Thanks for all the input guys. The K3 is way over my budget, and the M4 does looks intersting. I'm not really looking for a great sounding IEM (I doubt I would be doing any analytical listening outside), just decent relaxing sounds with great build quality. The B100 does have some nice input on sounds, but the upper cable from the Y split does makes me question the longevity of them. My dealer nearby does have some Vsonic IEM in stock so I will go check it out. Then there's the Radius stuff too, though their cheap offering aren't exactly cheap either compared to the chinese one.
If longevity is something you are looking for, i suggest you stay away from Vsonic's. I had 4 vsonic iem's, 07BE, VSD5, AN16 & Vsd2. All except the vsd2 started failing near the cable strain relief area(either iem side or jack side). And honestly, i take real good care of my iem, always keep them in a pouch, never take them out of my house too.
Off the top, the iem that comes to my mind for relaxed listening are the carbo tenores. Really great and they cost just about 35 bucks. However, again you need to take good care of them as the cable feels too fragile. That said, ive had a pair for more than a year now and they are still going strong.
P.S: Vsonic's sound great. The Gr07BE is a masterpiece to this date and the VSD5 isn't far behind. However, they are not for relaxed listening as they are quite extended and HOT in the treble region.
