The CMF Headphone Pro from Nothing is a budget-friendly over-ear wireless headphone that punches well above its price point, offering a robust feature set including hybrid ANC, LDAC support, multipoint Bluetooth, and an impressive 100-hour battery life with ANC off. Its sound is lively and well-tuned for the price, while the build and controls feel solid for the cost, though some compromises exist in water resistance and EQ customization.

Sennheiser HD 424
This vintage open-back Sennheiser stands out among its era peers, offering a notably wider and more immersive soundstage with improved low-end detail. However, its extremely high impedance demands substantial power, making it best suited for dedicated headphone amplifiers rather than portable devices, though it can manage at lower volumes on weaker sources. It's a compelling choice for those seeking a classic, spacious sound signature and willing to invest in proper amplification.
- Pro:Spacious, open soundstage
- Pro:Better deep-bass resolution than earlier models
- Pro:Lightweight at 180g
- Con:Very high impedance (2000 ohms) needs powerful amp for loud listening
- Con:No noise isolation due to open-back design
- Con:Hard to drive from portable gear at higher volumes
