I recently purchased this Harman Kardon Onyx Mini Bluetooth speaker from Kogan.com.au last month for $99.00 AUD. Most retailers in Australia sell this product for around $200 -$250.
This has honestly been one of the best value for money speakers I have purchased to date because of its portable size, connectivity and of course its sound. It boasts a nice bass sound from rear bass driver and clear sound from its dual tweeters. For 99AUD it was a steal.
Other Features included a 3.5mm auxiliary audio cable port, micro USB charging and Bluetooth hands free calling functionality. Battery life after a full charge lasts about 10 hours of non stop use which to me is fantastic after taking about 30min to fully charge.
Found this review of the speaker on YouTube if you are interested, seems to agree with what I think :)
Let me know if you purchased one and what you think of it
Thanks for reading
