Welcome To Luthermusic
Seems like Luthers has stock for new Sennheiser headphones:
"New Sennheiser Evolution series headphones are great for keyboards, digital pianos and mixing operations.
EH150 is just $49.00 and EH350 is $118.00. EH350 features flat response and is specially made for monitoring purposes, very suitable for home recording or "Live" mixing."
That $118 EH350 looks attractive for the price range!
