OSTRY KC06A Hi-Fi in-Ear High Performance Earphones Headphones

My second pair having lost the 1st. Probably the clearest and most sonically balanced ear buds I have heard to date. Sound is open with no sonic impedance by mfr compression or crossover issues. These buds shine in the mid frequencies (vocals) with very balanced bass and treble. Treble is very tasteful with no harsh sibilance. The low bass is present, however, may not be the earbud for users seeking bass heavy transducers. Good flat line, very clear, earbuds.Having issues getting warranty service for the existing buds I currently have that are less than a year old. Being manufactured in a different country with little presence in the US, it is difficult getting in contact with a representative from Ostry/Shenzhen for warranty matters. If after purchase support is important to you, then going with this mfr might not suit your needs. Sonically, they are worth the money. Hope this helps, excuse the brevity.

In terms of sound quality, these are among the best earphones I have ever owned. However, less than 4 months into owning them, the metal grill covering one of the sound holes came loose and dropped out, exposing the innards of the earphone. The rest of the earphone's build quality is fine, but I expect my products not to fall apart before at least a year of use.

Soundstage: The first thing immediately obvious to me upon using these earbuds was what soundstage actually is. I've heard this word thrown around before. Frequently when talking about the KC06As. The sheer "wideness" of the sound these put out is amazing, compared to my previous sets of earbuds (Thinksound ts02, Brainwavz S1). Actually got my jaw to drop upon using them the first time.Warmth: These really are warm sounding earbuds. Strings, vocals, midrange are all emphasized and focused on. These earbuds accomplish this very well, but this better be what you want from them. My Brainwavz seem a lot flatter in comparison.Comfort: Easily the most comfortable of the earbuds I've tried. This is a very important one to me, as I use earbuds exclusively for comfort reasons. Haven't found any Over-Ears or On-Ears that I can comfortably wear for 8+ hours. These feel very light in the ear, although they certainly aren't in the hand (full metal casing). I think it's from being flatter and keeping the cord close to the head. The shirt clip helps a lot here as it takes the weight of the cord off of the earbuds.I really like the sound these put off. I feel comfortable turning the equalizers off on my devices (previously tended to have the EQ a bit bass focused). They're warm and punchy, and if you buy them you really ought to be seeking those attributes out. You can make them pretty damn bassy if you want (three of the tip pairs seem to be intended for this).Onto the physical stuff: Surprisingly good. These are obviously Chinese. The website is in almost-Engrish, and so are the manuals. Lots of Chinese writing on the packaging. The kickass sound and shockingly solid construction (metal casings, metal plug grip, metal Y splitter) make that inconsequential. My set came with 7 pairs of silicone tips (one pair with mesh filters), a shirt clip, ear hangars, and a carrying pouch.If these were priced at $120, I wouldn't bat an eye. Pleasantly surprised they aren't.End of 2015 edit:So I actually wear these so much it makes my ears bleed. Literally. I think it's because the housing is metal and somewhat sharp, but I have these in so frequently that I have to stop myself from wearing them for a few days or I get abrasions in my outer ear canals that bleed.So yeah, while they're comfortable for wearing for 8 hours at a time... doing so for weeks might not be sustainable. For casual use, these are pretty much flawless. As a lifestyle choice I'm not so sure anymore.

These IEMs sounded great. I really enjoyed using them, and wish they would have lasted longer. They didn't come with an in-line mic or controller, but still would have been a 4 or 5 star product. Unfortunately, they didn't seem to be well made. The left ear just went dead. There were no drops, smacks, or other damaging factors. It started off minor, like not working once then, after literally touching it, working fully again. Then slowly but surely the problem got worse and worse until it flat out didn't work any longer. The headphones would have been a great buy, but because of the seemingly low build quality, they were not.

I bought my first pair of these KC06A earbuds from Massdrop because I got a good deal there. Didn't have any idea how they would sound but reviews were good. These are by far the best earbuds I have ever owned. I have taken them to France and Spain and worn them around my neck to use in place of the cheap earbuds they provide on tours. I've drop them and actually stepped on them, ground them into the concrete, and they still work great. I use them every day here on the ranch for music, talk radio, whatever. They are rugged and the cords do not tangle. The cords have a surface that makes them just fall apart and untangle pretty much on their own.If you get these pay special attention to which foam tips you use. The different tips aren't just for different size ears. Each set of tips produces a different type of sound. I prefer bass so I use the tips with the biggest hole. Don't recall the item number but you will see they are the biggest in the selection that comes with the earbuds. They have a nice little drawstring bag for carrying in your pocket.I like these so much I bought everyone in my family a set for Christmas last year. They all love them, too. They are very well made and I have three pair because I keep misplacing them. Every time I'd lose my earbuds I would buy another pair. They are part of my day. Eventually the lost ones always show up so I have three. I can always find one of the three. My wife also has a pair that she uses. I always make sure to take them on the plane, too, for watching movies or listening to music. I haven't listened to every set of earbuds out there but of the ones I've heard, these are the best.
