TinHifi P1 Max

The reviewer finds the Tin HiFi P1 Max to be a competent planar IEM with a warm, laid-back V-shaped sound, good technicalities like treble extension and layering, but notes weak bass attack and a need for well-recorded music. It's compared favorably against other 14mm planars, though fit security is a minor issue.

The reviewer finds the Tin HiFi P1 Max to be a well-tuned but average-sounding planar IEM, with a warm, relaxed, and safe signature that stands out mainly for its tame treble and upper mids. It improves on the P1 and P1 Plus but is outclassed in technical performance and detail by competitors like the S12 and Timeless, making it a niche pick for those sensitive to treble.

The reviewer finds the Tin HiFi P1 Max to be a neutral, natural-sounding planar IEM that behaves more like a dynamic driver, with excellent detail, accurate timbre, and a realistic soundstage. However, it is picky about amplification, requiring a more powerful source like the HiBy FC4 or a desktop amp to sound its best, as weaker dongles cause bloated bass and harsh treble. Overall, it is a pleasant and accurate listen, though it lacks a bit of bass authority and texture.

The reviewer considers the Tin HiFi P1 Max the best-tuned and best-sounding version of the P1 series, praising its flatter bass response and refined treble. However, they find the mids slightly recessed and thin, and the treble can be peaky on some tracks, which prevents it from making their top five. Overall, it's a decent planar IEM with excellent bass, but not perfect.
