NVX Audio In-Ear Monitors [Earbuds] High-Fidelity w/ PivoTip Patented Technology, 15 Pairs of Tips including ComfortMax, Tangle-Free Silver Wire, Memory Wire and Ear Hooks [EX10S]

I'm what you might call an audio fiend. I have several nice pairs of cans including some Sennheiser HD-600s. However, I've never been really excited about spending over $100 on a pair of earbuds. These were on sale for $70. I liked them so much I bought another pair.The good:- The ability to differentiate instruments spatially with these buds is phenomenal. I listen to a lot of EDM and on a lot of earbuds the different percussive layers all get intermixed...here every sample and instrument is a lot more distinct and clear. Better clarity than my full size HD-280 Sennheisers that retail for $100.- The frequency response is very flat. I actually enjoy a little more bass and a little less high then what these buds give. However, with the app Accundio on my iPod I'm able to create really awesome custom EQ presets to fine tune the buds to my liking.The Bad:- Don't have any serious complaints. However, I will say I am still trying to find the most comfortable tips to put on. The ones that are the best sounding are not completely comfortable to wear for long periods of time. Kinda ironic since so many tip options exist here that I find these less comfortable then my Sennheiser earbuds. Oh well, can't have everything.Overall I am very happy though. These seem to have been designed for and by people who really care about the details. I would say 'would buy again' but I already have :)

An overall good pair of earphones, acceptable sound (hit all frequency ranges) & bass. They are adjustable once in your ear, the outer skeleton upon which the wires reside wrap around your ears creating strong stability (i.e. little to no movement once set), and most important is that feel like a natural extension of yourself. To be frank sometimes I just leave them on/in because they don't hurt at any point during the day, or I just don't notice sometimes I left them in.The reason for the four stars is that the cable after 8-months of use has become internally damaged, and I expect a year out of my earphones always. I am disappointed by that but I would them to anyone for it qualities; they are good buy.Beware of abusing them though if you want them to left you longer than eight months

I'm by no means an audiophile or audio expert but I am an experienced audio junky. I've owned dozens of IEM's over the years from cheap(skullcandy) to expensive (Klipsch X10's) so I do know a thing or two about IEM's and sound quality. These are very nice mid range IEM's. They are nicely balanced and with realistic bass. I listen to pretty much anything from Fleetwood Mac to Tech Nine and these guys perform admirably. Be realistic and don't expect a mind blowing life altering listening experience bit you can expect a very nice balanced one. As far as comfort goes they are some of the most comfortable I've ever worn bar none. Right up there with my Klipsch X10's which speaks volumes. I would most definitely purchase again.

With these IEMs it's pretty hard to find a good pair of tips, so it's a good thing that they include a whole lot! The only two that work well for me are the ComfortMax and double flange tips. All the rest initially provided a good seal but would quickly slip. The material they used for the tips don't grip the ear canal well. When I wear the ComfortMax tips, I definitely feel comforted; however, the bass and lower mids become a little too bloated for me which reduces the soundstage and image separation. This is good if you like an intimate and warmer sound. I like wearing those for bassier tracks. I like wearing the double flanged tips most of the time though. With these, it is incredible how detailed and open these can sound, comparable to my HD 598s. The music is centered in your head, however there is an impressive ammount of depth and width in the soundstage. With these tips, the sound is brighter and there is a loss of punch to the bass; I prefer this though. With all of the tips provided, there isn't much isolation, especially for an IEM. If you want isolation I'd suggest buying Comply tips, but be aware that the bass gets another elevation with those. The earphones then sound really bassy and the midst and treble get put into the background. So with different tips, you can mess around with the type of sound you want, but you will give up something at the same time.
