Apos is an acronym for the type of company they are running. They have an F rating from the BBB. My experience: their site said the headphones were in stock (they were not!), Apos has Hifiman ship the headphones to me instead, headphones are stolen by UPS (per the UPS investigation). I did receive a refund but it took 3 weeks from ordering to refund. Again, they said they had the headphones in stock and this was a lie. Some research shows that Apos has a terrible reputation for support, actively avoiding emails until the item is outside the warranty period. I feel like I dodged a bullet.
