What's New in Marshall

1.3.1

July 8, 2026

Sometimes when things aren’t working someone has to step up and do something about it. We made some mistakes, and if we made you feel like it was your fault and that you hadn’t got a proper grip on technology, we’re sorry. Anyway, we fixed some bugs. We won’t bore you with the details.

一直连不上 wifi

重置后可以连上蓝牙了,不过并不能使用空间声学校准,EQ 也不行
wifi 死活连不上

Response from developer

Hi there, sorry to hear that. Please double check your Wi-Fi network is 2.4GHz and that your phone has a stable connection during setup, then restart both the speaker and router before trying again. If Wi-Fi still won’t connect and EQ or calibration remain unavailable, please contact us through the chat icon on marshall.com so we can help.

Not working at all after update. “Searching for” my Heston, again!

I love the Heston but thought the app was bad - it’s useless now as I have to start from scratch deleting and reinstalling, calibrating and sorting all the presets and saved radio stations again (which I hope are easier to find since the update and not hidden away). So disappointing - I wanted a radio station I had saved to listen to the news and missed it as Heston not recognised. I Hate Apps! Wish there were more controls on the unit so I never had to use a damn app. Never work when you want them. Always wanting updates.
