I owned a pair of Bose x11s and worked with guys who run zulu
Zulus caused problems 4/5 had to be returned all fixed under warranty but a hassle.
X11 never missed a beat. I had the cord replaced once due failure it was due to self abuse and Bose replaced it free of charge. Very impressed.
Currently running uflymike on a Bose QC15 and will never go back to a traditional headset.
