First time poster here so hello everyone!
I bought these M5s as my first decent IEM after reading many positive reviews, but so far I'm definitely not happy with my decision. Sound lacks bass, is too airy and thin. Basicly they sound worse than Apple stock earbuds (old model). I'm quite certain that, since the reviews are so positive, my pair is either broken or I cannot get a good seal.
The sound I'm hearing is not distorded in any way and I can hear the bass frequencies, but they just are really recessed, so that leads me to believe that they're probably not broken. I tried all the tips to get a good seal, but nothing seems to help. I borrowed my friends cx-300 II to compare and with those it's really easy to get a good seal. I just plug them in my ears and get the same feeling as having earplugs on. For some reason this doesn't happen with the M5s. I even tried the cx-300 tips, but they were only slightly better (could be because cx-300s nozzle is slightly bigger so they don't maybe fit M5s properly).
Any ideas what to try? I could order some other tips if you believe it really is just a seal problem or do you think they just could be defective? I've listened to the Sensaphonics seal test (http://www.sensaphonics.com/?page_id=833) and 500Hz is definitely way louder that 50Hz, so it could indicate seal problem.
I've opened a ticket about returning these, but since I have to pay return postage, I'd rather keep these if I can them working.
For reference, in home I'm using Lavry DA10 with HD 650 or Genelec 8040 studio monitors so I'm fairly used to "good" sound.
Any help would be appreciated!
Problem sorted. Today I got some cx-400 tips and the bi-flange tips did the trick. I won't go into detail but the sound is now good and would definitely recommend these for the price.
It actually seems that when changing tips I didn't push them far enough into the nozzle. The tips kind of naturally lock to the wedge on the nozzle and since I'm not too familiar with iems, I thought that's the spot, but it seems that the tips need to be pushed all the way.
What's confusing, is that now the tip goes over the small vent where the nozzle meets the body and what's the point of the vent if it gets or almost gets covered?
