Tin HiFi T4 vs KZ PR1

Short answer: the Tin HiFi T4. It ranks #277 of 450 in-ear headphones by sound quality, rated 3.9/5, at $89; the KZ PR1 ranks #354, rated 3.5/5, at $87.99. Close enough in price that the sound-quality gap is the deciding factor.

The Tin HiFi T4 is the better-sounding choice. It earns a preference score of 73 in crinacle’s measurement, and across squig.link measurements bass and mids stay within about 1.3 dB of target from 20 Hz to 3 kHz, giving natural voices and well judged bass. The tradeoff: In squig.link measurements a 6.7 dB dip near 10 kHz and about 3 dB less presence from 3 to 6 kHz take some sparkle and edge off cymbals and guitars.

The case for the KZ PR1: Its 13.2 mm planar magnetic driver is rare at this price, and crinacle’s measurement gives it a preference score of 67. The tradeoff: The squig.link measurements show a 10.5 dB peak near 11.2 kHz and air almost 12 dB above target, which can add glare and sizzle to cymbals.

Buy the Tin HiFi T4. It is rated higher for sound quality, and saving $1.01 with the KZ PR1 does not make up for the sound-quality gap.

Tin HiFi T4: $89.00 Amazon eBay

Pros: It earns a preference score of 73 in crinacle’s measurement, and across squig.link measurements bass and mids stay within about 1.3 dB of target from 20 Hz to 3 kHz, giving natural voices and well judged bass. Sub-bass is only about 1 dB down at 30 Hz, so kick drums keep their weight. At 32 ohms and 102 dB it runs from a phone, and it rates level with the Etymotic ER2XR for less money and above the KZ PR1 at a similar price.

Cons: In squig.link measurements a 6.7 dB dip near 10 kHz and about 3 dB less presence from 3 to 6 kHz take some sparkle and edge off cymbals and guitars. Listeners who want a brighter, more vivid top end may find it slightly polite.

KZ PR1: $87.99 Amazon eBay

Pros: Its 13.2 mm planar magnetic driver is rare at this price, and crinacle’s measurement gives it a preference score of 67. Across six hobbyist measurements on squig.link the bass sits about 4 dB above the Harman target down to 20 Hz, giving electronic and hip hop tracks a solid, rumbling foundation. It rates above the iBasso IT01S at about the same price.

Cons: The squig.link measurements show a 10.5 dB peak near 11.2 kHz and air almost 12 dB above target, which can add glare and sizzle to cymbals. Sensitivity of 96 dB is low for an in-ear, so a phone may need to run near full volume. The TFZ T2 Galaxy rates higher and costs less.
