How did you find the vocals and mids of the IM50?
Nice to have more infos on this earphone!
Seems pretty consistent with what I read so far about the AX35. Especially the part where the mids is less forward.
PS: What does side grade means?
I agree, I don't think enough people has tried the AX-35's (or at least not comment on them). I use them with the small Sony hybrid tips and really like them. They're not exactly bass cannons but I still feel the have enough and I like a little hump in the lows. The clarity is very nice for the price.
Sidegrade means that one is not better than the other, they're just different.
May I know what earphone were you using before you tried the IM50?
The earphones I used before I auditioned the IM50 has very little bass. So when I tried IM50 for the first time, I found the bass overwhelming.
To have a more accurate listening of the IM50, I made sure not to listen with my earphones on the day I went for a second audition. As a result, the second audition went much better as the bass sounds more balanced with the other frequencies.
You can check out these threads for more opinions on the IM50:
I have the same opinion on the AX-30. They are clear, crisp and detailed, but bass is also not as weighty/deep/full sounding. I prefer more musical IEMs like Zero Audio Carbo Tenore and Philips Fidelio S2. Will give AX-30 a few more listens before deciding whether to sell them or not.
I have a pair of AX-35s and found the Radio Shack Auvio tips to give me the best bass boost and comfort of the tips that I have tried (Sony hybrids, stock, and Teac ZE-1000). YMMV. Cheers!
