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

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.

I’ve always want to buy this HK speaker and finally I got one. It is the BEST!! The sound is outstanding, crisp, and perfect sound!! NO DISTORTION when I play my music load!! since I’ve purchased this in DEC 2020 for Xmas, I play my music everyday while working from home!! A Couple of my friends have the older version of this speaker and that’s how I fell in love with it. Highly recommend this to everyone!!!!

This thing is great. It was quick and easy to set up. They give you multiple plug-in types so not just United States but other countries as well. No complaints and the sound is really nice.

This speaker packs huge bass and is great for on the go. There are a lot of immitations out there on Amazon and other places but when you compare the specs, some have to be plugged in to work and other just have smaller less powerful speakers. I thought about cutting some corners and saving some money but for how I use my speaker, this Harmon Kardon speaker is the BEST value. Battery life is good (about 4hrs on the highest volume). It paires quick and easy like pair of headphones. I got at least 30ft away with no signs of Bluetooth connection degradation.

This speaker is the truth!!! I absolutely love the versatility, light weight and the sound is incredible, the battery life could be a little longer

I’ve had an Onyx 2 speaker for many years, and it still works great. So I knew these speakers were a good value. At some point I managed to drop it and break the legs on it, but it still functions fine. The Onyx 4 I ordered was at a good price, and it is essentially the same as the Onyx 2. I was a little disappointed the 4 doesn’t have a removable speaker grill. I can’t tell if it’s built the same as the Onyx 2z Overall I am very happy with the purchase and expect to use it for many years.

I needed a really good new bluetooth speaker to play my vinyl records on which has bluetooth connectivity on it (technics) and I was thrilled with how loud and powerful the speaker was! I love a speaker with good base and it freaking delivers to me. I feel like this was such a great investment that I had to buy two just to fill my living room with such a crisp sound. Only downfall I had with this is when you pair both speakers to connect simultaneously with the feature it has, its a little spotty and was surprised because these speakers arent far from each other and there is nothing blocking it to not receive the proper connection but I have only experienced this when I use my phone on it. When I play my vinyl records its perfectly fine. Maybe its the cellphone connection but other than that Im still happy with this purchase!

I went on a trip aboard a small cruise ship last year and they had the Onyx 3 onboard for us to use... was impressed with it then whether on the ship or on any of the small islands we visited. Again, recently I stayed in a nice hotel in Singapore whose suites had the Onyx 3 in them, and that did it for me. It just sounded so good. So I bought the successor, the Onyx 4. Though I had some minor concerns about this being a knock-off, given the good price, it sure seems to be the genuine article in every way, from packaging to documentation to (most importantly) performance. Sounds terrific, syncs up effortlessly, and even came with several different plugs to use, which is great for me since I live overseas. The adapter itself is universal voltage, which I knew, but didnt expect the bonus of four different plugs being included, which precludes the need to use a plug adapter. The plugs included were North American, European 2-pin, UK 3-pin, and Australian angled 2-pin. Ive been very pleased with the sound quality and battery life. With two woofers and two tweeters, plus good porting, the Onyx 4 delivers nice bass and excellent room-filling sound overall, in a portable unit (weighs about 2kg/4.5 lbs). There are so many Bluetooth speakers out there, its hard to know which is the best, but the HK Onyx 4 sure does a fine job for my needs.

Sound is amazing. It has depth. I have bought two previous Bose (one within the recent month of purchasing this) which I thought had great sound, but this doesn’t compare when it comes to sound depth( base) I wish the battery lasted a little bit longer. I am very satisfied. This was recommended by my friend, and I doubt I will go back to a bose.

Amazing sound quality. I don’t get how they do it!
