The SRS-X55 is the largest speaker of the 3 portable wireless speakers announced by Sony in May. The smallest SRS-X11 is a mono speaker that can be linked to another X11 for stereo, while the SRS-X33 achieves brilliant treble and deep strong bass. How does the X55 fare? Read on.

There is no doubt that the X55 is made for loudness. The 2 full-range speakers pump 30W each, while the dedicated subwoofer produces 20W. When plugged into AC power, the speakers can go even louder. When playing with wireless devices that support LDAC codec, like the NWZ-A15 Hi-Res Walkman, the high frequency delivers with clarity and distortion-free. Like the X33, the X55 delivers clear treble and boomy bass. It also has a full-size USB port for charging USB devices, so it will be useful for emergency.
However, the audio balancing between the highs and and the lows of the the X55 is less ideal than the X33. Like the X33, the X55 is skewed towards clear treble forgoing the warm mids. Yet, the X33 allows more bass to level up with the treble while the X55 does not deliver the corresponding low-bass impact despite having a larger dedicated subwoofer. At high volumes, the kick-bass from pop music like Royals by Lorde turns out with slight distortion as vibrations can be felt around the unit. Instrumental genre fares a lot better, as the sound mix is even across the spectrum – sustaining bass notes instead of hard beats, prominent instrumental lines at the mid range, and clean percussions at the highs.
The X55 is clearly built for loud hi-fi quality audio, but at high levels, the subwoofer cannot match the treble discipline. The X55 is better-suited for instrumental music, where bass are generally more tamed and sustained than modern genres.
