Loved them to death. The sound was impeccable. I would sleep in them to drown out noisy neighbours. They made listening to podcasts feel like the people were in the room, which could be disconcerting as I live alone. They made Whitney Houston come alive but where they really showed off was with classical music. My hearing loss is moderate (due to listening to loud music since the womb) so these were able to rectify my losses. The Bluetooth had a really long range too, so you don't have to have your phone on you, it could be 3 rooms away. I have since upgraded (due to wearing them out) to the AO2s, which are also incredible.
