Same price on Amazon AU. The cheaper AZ40 is going for $149.
I have an older model AZ70 and easily one of the best sounding earbuds.
More suited for someone looking for better SQ rather than noise cancelling. Personally not of fan of Sony as the NC tend to be overkill and distorts SQ.
Marketing write up below:
Thanks to 8mm drivers, a special acoustic structure and category-leading noise cancellation, Technics latest AZ60M2 earbuds give you a clear sound advantage – wherever your busy day takes you. With a comfortable design, seamless device switching and crystal-clear sound quality – you won't miss a beat.
I got rid of my Bose QC Ultra for these and while the ANC is nowhere near as good as the Bose, almost everything else about these is better. They are a pleasure to use compared to the Bose.
