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

I love the crisp and clear sound. All thumbs up. I have a 7 also but the 4 is superior to me. Great purchase!

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

Great sound and easy to use

This bluetooth speaker is absolutely incredibly! The sound is rich and smooth, the base is heavy and balanced, the engineering of this product is stunning. The price is great for something of this calibur. The only thing is it states this is a portable bluetooth speaker. There are other speakers in its class which are lighter and easier to carry around. This is a little on the heavier and larger side to be considered portable but regardless it is great. I dont think this is waterproof or water resistant, but the reason we buy the speaker for its sound quality is a 10/10. Literally blows away other bluetooth speakers in its class, there is no comparison. This will fill up a room, full up a house, fill up your backyard for entertainment. I mean there really isnt anything else to say. The battery life states is 6-8 hours. Whatever battery life might not last the longest, other bluetooth speakers last greater than 10 hours. Regardless for its sound crispness and quality this is on a top level and for that reason no other bluetooth speaker, in my opinion, even really compares to this Harmon/Kardon Onyx Studio 4.

This is a great speaker. Sounds great. Be nice if had a little more bass. But still awesome. Very easy to connect to another Onyx 4. No need for the app.

SOUND QUALITY IS INCREDIBLE! HIGHLY RECOMMENDED

This is the best speaker for sound Ive owned and goes for a long time on a charge

I can freakin connect a hundred if I want to. Awesome bass and mids but treble could be better, that being said it is a great sounding speaker, goes every where and sounds great

Everything about this product is great except when I use the 3.5mm input, (from my pc for example) it takes about half a second for the sound to come through. There is no delay but it’s like the speaker needs to turn on again. This would be no issue if you just used it for music continuously playing, but for music creation, or similar and you need to pause for a bit then replay, you’ll need to wait that little delay and then replay it. ^ (This is not an issue with Bluetooth, ONLY thru the 3.5mm input) Other than this issue the sound quality is exceptional and I would really recommend.

If you like bass this is the speaker for you Looks and sounds like a subwoofer. I love this speaker best offer on the market quick to ship as well
