Short answer: the 1MORE Penta Driver, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#1136 and #1138 of 1291 in-ear headphones), and the 1MORE Penta Driver costs $139.99 against $170.95 for the Sennheiser CX Plus True Wireless, and with sound quality even, the cheaper one is the better buy. 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 1MORE Penta Driver does well: 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.
What the Sennheiser CX Plus True Wireless does well: Supports aptX and aptX Adaptive along with AAC and SBC, so it streams well from Qualcomm based Android phones. The catch: An 11.4 dB treble peak near 10.2 kHz makes cymbals and sibilance sharp and fatiguing, while a 6.6 dB shortfall from 3 to 6 kHz hollows out vocals.
Buy the 1MORE Penta Driver. Both are rated the same for sound quality, and it costs $30.96 less than the Sennheiser CX Plus True Wireless.
