Just ordered a pair in silver. Coming off Focal Elegia, MDRZ7 Sony and Beyer DT1770 Pro recently. Will be using Schiit Asgard 3 4490 as my only desktop dac/amp for the foreseeable future. Lived with the Beyer 1770 Pro for awhile as my daily. Liked them alright but ultimately they are monitors. Using these for album listening, film watching and some gaming. Break in period length?
Hard to quantify the break-in period in absolute hours. I'd say a period of 5 to 6 weeks of listening was good for me with around 10 hours of listening per week. You could just play them overnight (8 to 12 hours per night) for 1 to 2 weeks if you're in a hurry.
