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

The sound is incredible compared to less expensive Bose I previously purchased. Perfect for my great room, where it will always reside. I dont have a need to take it outside. I am leaving it plugged in to wall socket. Looks nice in a corner of my kitchen counter, sitting on top of my small radio - which is elevated. This corner is far enough removed from sink and splashes but elevated just in case:) It appears I ordered just in time, too, as price has increased by $30! I am pleased.

I love this speaker, I love the sound quality and the bass is amazing also, pretty good material quality so far my favorite speaker I’ve ever owned. The only thing I don’t like about is that it has a short battery life which I don’t mind because it sounds better when you have it plugged in while it’s playing music.

Sounds good, but could have been better from what I have heard from this type of speaker in the past

It was a Christmas gift and I didn’t receive the charging cord and would like to know how to receive one. This is my second purchase of same item and I had no problems with the first one. I am not satisfied with this purchase

Mine just arrived less than 20 minutes ago and I got it up and running already. It is a bit large... larger than my Bose speakers... but the SOUND! Oh my GOD! I was able to hide it behind my guitar in the corner of the room - the sound is so big and rich its amazing! I cannot rate the battery life as this is something I have no plans on using - this speaker will be all but permanently mounted in my bedroom and hooked up to Alexa. I gave it a 5 because Im so happy with everything else. Im sure the neighbors will not be as pleased as I am as with such a great speaker, I should probably put sound insulation on our thin walls! :)

Great room filling sound. Speaker likes to be pushed to higher volume levels. Excels in lower bass notes. Noticed if I carried my phone around Bluetooth signal gets lost. Would have loved additional treble and bass on speaker or tone control.

I am extremely disappointed in this speaker, speaking as someone coming from a first generation Harman Kardon Studio speaker that I purchased May of 2015. First and foremost, the sound quality out of the 4 is half of what the 1 puts out still to this day. High range is clear, mid range is cloudy and boring while the bass is underwhelming, especially after reading so many reviews praising the bass quality. Frickin lol man. Once you hit ~20% volume the bass caps out and doesnt go any further. My gen 1 booms in my room whenever I have it playing. Secondly, I bought two #4 speakers in order to pair them in a party environment in order to keep the volume consistent across the house. First impression when downloading the app off of the App Store, was the amount of negative reviews. And you can also see the same comments in the 5 star reviews. PAIRING WORKS RARELY / IF AT ALL. Two brand spankin new speakers and they consistently unpair, crackle, pause playing, lose sync and play out of turn, fade in and out, etc. Not even 15 minutes into the pairing session and they were having issues. My second speaker, while still at half charge, decided to shut off after 5 minutes of playing just today while out in my garage. Turned back on, resumed playing, and 1 minute later turns off - the other speaker, which has been on the same length of time as the first speaker worked fine out in the garage. The build quality of the speakers seems fine and refined. Seems like a quality product coming out of the package. However, being in 2018 you would expect a QUALITY company like Harman Kardon to be able to produce speakers that 1) can sync just like most other bluetooth models 2) produce a clear sound 3) have some kind of bass quality. Read the other reviews where users just shrug off the aux cord not working... what? When is that ever acceptable? Aux cords have worked perfectly for YEARS and this speakers fails to do something so simple. Okay sure, the speaker can get loudish, but the quality is highly distorted, it cant pair with other speakers efficiently, and Im already having defects with one of my speakers. Currently listening to music off of the working speaker while writing this review and Im still disappointed. Incredible how they could make something they had made perfectly before into such a failure of a product. Safe to say I will not be purchasing from HK any longer. Both units are being returned via mail tomorrow. Truly disappointing.

The sound are really good

Ive purchased two Onyx 3 speakers and one Onyx 4 speaker. Both of the 3s (purchased in 2017) are performing extremely well. The 4 (purchased in 2020) is quite a disappointment. The battery holds no charge and the speakers crackle at mid volume. Im looking at replacing the 4, but Im not sure it will be with another HK product.

Probably my favorite portable speaker of all time.
