Harman Kardon Onyx Studio 4 Wireless Bluetooth Speaker Black (New Model, 100

It’s good but I don’t like how it doesnt last long probably an hour

Sound is great. Have some connecting issues at times. If I turn all the way up it start to sound like a cheap speaker

Bueno

Bigger then I thought thumps hard

To take full advantage of this awesome speaker, be sure to install the HK Connect app. The app allows you to connect two or more Studio 4 speakers (up to 100+) all from one Bluetooth source and guides you on how to setup either Stereo or Party mode. Stereo mode is obviously configured as two separate channels (L&R) where Party mode is full sound out of both speakers with no left or right separation. If youre on the fence about buying and think you should shop around more, dont! These speakers garner attention where ever I go. First thing they mention is sound quality, then how deep and distortion-free the bass is and lastly, how clear it sounds (better than Bose). Oh yeah, almost forgot... when I show them the HK app and can distinguish a Left & Right channel. They are BLOWN!

I had one that I got for free with my iPhone years ago. It lasted for almost 10 yrs. Which by today’s standards are pretty good. This new Harmon Kardon Onyx 4 is newer and so far we like it just as much as the original we had. Loud enough but not blaring loud. It does what we need it to do!!!!

I do not know about the battery life yet because every since I had, it has been plugged up in the wall outlet

I been wanting one for a long time finally treated myself. I am so glad I did I love it and so does my husband who every chance he gets will blue tooth his phone to my new speaker LOL. I love the size it is portable for outdoor yard work or the pool or work events!

Same speakers used in BMW. Portable. Clear sound, nice bass when listening to reggae. When not in use, speaker shuts off automatically. As far as using it with my phone, my phone needs replacing so I cannot say for sure how well it works on speakerphone but based on the other uses/features I would say it should work well. For instance, my phones music player is horrible; however, it sounds great using the speaker. Would definitely recommend and purchase again. Great product.

This baby generates great sound and above average bass for a blue-tooth speaker. You can actually see the driver moving while the music is playing. That is probably why the battery life is so short for this speaker (less than 2 hours at full volume). It probably takes a lot of juice to move the driver the way it does. If you dont mind keeping this plugged in, however, you are going to get a lot of enjoyment out of it.
