Overall they are comfortable for me for ~2-3 hour listening sessions, and I have an average size head but large-ish ears.
With a bit of EQ they are really enjoyable, detailed, and well-balanced, and provide respectable imaging and soundstage. No, not a Flagship killer, but very respectable given the price.
Yes, the build quality could be better overall. The vertical pivot/articulation of the yokes is poor, the headband padding is not so great (but comfortable enough for me), the weak point of the magnesium headband extension/yoke stems is questionable, and the touch gesture control is finicky, etc.
I'm also not a fan of plastic simulated woodgrain. But some inexpensive 3M vinyl wrap in your preferred color or design is an easy fix for this.
We have to keep in perspective that these were a Kickstarter/Indiegogo crowd-funded endeavour, using a new and unique technology, by a startup that hadn't produced headphone products before. So what should any of us honestly have expected?
Ultimately, for ORA Sound, it was a cost-effective way to conduct a proof-of-concept (& technology) experiment using an extremely popular product category, which could then be applied to wider reaching lucrative market segments and contracts, such as OEM HDTV manufactures and OEM automotive audio systems, Bluetooth speakers, budget to high-end loudspeaker manufacturers, Motorola-type portable 2-way "walkie-talkie" radio speakers, etc.
Given the price I paid (IIRC ~$260 USD for each), I'm very pleased with them. They incorporate many convenience features that few others offer at that price point. And they are very pleasant to listen to IMO, and even better with a touch of selective EQ.
I liked them well enough to sell my 1st Gen Beyerdynamic T1 and 250-ohm DT-880 Premiums, so take what you will from that.
EDIT: And IMO, with EQ, they clearly sound better via a direct wired connection rather than BT. But this may also depend somewhat on which codec your BT playback source is using to transmit the wireless audio.
