W-KINGPortable Speakers Bluetooth Wireless Loud, 100W Max Waterproof Outdoor Bluetooth Speaker Big Party Large Boombox Subwoofer*2, 60W Exlarge All-Round Bass Passive Radiator/40H/PowerBank/TF/AUX/EQ

I have recently brought the latest edition to W-KING Bluetooth speaker range, the D9.To note, I have also brought two of the previous W-KING models, the D8, which is a 50-watt max output unit. This was so I could pair the speakers. You can pair this latest D9 model with another D9, but cannot pair D8 and D9 units together.This model, the D9 is now upgraded to 60-watt max output.Both models are similar in weight, both are of a solid and sturdy build quality, which is reassuring for me. Both in black colour and the front grille design is on both models.The noticeable changes are firstly the handle, which as my pictures show is now solid plastic, instead of an adjustable fabric carrying strap. The strap would allow user to carry out and about, over their shoulder, now the user will have to hand held. It depends on how the user is going to use the Bluetooth speaker.The passive radiator/speaker is exposed at the back of the unit, which is a shame, and I would have preferred more protection, as it could get damaged.There’s an increase in battery life, reported to be now from 8000mAh rechargeable battery on the D8 unit, to now 12,000mAh rechargeable battery on the D9.The button control display is the same, with the option for sound boost for indoor and outdoor use.The D9 unit comes already charged, so its plug and play. Easy to Bluetooth and connect. Leads are also included for charging, and if user wants a wired connection instead of Bluetooth. Equally, D9 unit allows MP3 player or smartphone to charge.The D9 unit is now of a IPX6 waterproof construction, which means it is protected from powerful water jets, but does not mean you can place this unit in a swimming pool or prolonged raining.I have tested the sound against each other, and in my opinion the D8 still sounds too tinny, with not enough bass. The latest model, the D9 does have an increase in sound and power output, and a noticeable increase in that of bass, but it is by no means as much bass as I personally like, I am a bass beast. I just hope that further W-KING models in the future install better more bass responsive sub woofers.I could upload a sound video, but I find these of little use as the sound quality is dictated by the laptop speakers or smartphone speakers being used to view the video, and never get a true representation of the sound from a speaker.Would I recommend this D9 unit, the short answer yes, but would advise, do you homework first, ask yourself, what am I expecting this speaker to do, and how do I plan on using it for, and test it.For the price, its value is good, against other Bluetooth speakers, such as JBL or Bose, which obviously have a more richer, deeper bass, and overall sound.

Brought one last year n have had no problems with it, sounds are pretty sharp and the bass is pretty good for what it's worth.Battery last for a decent long time and the controls are simple.Just Brought another one to see how the paring future works, coming tomorrow so will up date

Summary: I reckon this speaker could comfortably handle a 30 person house party, whenever those are legal again. You can really feel the sound pressure / bass, which I've never experienced from a portable speaker! Outperforms the competition 2-3x its price.(If updating the firmware, which I would recommend: The speaker should be switched off before you start following the instructions. That threw me for a while! It's very straightforward after that)Indoor performance: This speaker is seriously loud - I haven't been able to test it at even close to full volume since we're still in lockdown, but I can confirm it goes extremely loud, and the bass is pretty physical. The equaliser button really does crank some bass out - the bass is audible throughout the house even if the music itself isn't. Your neighbours may be less thrilled about this.Outdoor performance: I have tested it in my garden and the bass performance in the open air is also incredibly impressive, even at lower overall volumes. I'm not sure when I'll encounter a park empty enough to really crank this to its fullest (I maybe got to 20-30% volume in my garden before thinking about the neighbours).Battery life: It's not close 40 hours for me, up to ~12 depending on how much I want to feel the bass in my bones. Given I don't expect to be using it for more than 8-12 hours at a time, this really isn't an issue. Charging is pretty quick considering the batery size, and the auto power-off after 10 mins disconnected is useful.Build Quality: It's well built / sturdy - though if you're planning to throw it in a bag, I'd jerry-rig some kind of cover / protection for the bass radiator on the rear. That's the only real weak point - the rest of the speaker seems rugged.Note: The equalizer button post-update is essentially one of the best 'bass boost' functions I've encountered - but it does muddy the sound a little bit. The speaker is still super loud & has excellent clarity when this is switched off - the bass is just less... oppressive. Treat that button as a nighclub experience, and select appropriate music accordingly!
