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

Battery life sucks , the bluetooth connection is okay and this product only last me 3 years, i do not recommend!

Sound quality is decent. My gripe is about the connectivity. I bought two of these. The HK connect works, but it’s when you leave the area that the problems start. When you leave the home it disconnects (as expected) but when you re-enter the area the speakers recognize that you’re there but they don’t connect to your device. Then, when you go to your device (In my case my phone) to reconnect it connects but only plays for 30 seconds before it un-syncs automatically. You then have to physically walk up to the speakers to hit the Bluetooth button to reconnect and then use the HK sync. This was just very inconvenient and caused me to return them. If you don’t mind having to physically connect to these each time they might be for you.

LOVE LOVE LOVE this wireless Bluetooth portable speaker. The sound is much clearer and more powerful than the 3 others I tried, including the Bose Soundlink Revolve Plus which sells for $250+. Regarding the term portable - this speaker is larger and heavier than most portable speakers on the market, and I do NOT use it outside. For my needs, which is to have great-sounding music in any room, within the confines of my apartment, it is perfect. While it is not multi-directional sound, like the Bose Soundlink Revolve+, the sound quality is so superior, it renders that feature unimportant. For now, I have one of the HK Onyx Studio 4 wireless speakers, but I plan to buy another one, and two will link together to give true stereo sound. Still, even with just one, it is fantastic. The only small criticism I have is the way the volume buttons are difficult to locate/see. It requires good light and/or feeling around for them on the top of the speaker to find them. My fix: I set the speakers volume up to the highest level, and then use my iPhone (or my laptop, if Im paired to that) to control the volume - which works very well.

I love this thing. My inlaws have had one for about 4 years. Their battery is shot from leaving it on charge at all times but the sound is still good by the pool! I got one for my covered back porch and it is pretty decent. I unplug mine unless it needs a charge and hope the battery holds up for me. I recommend. I do wish I would have gotten 2 of the updated models so they can play in tandem. That would be awesome for outdoor entertaining!!! Do that! Haha Edit: the sound lowers when you take it off charge. It dies right away if you unplug it. I want to love this thing but I wish I would have went a different route. Id like it to be louder and more bass. Its very decent for sure. I almost ordered a second unit 3 or 4 times but I think I need a wired unit with multiple speakers. It just isnt loud enough. Decent speaker for rv camping or small spaces.

The sound from this speaker is absolutely amazing. I also have a Bose Bluetooth speaker and this speaker sound 10x better. It’s big though

Too pricey, could lower the price for product

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!

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!!!!

The sound coming from this speaker will simply amaze you. Easily fills the room with clean lows, mids, and highs. I want more of them!!!

I really like this speaker for several reasons. !. Great sound, the base is very clear and deep. 2. The high sounds are also crisp and clear, even at higher volume. 3. Its not to big and easy to move to where I want it. 4. Hard to beat for the price.
