Superb, ideal for Bassy music
Pros -Very bassy, makes modern music (e.g Post Malone, Drake etc) sound amazing.Can still provide a clear sound for less bassy genres; I’ve recently been listening to some UB40 and it sounds fantastic on the HKBattery life is good, will last a night of playing music quite loud, ideal for party scenarios. Sound fills the room.If you were to buy two, you can link together using an app, which could turn your house into a small nightclub.Cons -Can provide too much bass on songs that wouldn’t usually have bass.Quite large but produces sound of a much bigger speaker

Quality
As someone else review, I am not someone who normally completes them.Did some research on this before purchasing and its quality is amazing.All I can say is get this, you will not be disappointed.Amazing sound, for all genres of music, its becomes noticeably bassier when plugged in, but saying that was 100% happy with it just sitting on the side playing music, great quality, great sound, cannot rave about this enough

Buckets of bass
For £145 this can't be beaten.It's a bit of a big lump to call portable but as a home speaker it's amazing value.I've not tested it for battery life as it's just used as a home speaker. Granted top frequencies are a bit muddy but what do you expect for this sort of money ? A neighbour has a Bose speaker costing £100 more and I can't tell the difference.Give it a go - you won't be disappointed.

No better speaker under £250
It’s not the most portable but it is the best sounding speaker under £250 by a wide margin. You simply don’t get decent bass from small units which the HK delivers in droves along with treble that has none of the harshness small units have.I now have two of these (you can daisy chain as many as you want) and you can play in stereo or duplication mode using the HK app. Two sound awesome and for parties the volume and quality is well worth the expense,

Very loud speakers
Very good sound and has excellent base, however battery life when off charge doesn’t last long and the base and sound is better when it’s plugged in.

Best bass in a budget speaker
Amazing. Loud and boomy. Sounds like I’m at a concert super bass and crisp highs, very happy with my purchase :) thank you Harman, I use this mainly plugged in at my desk and it has never died even when I took it out else where and when plugged in it is louder and a small bit bassier I am in love with the design, looks very expensive!! I love it!! :)

Please keep producing these!
Absolutely fantastic product. I have bought three studio 3’s one studio 4 and a mini onyx and a pair of 4’s for friends in the US. The sound quality is stunning. What a shame they are so difficult to find now, there is nothing of the same quality for the price in the market currently... in my opinion.
