The stereo speakers offer a wide soundstage and realistic sound thanks to their 360-degree design. However, like most speakers of its size, it does not have a thick bass and does not produce very loud sound. Unfortunately, unlike the JBL Flip 6, there are no sound customization features such as graphic EQ to adjust the sound to your liking. Unfortunately, while the audio sounds mostly clear and present, its mid and high frequencies are uneven and can sound alternately muddy and dull. That said, they are not very loud, but they are loud enough for use in a confined space, such as listening to a podcast in a small office. On bass-enhanced tracks such as The Knife’s “Silent Shout,” it struggles to produce a deep bass range even at a moderate volume. At higher volumes, there is obvious distortion, but at higher volumes, a kind of tape hiss is noticeably pushed to the forefront, rising and then receding between beats. This is an example of a DSP error, and it does not sound good; background noise often moves forward in the mix when the DSP limits dynamics to prevent distortion, as it appears to do in this case (a good DSP causes a dynamic limiting effect (They tend to focus on thinning out the strong low frequencies before) You don’t need to understand what I’ve described to know that songs with thick bass don’t sound very good on the HD77 when listened to at high volumes.
