Marshall Stanmore II Voice (2018) vs Audio Pro Addon T3 (2015)

Analysis:

The Marshall Stanmore II Voice (2018) is a great Portable Bluetooth Speaker for its $395 asking price.

The Audio Pro Addon T3 (2015), however, while a reasonable product for $149, doesn't stack up against its competitors quite as well. If you're considering Portable Bluetooth Speakers in the $200 range, you might want to check out some better options.

Two highly trusted sources that perform well-thought-out in-depth testing consider the Marshall Stanmore II Voice (2018) to be a great product - it earned the "Also great" title from Wirecutter (NYTimes) and "Best sound" from SoundGuys in their respective Portable Bluetooth Speaker roundups, which is a good indication of it being a notable product.

Taking a look at the Audio Pro Addon T3 (2015), it got featured in roundups from two reliable sources that conduct their own testing - Expert Reviews and What Hi-Fi? - but it fell short of earning a top spot in either.

We couldn't find any sources that tested both of these Portable Bluetooth Speakers, so we only analyzed how they performed in reviews from different sites.

We first examined which sources rated each of these best and found that the Marshall Stanmore II Voice (2018) got its highest, 9, rating from TrustedReviews, while the Audio Pro Addon T3 (2015) earned its best, 10, score from Expert Reviews.

Lastly, we averaged out all of their review ratings and observed that the Marshall Stanmore II Voice (2018), with its 8.1 average, performed considerably better than most Portable Bluetooth Speakers - the mean score for the product category being 7.6 out of 10 - while the Audio Pro Addon T3 (2015) managed an average of 10.0.

There's one caveat here - it might not be entirely justifiable to do a direct Marshall Stanmore II Voice (2018) vs. Audio Pro Addon T3 (2015) review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
