XK Audio X1266
The XK Audio X1266 is a wired over-ear headphone that draws clear inspiration from a well-known high-end design, aiming to deliver a similar aesthetic and sonic character at a more accessible price. It features dual 70mm dynamic drivers and a robust build, though its high impedance and moderate sensitivity suggest it will need a capable amplifier to perform at its best.

- Pro:Solid, substantial build quality that feels premium
- Pro:Wired connection with a standard 3.5mm jack for easy compatibility
- Con:High impedance (280 ohms) requires a powerful amplifier
- Con:Moderate sensitivity (97 dB/mW) may not be ideal for portable use
- Con:Heavy weight (400g) could cause fatigue during long listening sessions
