Short answer: the SoundMAGIC E11, though neither ranks well in its class. Both are rated 2.5/5 for sound quality (#1095 and #1093 of 1291 in-ear headphones), and the SoundMAGIC E11 costs $42.99 against $54.99 for the Anker Soundcore Space A40, with sound quality a draw, the lower price decides it. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the Intuaura Reference 2019 instead, ranked #7 at $34.99.
The case for the Anker Soundcore Space A40: Active noise cancelling, LDAC streaming, IPX4 splash resistance and a claimed 10 hours per charge (50 with the case) make this a well equipped set of true wireless earbuds for the money. Watch for: Sub-bass falls 6 dB below target by 42 Hz and is 7.5 dB down at 30 Hz, so deep synth bass and movie rumble go missing.
The case for the SoundMAGIC E11: A low cost wired in-ear with a 10 mm dynamic driver. Watch for: A preference score of 55 in crinacle’s measurement shows a tuning well off what most listeners prefer.
Buy the SoundMAGIC E11. Both are rated the same for sound quality, and it costs $12 less than the Anker Soundcore Space A40.
