Telex 850
Hi,
since youīre asking about those specific models I donīt know if this helps - but I can say I am more than happy with my Telex 850. ANR through the normal plugs, no batteries and small enough to fit in every flightbag.
Compared it with some Sennheiser ANRīs (much bigger) and I can say I made the right choice. And I wouldnīt call the Bose X a leightweight ;-)
Regards,
TL
