rub against my shirt or other clothing.

Overall, i would buy these again.

of all the earbuds i have ever owned these are hands down the most comfortable. i wear them for several hours a day during work and i almost forget that i am wearing them. they sound greaet too. very happy with purchase.

Where do I begin with these? They have so many features for $100. The only feature they do not have that I wish they had is a mic + play/pause button. Here is my breakdown:
Sound:
I must say I never heard of NVX and was a bit worried about the sound quality before buying, but their over ear had some good reviews so I figured why not. I was incredibly impressed with the sound quality these have. They are so much better than my Klipsch S4i it's not even funny. The response is really balanced and sound staging is excellent. The bass also feels incredibly natural and not overbearing like some others and overall I am just really pleased. I have listened to alternative/rock (Counting Crows, Matchbox 20) and hip hop (Hopsin, Lecrae, Lupe Fiasco) and everything sounded the way it does on my studio monitors. I was left feeling like nothing was missing and that was really important to me in terms of whether I wanted to keep or return... These are keepers!
Cable:
Quite possibly this is the sturdiest cable I have ever had on earbuds, including much more expensive Shure and Westone. I contacted NVX to find out what they used and it is a pure silver cable. It never gets tangled, is durable as hell, and you can just tell the quality compared to standard plastic or even twisted/flat designs out there. On top of the toughness, it also looks great as it is silver.
Eartips:
The sheer number of eartips included is almost intimidating, but I got over it and got the exact pair that fit me. I really like how there are silicon tips and then also silicon with foam tips included. I went for medium silicon w/ foam and they are extremely comfortable. I also like the comfortmax flexible foam tips when I am traveling in public (airplane, bus, etc) as they offer a bit more noise isolation and I am even tempted to go buy a set of comply tips to compare.
Adjustable Nozzle Sound Port:
This is a really cool feature that is extremely undersold in my opinion. It is my favorite feature on these buds. Maybe it is because my ears are not normal or average, but because of the adjustable port I can fit these better than anything else I have previously owned.
Memory wire and earhooks:
The memory wire and earhooks are pretty cool and I have seen them on other sets, but the memory wire is softer than my Westone and more flexible. I am not a huge fan of the earhooks, but maybe for some people they will like those better. I left them in the box unused. For me, the memory wire works great at the gym or when I go running and really helps when it comes to plopping them out and then leaving them resting on my ears so I can talk with friends at the gym without having to have it hanging from my chest.
Cons:
I like complyfoam tips as I stated above so that would have been great to get those. I have an Android phone so I am not huge on the Apple 3 button mic thing, but either would have been better than not having that option at all. Even though I am fan of over the ear designs, I still find simple plug and play to be a little easier.
Overall:
I am pleased with the sound they produce and all the neat things that came with them.
