Pros: Clear and punchy bass; sound seems natural, flat and clear, cool design, not too expensive, controls on speaker
Cons: Off/ bass amount button is on the back of the sub, light on sub when system activated (not very bright, thankfully), limited choice of inputs
I bought these to replace a cheaper set of speakers which broke, and I'm honestly quite happy with them.
I usually listen to FLAC on ATH-M50 headphones through a Fiio E17 (Alpen) DAC, so I expect relatively clear sound. I was not disappointed
The Harman/ Kardons SoundStick III was decently priced at $150 Australian Dollars at CostCo, and I new from the review of the SoundStick II that I should expect good quality speakers.
The bass is punchy as hell, and really clear, and the mids and highs feel really well balanced and nice and sharp. The sound is really encompassing the room, and the cool design adds to the pull of these speakers. Jazz sounds so clear, techno is punchy, colourful and alive, and classical is just indescribably well-rounded, sharp, clear and simply lovely. I am extremely happy with the quality of these.
The only things I can really criticise are design 'flaws', such as volume/ mute controls cleverly placed on the right speaker, whereas unfortunately the power/ bass level knob is oddly situated on the back of the sub. Also, there is a white light on the sub when the system is live, but it's not TOO bright, which is good. To be honest, these aren't really that bad, I just thought I'd mention them. There aren't a wide array of inputs available - although some adapters came in the box - but I don't mind since I'm using the AUX out from my amp.
All in all, I'm really happy with these speakers, so I'm giving them a 4.5/5. I'm obviously no expert on sound quality; but the Harman/ Kardon SoundStick III has that magic, beautiful sound that you look for in a listening device.
