Product description:

The Mission 731 has earned a reputation for delivering “surprisingly strong bass for a small bookshelf speaker”  ￼. Its tonal balance is often described as warm and non-fatiguing. A popular online feedback sums it up:

“The top end was smooth and not bright … the midrange … was beautifully open.”  ￼

On Reddit, a user noted:

“They have surprising bass for the small driver and cabinet. Detail ends in the mid range, top end is muted, and sound overall is very warm.”  ￼

While considered a solid value, they’re often categorized as Mission’s budget-friendly offering—some say paying over €90 may be “too much for the regular 731s”  ￼.
