Soundcore Glow Bluetooth Speaker ReviewBose revolve+ wannabe!
Soundcore Glow Overview
Frequency ResponseOverall in Signature (default) mode bass has a boost in the mid bass primarily at 80hz. However that big boost is dwarfed by the 12khz high end boost. Often used to add some air (apparently) I find a boost here to be quite unnatural sounding and can sound very electronic and sizzly. In real world tracks (these are frequency response measurements) I find that peak to settle around 10khz. At lower volumes we see a dip in the upper mids and presence region (1-5khz here) and a small dip at 8khz before that big high end push. As we go through the volume steps the bass and high end gradually fall off relative to the mids and by the time we hit 100% we are just left with mainly 200hz-800hz of audio. We can also see custom EQ mode in the app with sliders at zero is based on signature mode with bass on. The weirdly named balanced mode is simply a push in the 300hz to 900hz region and a relative reduction everywhere else in the response. How on earth is that anything to do with some sort of balance? It is very hard to understand the point of this EQ especially to pass it off as a more balanced mode.
Soundcore Glow – Sound!
I did my testing with the Soundcore Glow in signature mode with bass on since bass off is a big bass cut in reality.
The most obvious comparison would be with the Soundcore Flare 2, a speaker that came out 4 years ago. The good news is that the Glow is indeed an upgrade over the old timer. The 10-13khz boost on the Glow however is very evident and can be annoying if your tracks already have peaks there. The bass digs deeper and has a better quality than the Flare 2 but its not all good news. The lack of upper mids means the 10-13khz peak is even more in focus as that’s what the Soundcore Glow relies on for its clarity. At moderate volumes bass is reasonably strong for a speaker this size but falls off rapidly from 75hz. At louder volumes relative bass falls off rapidly leaving the high end sizzle. By maximum volume even the high end falls away and you are basically just left with 200hz to 1khz for the volume. While playing my test track for loudness the Glow was hitting 98.8 dB(c) at 1 meter.
Soundcore Glow – The competition!
I compared the Anker Soundcore Glow to some other 360 degree type speakers.
The Soundcore Flare 2 (£89/$66 at time of review)
The Minirig MK3 (£99)
Tribit Stormbox Pro (£99/$99)
Bose Soundlink Revolve+ V2 (£250/$230)
Vs Bose Soundlink Revolve+ V2:
To my ears the Soundcore Glow is clearly tuned to sound like the Bose Revolve+ but it lacks the upper bass of the revolve albeit the Revolve+ is boosted in the upper bass while the Glow then boosts lower mids which counters this to some degree. Both lack upper mids but the Revolve+ is more V-shaped so also loses some lower mids. But its that unnatural 10khz+ peak of the Glow that always sizzles though for me. Not in a good way. On a quick A/B The Glow may sound clearer but that’s due to the hgihs boost which depending on your hearing and tracks may be a welcome thing or a nightmare. Overall I found the Bose to be warmer and smoother but a bit muddy due to its bigger dips in the mids. The Soundcore Glow in comparison I found thinner brighter sounding but does make up for the dip in upper mids with its high end boost, whether you like it or not is a different matter.
while Soundcore Glow has a big dip in upper mids and big boost at the high end. In terms of bass the Glow does have the edge but the Flare 2 actually has stronger upper bass and lower mids. Again in the real world they actually sound quite similar at these lower volumes but ultimately the Glow plays cleaner and the Flare 2 is slightly gurgly. I don’t know if its just my unit now since it has had a lot of playtime since I don’t recall it being quite that bad when I first bought it. Its win for the Glow in any case, it’s bigger in size and sounds better to my ears.
Vs Minirig MK3: The Soundcore Glow sounds more sparkly while Minirig mk3 sounds a tad hollow as the mk3 has a bit more in the upper bass but mid bass advantage is to the Glow now. When listened at 45 degrees with driver firing straight up the mk3 is a little too rolled off in the highs and dull/hollow sounding to me as bass rolls off quite considerably as you push the volumes. I might just give a win here to the Glow for a little bit better balance but remember how you listen to the Minirig mk3 will very much change how it sounds.
The Bose Revolve+ is more V shaped than the Glow resulting in stronger bass but its mids are a bit recessed even compared to the Glow and as a result this is robbing some clarity for the revolve+. The Glow is more sparkly and harder edged sounding due to a 350hz peak and still has its high end boost so it’s a matter of taste here but I need bass personally so Revolve+ wins for me. Ultimately there is just a hint of extra quality and fullness to the sound of the Revolve+ that makes it the winner for me. but given the price difference that should not be a shock. The difference in quality is less than the difference in price. However the Glow just sounds too safe and too brittle in the highs for my taste.
Ultimately the Soundcore Glow is a pleasant and safe option but the Tribit Stormbox Pro offers more at a similar price. If you are not a bass fan and like a sparkly sound then you may still prefer the Soundcore Glow. For me the dip in upper mids and unnatural 13khz boost makes it a bit off for me but not awful and certainly better than the smaller and older Souncore Flare 2. At 75% my preference is the Bose Revolve+ over both the stormbox Pro and the Glow where I find it just has a bit extra quality to the sound that my ears are in tune with. However this is a sweet spot for the Revolve+ as it is muddy at lower volumes and its crazy price means I cannot recommend it while the difference to the stormbox Pro is not much. We are soon to get the Minirig 4 which I hope has a bit more deeper bass over the upper bass punch of the mk3 and less of a focus on volume over bass at near max loudness.
