Short answer: the SoundMAGIC E50C. It ranks #971 of 1369 in-ear headphones by sound quality, rated 3.2/5, at $32.99; the IvipQ IE-01 ranks #1048, rated 3.1/5, and costs $35, so there is little reason to consider the other one.
Why pick the SoundMAGIC E50C: Bass from 60 to 200 Hz sits within 0.3 dB of target, so the low end is balanced rather than boomy. Watch for: Presence from 3 to 6 kHz is about 6.7 dB under target, with an 8.7 dB dip near 3.3 kHz, so vocals lose clarity and sound set back.
Why pick the IvipQ IE-01: About 4 dB more bass than the Harman target below 150 Hz, for listeners who want a fuller low end. Watch for: An uneven response, 2.4 dB standard deviation from target.
Buy the SoundMAGIC E50C. It is rated higher for sound quality than the IvipQ IE-01 and costs less, which makes it the one to get unless you need something the other one does better.
