For what is worth, I had both sonos and bluesound speakers at my place for a while and I listened to them extensively side by side. I read through the review at digital trends and found it interesting. I agree that Sonos is the way most people will go for (due to price, availability at major retailers, word of mouth, etc etc), Sonos has more visibility and more consumers are more ‘exposed’ to it in various outlets.
Having said that, having tested bluesound speakers (Pulse 2, Flex) against sonos (Play 5, One, Soundbase) I reached very different conclusions that those in the digital trends review.
To my ears, the Sonos speakers have gradually changed their sound signature (I owned various sonos for more than 8 years) over time. While initially (Play 5 Gen I) sonos sounded quite balanced and warm … it now sounds (to my ears) very boomy and sharp at the same time. I found the Play 5 impossible to listen to for more than a few minutes. Tried Trueplay, manual eq adjustment, different placement… the lot. Very fatiguing sound.
The Soundbase was the worst with piercing treble requiring a drastic manual EQ adjustment. Unfortunately such drastic tweaking (treble all the way down) tended to degrade adjacent frequencies resulting in what I felt was a ‘hollow’ sound.
The Bluesound Pulse 2 on the other hand sounds much much much better even without the feature of trueplay. It just needs a bit of space otherwise it also can get a bit boomy (nowhere near the Sonos 5 though). The bass reduction via the EQ seemed to help a lot. The sound is detailed (vocals) and relatively warm overall. Very comfy pleasant listen.
The Sonos One sounds quite boomy and veiled but also distorts (bass popping) from 50% volume upwards. This is especially so when Trueplay is engaged. A problem regularly reported in the sonos forums.
The Pulse Flex to my ears sounds quite warm and without dynamics, especially at normal listening volumes. Quite boomy as well but the manual EQ can address this. No dynamics unfortunately but good with vocals.
The sonos app is amazing and the spotify integration is superb. In contrast I found the BlueOS app to be frustrating and badly designed with bugs. Despite indexing my iTunes music a number of times, playlists never worked and Bluesond recognised this as a problem pending fix.
I was considering sticking with the bluesound speakers but I became frustrated with the syncronisation issues (when in multiroom playback via Roon). I ended up selling both systems in the end.
There is always subjectivity with these things and one person’s clean sound is another person’s sibilant / harsh… but I have to disagree with the digital trends review’s assertion that Bluesound speakers have a ‘flat’ frequency response. It is just a different tuning but my sound analyser (and my ears) definitely found a warm (slightly emphasised) bass. Proper placement (lots of space behind the speaker) somewhat addresses this but I doubt this will be the typical placement in an average home.
Hope this helps a bit
