Excerpt: We’ve tested a lot of earbuds over the past few years and invariably find ourselves gravitating toward products at the very high end of that market—we’re talking buds that’ll set you back more than the most expensive iPod. At $200, Future Sonics’s Atrio m8 earbuds certainly aren’t cheap—but they’re competitive with some products that cost twice as much. The first thing you notice when you stick the m8s in your ears and hit play is the bass response.
Pros: Big bass that doesn't drown the mids and highs. Fantastic sound.
Conclusion: Without a doubt, the Future Sonics Atrios are my favorite in-ear monitors at the moment. No other IEMs I know of do so much right and so little wrong. They’re not the most "pedantic" phones out there, but they’re the most musical ones for my tastes. Almost like good full-sized headphones, they make the sound really enjoyable and they get my feet tapping no matter what style of music I’m listening to.
Pros: Great sound quality, clarity, and resolution across the whole frequency spectrum, Decent soundstage for an in-ear phone, Good audio quality even at low volume settings, Great isolation from outside noise, Very little microphonics and cable noise, Comfortable for a phone that goes quite deep into the ear canal
Cons: Somewhat difficult to insert and remove; sound quality depends a lot on getting a good seal in the ear canal, Sound signature might be too dark for some tastes – at least for people accustomed to very bright-sounding phones, No user-replaceable cable
