Short answer: the Hisenior Mega5EST Bass Plus, though neither ranks well in its class. Both are rated 2.8/5 for sound quality (#1055 and #1043 of 1291 in-ear headphones), and the Hisenior Mega5EST Bass Plus costs $589 against $599 for the Noble Audio XM-1, with sound quality a draw, the lower price decides it. Both are rated below 3.0/5 among the 1291 in-ear headphones, and the Truthear Nova, ranked #2 at $169.99, is a better place to start if sound quality matters.
Why pick the Hisenior Mega5EST Bass Plus: A limited-edition bass-boosted tribrid with about 3.9 dB of extra bass for listeners who want a heavy low end. Watch for: A Harman score of 59 and a warm tilt (-1.34), with treble about 2.2 dB below target, mean bass dominates and detail is softened.
What the Noble Audio XM-1 does well: Bass is lifted about 5.1 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: A 5.8 dB peak near 7.6 kHz can make cymbals and sibilance sound sharp.
Buy the Hisenior Mega5EST Bass Plus. Both are rated the same for sound quality, and it costs $10 less than the Noble Audio XM-1.
