Single 10mm dynamic driver with a neutral-leaning, Harman-like tuning
See Linsoul 7Hz x Crinacle Zero:2 In-Ear … on AmazonShort version: the 7Hz Salnotes Zero earned its reputation as one of the best first IEMs by getting the tuning right: neutral-leaning and balanced, with a detachable cable at an ultra-budget price. The newer Salnotes Zero:2, a collaboration with Crinacle, keeps that formula, and it’s the version to buy today.
Buy it if you want a balanced, accurate-sounding first IEM or a cheap reference set. Skip it if you want big bass (look at the Truthear Zero RED) or more detail (look at the Truthear HEXA).

What it does well
Balanced tuning. The Zero’s appeal has always been that it sounds right rather than exciting: vocals and instruments in proportion, bass that doesn’t spill into the mids, and treble without harshness. That makes it a good benchmark for judging other IEMs later.
A safe first purchase. Like the CHU II, it gives you a good tuning and a replaceable cable at a price where a mistake costs little.
Where it falls short
Bass quantity. The bass is tidy rather than powerful. Listeners used to consumer earbuds may find it lean until they get a good seal: our guide to fitting IEMs helps.
Resolution. It’s a budget single-driver set: busy tracks show its limits next to hybrids.
How it compares
| IEM | Choose it if… |
|---|---|
| 7Hz Salnotes Zero:2 | You want a neutral, balanced first IEM |
| Moondrop CHU II | You want the other default first pick at the same price |
| Truthear Zero RED | You want more sub-bass |
| Truthear HEXA | You want a clear step up in detail |

Verdict
The Salnotes Zero line is still one of the safest first IEMs you can buy. Choose the Zero:2 for its balanced tuning and replaceable cable, and step up to a hybrid when you want more detail.
