These are not really the same size class, and that is the honest framing here. The Amazon Echo Dot 5th Gen ranks #11 of 14 powered desktop speakers by sound quality at $79.99; the Brane X ranks #4 of 105 large speakers by sound quality at $549.
The case for the Amazon Echo Dot 5th Gen: What Hi-Fi rated it 5 stars for sound, calling it expansive for its size with great Alexa integration and an understated look, from a single 44mm front-firing driver. The catch: What Hi-Fi’s one real complaint was distortion at higher volumes, and bass force and detail both fall off at the low end, typical for a speaker not much bigger than a hockey ball.
The Brane X is the battery-powered, tougher choice. The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 7.7 lbs (3.5 kg) portable: its measured -10dB extension is 31Hz. Its battery is rated for 12 hours, while the Amazon Echo Dot 5th Gen needs an outlet. It is rated IP57, while the Amazon Echo Dot 5th Gen has no water resistance. It supports aptX HD Bluetooth, which the Amazon Echo Dot 5th Gen lacks. Watch for: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
Buy the Amazon Echo Dot 5th Gen at $79.99 for a powered desktop speaker, or the Brane X at $549 for a large speaker instead.
