Subjective experience, day 1:
Not counting the el cheapo local brands, Walmart in my area had only Philips and Sony. Of the styles and types available, I liked, and bought, two from Philips: a 45 yuan pair of buds and a 100 yuan pair of canal phones.
The buds are large and (in one ear) uncomfortable, and lack something in the sound. It's not a lack of bass. There's muffled thrums and thumps a-plenty. These buds are in fact louder than the pair I was used to. What they lack is brightness of sound. I can't think of a better word. It's not lack of treble, nor of bass. It's sparkle. Brightness. The sound is hollow.
By contrast, the canal phones are okay. The sound is closer to what I expect. It lacks a little, and an audiophile wouldn't accept it, but it's okay, I guess. The difficulty is I can hear every step I make and every breath I take. This afternoon I went out to do a Chinese lesson and took an apple with me. The sounds of my own eating blocked out the mp3 sounds. Plus, it freaks me out a little to hear the music sound so clear and normal and to not hear very much at all of the surrounds.
So, 145 yuan down and cheapo is not the way to go. Unfortunately I don't know where to buy better other than online, and I discovered taobao has the replacement sets of the headphones that come with my phone. (For 25 dollars each.)
Where do you guys buy yours?
