Coming on the heels of its X100, Logitech’s X300 Mobile Wireless Stereo Speaker ($70) is the second of the company’s new speakers to bear only its branding, and not the Ultimate Ears name. The two units are clearly part of the same line, with the same materials and aesthetic touches. Instead of a single-driver speaker, however, this one houses more drivers, in a larger — but still portable — package. Available in black, red, blue, or purple, it ships with only a Micro-USB cable for charging its five-hour battery; X100’s integrated carrying cord isn’t present.
X300 is roughly Jambox-sized, measuring 6” across, and almost 3” tall and deep.
It has an unusual teardrop shape, round at the front and narrowed towards the back, creating a steady, reclined angle. The plastic body is mostly covered with rubber, although there’s a triangle-patterned, bow tie-shaped grill that extends all the way across the front and around to the left and right sides. In addition to the distinct volume and Bluetooth buttons along the top, there’s a less visible power button towards the bottom of the unit’s back, with aux and power ports in the opposite corner.
The speaker appears to be a four-driver system with two front-firing active drivers and two side-mounted bass drivers. As we’d expect, it definitely outperforms X100 when it comes to low-end performance. You won’t be overwhelmed by the bass, but it’s certainly more pronounced thanks to those drivers, which the smaller speaker lacks.
This results in a much more balanced sound profile. The highs and mids are comparable between the two, but music from X100 sounds harsher in comparison. X300 also has the benefit of somewhat narrow, but definitely present, stereo separation. Compared to the original Jambox, Logitech’s latest actually gets louder, but the former is a bit clearer overall. As for speakerphone performance, X300 offers volume levels and a sound signature just about identical to the iPhone’s, but is slightly more muffled.
