New BLON BL03 II vs Original - Is It REALLY Better?

TheHopelessGeek19.4K viewsFeb 2025

The reviewer compares the new BLON BL03 II to the original BL03, finding them visually and physically similar with only the connector and cable design changed. Sound differences are subtle, with slightly stronger sub-bass and altered treble, making it more of an incremental 'S' upgrade than a major improvement. The reviewer notes the higher price but still recommends it for new buyers, while suggesting existing owners may not need to upgrade.

BLON BL03 II They Changed EVERYTHING! (Is it better)

Prime Audio Reviews12.1K viewsJan 2025

The reviewer finds the BLON BL03 II a worthy successor to the original, with improved treble, detail retrieval, and a wider soundstage, though it is more V-shaped and can be slightly shouty. The build is better, but the stock cable remains poor due to aggressive ear hooks. Overall, it's a solid budget IEM, though not a massive upgrade for owners of the original.

in-Ear Fetish6.3K viewsJan 2025

The reviewer finds the BLON BL-03 II to be a decent budget IEM with a very wide soundstage and good bass for the price, but notes significant fitment issues that required modification and a slightly spiky treble. They recommend it for casual, non-analytical listening, valuing it at around $30-35.

Blon BL-03 II Review - Worth The Wait?

Vortex Reviews5.6K viewsJan 2025

The reviewer finds the BLON BL-03 II to be a mixed update to the original, with a better driver but a tuning that is not an improvement, plus quality control issues like channel mismatch and treble peaks. They are on the fence about recommending it, suggesting it needs fixes in damping, nozzle length, and cable design to be a truly good set.

BLON BL03 II - Let Music Burn

Paul Wasabii4.8K viewsJan 2025

The reviewer finds the BLON BL03 II to be a competent but divisive update to the original. While it addresses common complaints about the original's excessive bass and lack of treble, the tuning changes make it sound more generic and less unique, losing the magic that made the original special. It's a good budget set, but fans of the original may prefer the older model.
