Truthear x Crinacle Zero RED vs 7Hz Salnotes Zero

Short answer: the Truthear x Crinacle Zero RED. It ranks #3 of 68 in-ear headphones by sound quality (rated 4.9/5) at $64.99 and is still sold new; the 7Hz Salnotes Zero ranks #4 (rated 4.8/5) and is discontinued, so it is only an option used. The 7Hz Salnotes Zero’s replacement, the 7Hz x Crinacle Zero 2, is rated 3.9/5 at $24.99.

The case for the Truthear x Crinacle Zero RED: A Harman score of 86 at an entry-level price delivers a well-balanced response with a smooth 1.1 dB deviation. Watch for: Presence from 3 to 6 kHz sits about 2.2 dB below target, so vocals and snare attack can sound a little recessed.

What the 7Hz Salnotes Zero does well: A Harman score of 84 from a single 10 mm dynamic driver at a bargain price is remarkable. The tradeoff: Presence and treble run about 2.1 to 2.2 dB under target, and a 6.2 dB dip near 10 kHz leaves cymbals and breath detail muted.

Buy the Truthear x Crinacle Zero RED. It is rated higher for sound quality and still sold new, while the 7Hz Salnotes Zero is discontinued.

The Two Headphones In Full

Truthear x Crinacle Zero RED: $64.99 Amazon eBay

Pros: A Harman score of 86 at an entry-level price delivers a well-balanced response with a smooth 1.1 dB deviation. Bass and mids track the target closely, and the dual dynamic driver design runs easily from a phone at 17.5 ohms and 117.5 dB per volt. It outscores the Tin HiFi T3 Plus by a clear rating margin at a similar cost. It is a good fit for listeners who like a warm, bass-forward sound.

Cons: Presence from 3 to 6 kHz sits about 2.2 dB below target, so vocals and snare attack can sound a little recessed. A 3.9 dB dip near 10.3 kHz and sub-bass about 1.4 dB light mean cymbals lack some shimmer and the deepest bass has less rumble. It is wired only with no mic or remote listed.

7Hz Salnotes Zero: $22.99 Discontinued Amazon eBay

Newer model: the 7Hz x Crinacle Zero 2, ranked lower, rated 3.9/5, released Nov 2023. See every 7Hz Zero generation.

Pros: A Harman score of 84 from a single 10 mm dynamic driver at a bargain price is remarkable. Bass and mids sit within about 0.3 dB of the target, so vocals and instruments are balanced naturally with a 1.31 dB deviation. It runs from a phone without difficulty at 32 ohms and 108 dB per volt. It beats the 7Hz x Crinacle Zero 2 on rating at a similar cost.

Cons: Presence and treble run about 2.1 to 2.2 dB under target, and a 6.2 dB dip near 10 kHz leaves cymbals and breath detail muted. Sub-bass is about 1.5 dB light, so the deepest rumble in electronic music is understated. The sensitivity is lower than many rivals, so it needs a bit more volume headroom from weak sources. Discontinued.
