Priced $399 locally at Addicted to Audio, the Shure SRH840A is the upgraded version of the very highly rated SRH840.
Targeting the same sound quality as its predecessor while weighing less and boasting better comfort.
One of the most highly rated closed backs in Crinicle's Headphone Ranking List. Which is based on scientific measurements and he is subjectively neutral oriented.
I'm sure you have your favourite reviewers, see what they say about the original SRH840, or even better if they have an updated review of its successor.
Disclaimer: I have not tested them, nor do I own them, so I cannot give my personal opinion on them. Nor do I plan to buy them, but I saw they are decently priced on Amazon and decided to post for others.
Anyone know how these compare to dt770s?
