Short answer: the Whizzer HE01. It ranks #361 of 450 in-ear headphones by sound quality, rated 3.4/5, at $45. The SoundMAGIC E50C ranks #376, rated 3.2/5, at $32.99, $12.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Whizzer HE01 does well: Bass, low mids and upper mids sit within about 1 dB of target, giving a warm, full-bodied sound that suits warm and bassy listeners. The catch: Hobbyist measurements on squig.link show an 8 dB dip near 6.4 kHz and treble about 4 dB under target, which dulls cymbals and detail, and sub-bass falls about 3 dB short.
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. The tradeoff: 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.
Buy the Whizzer HE01. It is rated higher for sound quality, and saving $12.01 with the SoundMAGIC E50C does not make up for the sound-quality gap.

The Two Headphones In Full
Whizzer HE01: $45.00 Amazon eBay
Pros: Bass, low mids and upper mids sit within about 1 dB of target, giving a warm, full-bodied sound that suits warm and bassy listeners. A preference score of 66 is respectable for an inexpensive single dynamic driver. At 18 ohms and 112 dB/mW it plays loud from any phone.
Cons: Hobbyist measurements on squig.link show an 8 dB dip near 6.4 kHz and treble about 4 dB under target, which dulls cymbals and detail, and sub-bass falls about 3 dB short. The CCA C10 and KZ ZS10 Pro both carry higher ratings for slightly less money.

SoundMAGIC E50C: $32.99 Amazon eBay
Pros: Bass from 60 to 200 Hz sits within 0.3 dB of target, so the low end is balanced rather than boomy. The inline microphone makes it usable for calls, and the 51 ohm impedance with 102 dB/mW sensitivity works with most phones. It is a very low-cost way into a warm tuning, with a preference score of 64.
Cons: 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. Sub-bass is 2.8 dB low and the top octave is about 3.8 dB down, which limits both rumble and air. The Whizzer HE01 has a higher rating.
