Harman Kardon is now offering its Onyx Studio 4 Portable Bluetooth Speaker for $99.99 shipped in black. Originally $450 and still fetching as much directly from Harman Kardon when not on sale, they go for around $149 via Amazon third-party sellers at the moment with today’s offer matching our previous mention and the lowest we have tracked. The higher-end fabric finish stands out on this model along with the unique form-factor. This Bluetooth speaker packs in 8 hours of battery life and features one-button access to virtual assistants (both Siri and Google Now) alongside dual noise cancelling microphones, the ability to connect up to two wireless streaming audio sources at the same time, and high-quality HK sound.
