It varies by device. The Echo Plus and Echo Studio are specifically designed to have better sound quality than the average Echo. You can also always try adding Amazon Echo Sub to your existing speaker to get a better bass sound. However, the sub is currently unavailable on Amazon, so you’ll have to look at another retailer to get it. We definitely wouldn’t recommend the Amazon Echo Dot. The sound isn’t bad with Dottie, but it’s too small to have major resonation for a bass line. Overall, if sound is your main concern, you might want to look at sound-first products like Sonos speakers.
