Great Marketing-still evaluating
Sennheiser's excellent reputation is intact with these headphones.
Currently evaluating integration with auxiliary phone device.
Minor Quibble (unless you wear glasses-mine were $$$$): the all plastic mouthpiece may "tap" your lenses if when not using, you raise the mouthpiece perpendicular to your eyes. Just requires alertness.

Kudos to "Product Support" dept. they sent the required adapter cable very quickly.

Caution: do not speak about technical matters with the sales ladies. They were 100% off base. Finally made it to Product Support and received excellent support.

Excellent service and product
I'm very happy with my order. After ordering online, I received a follow-up call to confirm the compatibility of the headset with my phone - excellent attention to detail. Further, the customer service rep was very friendly.
