Hi,
I understand the criteria used to rate the best earbuds - what I don't understand is how anyone can listen to Hisoundaudio's paa-1 pro's and possibly compare them to Yuin pk 2 or 3 for that matter.
For the price point there is nothing that I have tried that delivers more sound than the Yuin pk series. I am a long time musician with experience in the studio and on the stage (about 40 years). The Yuins are more up front and the sounds are well defined. They might not have a kick ass, bombastic bass, but they're pretty good from the bottom to the top. I own pk1, 2 and 3s.
After reading your ratings I went out and bought a pair of HS paa-1 pro's . . . . . . huge waste of money, time and effort! Let's not get into the 100 or so hours of burn time needed to assess these buds - 100 years of burn time wouldn't change the fact that they are not a high quality bud.
Please, people don't be mislead into thinking these are quality earbuds -THEY AREN'T! It's possible that HS Live or Living are much better, but I'll stick to the tried and true Yuins I have and be thankful that I haven't wasted any more money. As a matter of fact - If you pay the postage I'll send you the Pro's I have for free!. . . . I just want to forget I ever wasted my money on them.
