TinHiFi P1 Max II Review: Best Budget Planar IEM for Bass and Clarity?

TinHiFi has been a well-known player in the Chi-Fi audio scene, and with the P1 Max II they are refreshing their line of planar magnetic in-ear monitors. The P1 Max II is a next-generation 14.2mm planar-driver IEM priced around $139, serving as the successor to the original P1 Max (nicknamed "Giant Panda"). It aims to offer both audiophiles and casual listeners a vibrant, fun sound signature with the speed and detail planar drivers are known for.

• Impedance: 16 Ω ±15%
• Sensitivity: ~98 dB @1kHz
• Shell Material: Resin housing with metal nozzle
• Weight: ~3.8 g per earpiece
• Cable: 1.2 m 4-strand silver-plated OFC, 0.78 mm 2-pin, 3.5 mm plug

Sound Quality

Bass

The standout feature of the P1 Max II is its tight, punchy bass. It delivers an impactful low-end for a planar IEM, with excellent sub-bass extension and mid-bass control. It's fun and energetic without muddying the mids.

Mids

The midrange is recessed, especially compared to its prominent bass and treble. Male vocals retain some warmth, while upper mids (female vocals, guitars) can be slightly forward—occasionally bordering on shouty or thin at higher volumes.

Treble

The treble is sparkly and detailed, but also bright. While it adds energy and air, it may be fatiguing for treble-sensitive listeners. Sibilance can occur, especially at moderate-to-high volumes.

Technical Performance

• Soundstage: Wide but not very deep; good width, average depth.
• Imaging: Accurate and well-separated in simpler mixes; slightly congested in complex tracks.
• Detail Retrieval: Strong; delivers plenty of micro-details thanks to the fast planar transients.
• Dynamics: Best when powered well; lacks impact at low volume due to its sensitivity.

Build Quality and Comfort

The shells are lightweight and well-contoured, making them very comfortable for long listening sessions. The swirling faceplate design looks refined and premium. The cable is durable, low-microphonic, and visually complements the shells. However, the absence of a carrying case or modular cable is a drawback at this price.

Design and Packaging

• Faceplates: Black base with 3D swirl pattern in white/grey.
• Tips: 9 pairs of silicone, 2 pairs of foam.
• Cable: Good quality but only includes 3.5 mm single-ended.

Amplification and Source Pairing

Due to its low sensitivity, the P1 Max II scales noticeably with power. A dongle DAC or DAP with balanced output (4.4 mm) significantly improves soundstage and dynamics. Out of a phone, it's usable, but limited.

Final Verdict
