On the other hand, the CX 80U features a frequency response from 17 Hz to 20 kHz, achieving a maximum SPL of 119 dB SPL and also a THD under 0.5%.
Microphone and Pricing Details
Both models come equipped with an in-line MEMS microphone for calls, featuring a frequency response that spans from 100 Hz to 10 kHz, and offers a 24-bit, 48 kHz output.
The suggested retail price (MSRP) for the CX 80U is $39.95, while the HD 400U is priced at $99.95. Consumers can find both headphones available from authorized dealers and on sennheiser-hearing.com as of now. Shoppers can also explore the Sennheiser store on Amazon for these products.
