Short answer: the Final Audio E4000, though neither ranks well in its class. It ranks #1131 of 1291 in-ear headphones by sound quality, rated 2.2/5, at $162. The 1MORE Penta Driver ranks #1136, rated 2.1/5, at $139.99, $22.01 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 1291 in-ear headphones; for better sound, the Truthear Nova ranks #2 at $169.99.
What the Final Audio E4000 does well: Lower mids sit within about 0.6 dB of target, keeping voices and guitars natural. The catch: Presence sits about 5.9 dB low with a 9.8 dB dip near 11.5 kHz, so vocals and instruments lose some bite.
Why pick the 1MORE Penta Driver: Bass sits about 1 dB above target between 60 and 200 Hz while the treble is pulled well back, so listeners who like a warm, dark presentation will find little that sounds sharp. Watch for: A deep 13.5 dB dip at 6.6 kHz and a presence band nearly 8 dB below target leave vocals recessed and cymbals dull, which drags the preference score in HypetheSonics’ measurement down to 51.
Buy the Final Audio E4000. It is rated higher for sound quality, and the $22.01 you would save on the 1MORE Penta Driver does not close the gap.
