Quality and style Combine Klipsch's peerless sound clarity and retro style with portability and compact body. That's exactly what you'll get with the Klipsch Heritage Groove Portable Bluetooth Speaker, the smallest Klipsch speaker made to date. As is customary for the entire portfolio of Klipsch, the speakers are made with high quality materials including tactile spun switches and knobs and real wood veneer used for the body, as can be seen on the top and the bottom. The sides are wrapped in a beautiful fabric. Heritage sound and design This portable speaker offers crisp highs and a surprisingly deep bass that are all being produced using a single 3” aluminium full-range driver. This driver is located in a sealed cabinet and the lower frequencies are further improved with two passive radiators on the back. Besides the powerful driver, the manufacturer has also included advanced digital signal processing to optimise the sound according to the volume. This innovative DSP technology will help bring out the legendary Klipsch sound - full of detail and dynamics. To go with the sound quality heritage, this speaker and the whole Klipsch Heritage line features mid-century design. The walnut body is covered with retro grey fabric, and the minimalistic look is completed with simple controls on the top. Easy connectivity And while this speaker looks vintage, it also offers the essential modern connectivity options. Simply pair your smartphone, tablet or laptop using Bluetooth, or use the 3.5 mm jack to connect to your devices. The internal battery with a capacity of 2200 mAh will allow you to blast music for full 8 hours. When you run out of battery you can use any micro USB cable or the included charging adaptor. And with the built-in microphone, it is also ready for hands-free calls.
