I'm, using an A4tech mk510 dual earphone right now. The sound/cost ratio is phenomenal. Better than higher end sony earphones. The other side ( with sound isolation) is good if you're in a noisy surrounding and what to more bass. My personal favorite is the other side which gives a whole sound, the detail really amazes me. Bought it for just P375 i think and I get complements with the earphone with the look and sound. Been using it to check on out recording recording.
i totally agree. it's what i'm using myself right now. this baby, i bought for Php 450.
i wanted to buy these (since i've already had two pairs of these before, but due to abuse, both needed to be replaced) then i saw the dual a4tech.
not the most convenient earphones in the world, especially for long-haired people like me. it gets in the way of the hair most of the time, especially if you're the type who puts the wiring underneath your top. then again, sound-wise, you couldn't get anything better than this (at least for it's price class)
i like it dual. sound isolation, you use one end. if your ear starts hurting and gets tired of the in-ear end, you turn the other side and use the normal end. (i forgot the term though). it's got sleeves for the in-ear, and foam pads for the other end.
pretty happy with it. well worth your buck.
