Conclusion

The ISN Neo3s have been a surprise, definitely not what I was expected!

They’re incredibly coherent with fantastic tonality, almost as if ISN challenged themselves to produce the least planar-sounding planar possible.

These are a solid choice if you’re looking for a set of dark, bassy IEMs under $200.

However ISN set a very high bar for themselves, so if you’re basshead I recommend spending the extra $90 on the Neo5s which remain my favourite IEMs under $300.

ISN did a great job implementing a planar driver without the usual timbre or coherence issues, and I’m very keen to see what they can do with these drivers in future.
