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.

Heston 120

App works great, easy to set up my awesome Heston 120. I just don’t understand why it’s a separate app from my other Marshall products, now I have two Marshall apps. I wish it had equalizer presets like my other Marshall app, that way I can easily toggle from “the Marshall sound” and custom presets.
