This is the new Neckband noise cancellation earphones released in Jan2020 by Sony not to be confused with WH-1000WM3(Over the ear) or WF-1000WM3 (True wireless buds).
I've been thinking to replace my BOSE QC30 with these pair. From the reviews the Sony one has better noise cancellation thanks to the same chip used in WH-1000WM3 and better sound quality with ldac. However, it may not be as comfortable as QC30 due to lack of shark fin earbuds for extended period of wear.
But this price is definitely a bargain!
Some may read this quickly thinking that these have the same NC as the WH-1000XM3's but just remember that they have better passive nc due to it being headphones.
