This is the place to discuss all things to do with the Meze Audio Poet:
Meze were kind enough to send one over for us to check out and review. The following post will contain primarily the measurement data, but here’s my personal opinion on it as well:
Measurements:
HpTF Variation
What is this? This indicates the headphone’s behavior variation across at least two different heads and ears (though anthropometric for both), providing a better indication of how they are likely to vary across human heads as well - absent other factors like leakage effects from glasses for example. Keep in mind, to the extent that these differ, that is not intentional, given both systems use industry standard ears.
Why is this? We have a video on the channel explaining why this type of visualization is likely necessary for headphone measurements. This should ideally evolve the more heads and ears we can test these products on, but the older paradigm of showing a single line on a graph to indicate headphone performance is insufficient.

GRAS 43AG-7 (KB5000 pinna)
Impedance curve
Note - this shows nonlinear impedance, which suggests the use of a passive filter (a good idea for tuning headphones), but it also means that running it out of a high output impedance device like a tube amp will significantly reduce the treble. Run it from low output impedance amplifiers to get its default sound signature.

Notes:
- Absolutely gorgeous headphone design
- Mechanically good as well, but I’m not a fan of the top headband wire style and prefer the way they did it with the Liric. Though I expect comfort to be very good for most.
- I think this headphone is going to be a bit polarizing. It measures reasonably well, but this is where we run into some of the downsides of the AMTS tuning method (DCA-style resonator network in front of the driver), where the in-situ performance ends up being quite different from the measured results. I feel there’s a risk of indexing too much for the particular ears used on measurement fixtures at the cost of consistent performance across real humans. So for those who hear it like the measured result, you’ll probably like it. But as with other AMTS headphones, this is bound to be a bit more variable as a consequence.
- Overall, this one isn’t for me personally, but I could easily understand why someone would like it a lot. I just feel you have to really be into this industrial design for it to be worthwhile, as the sound you get here isn’t the best at the price point.
