With contender from sword like Sony , JBL , Soundcore , LG and others , Sharp has its work cut out to be the belle of the musket ball . Let ’s get this party ( loudspeaker ) bulge out .
Design
Despite rather modest proportions for a party speaker system , the PS-921(BK ) is design to be seen as well as take heed with red accents , peck of signature Sharp stigmatization , and large rubberised buttons go bad up the ocean of Black person .
A 50:50 mix of rugged credit card and metal front grille , it ’s a rotund lump featuring threefold two - inch driver and a very visible four - column inch subwoofer that faces you in a gargoyle - comparable mode . Atop the back you ’ll find a carry handle for portability , which unfortunately does a fine job of cut into your finger joints .
That said , weighing just 2.7 kg and resonant of an authority - sized instant coffee tin , the PS-921(BK ) is every bit as portable as Sharp make out , and easily transportable from room - to - room , patio to syndicate , beach to barroom , or hotel suite to hot bathing tub … if that ’s how you pick out to populate your life .
The majority of the top shell is reserved for the aforementioned array of control buttons catering for everything from source , play / pause , Bluetooth pairing and skip to volume , 3D / sea bass , and inflammation effects . With no companion app in muckle , you ’ll get accustomed to these very cursorily .
flank the bottom curvature of the ascendance panel is a line of multicolour LEDs denoting everything from source pick to volume level and bass mode , but the shed light on experience volunteer by the PS-921(BK ) does n’t end there .
Hit the lightbulb clitoris and its company objet d’art result issue kick into gear , circumnavigating the subwoofer in a uninterrupted multicolour ring and complement by a streak of erose bright ashen light on either side . More on Sharp ’s discotheque inferno a little later .
gyrate the PS-921(BK ) around and hidden behind a smutty orthogonal rubber panel , you ’ll find access to a USB port for flash drive content , a 3.5 mm aux port , and a larboard for main charging . Located dead centre underneath the unit of measurement is an M6 gaoler thread work up into the alkali for stand or wall square bracket mounting .
An IPX5 rating mean its water supply resistant if not waterproof . By all means take it to the puddle and stead by the hot tub , just do n’t await it to survive if it hang in
Features
The PS-921(BK ) is a glower and a shower , with its full spectrum ignition consequence make the speaker ’s company firearm . Give the lightbulb button a short press to motorcycle through a multi - coloured swap shop of sequence that illuminate the ring around the subwoofer .
Choose from a rainbow spectrum , colouration revolve flashing , gradual colour pulsing , or a colour equaliser effect . A two - arcsecond pressure activates satisfying or flashing white side light-emitting diode to make out the short show . A four - second press switches everything off and allows your dopamine levels to stabilize .
Whether you want a disco show will depend on your temper and the occasion . In accuracy , it ’s always going to be Marmite but if you ’ve decided to buy a party speaker unit , the odds are that lighting effects play a big part in your decision and to that end , the PS-921(BK ) performs admirably .

The big kicker here is no fellow app . While the plug and dally nature of the PS-921(BK ) offers beautiful simpleness for Bluetooth pairing and teem songs , it ’s a hindrance when the lighting issue ca n’t be ascertain remotely from a phone and only on the speaker unit itself .
Time for a little bit of bass part and a minuscule bit of space . The PS-921(BK ) has a low - end theory when it come to frequencies and takes a thrust at spatial sound recording thanks to the 3D / Bass feature film .
Toggle between Bass Off , 3D Off ; Bass Off , 3D On ; Bass On , 3D Off ; and Bass On , 3D On . Take your time to experiment here before finding the Goldilocks coiffe to please your earholes , and you may need to mess about with your root gimmick EQ configurations as well — commend , no companion app .
The PS-921(BK ) loves to deliver belly rumbles and if that ’s your affair , we ’d warmly recommend Bass persist on at all time .
spacial audio , however , is notoriously toilsome to put through efficaciously in any iteration , but on a speaker system barren of 360 - arcdegree sound it ’s even more ambitious because the technology relies on create the perception of audio coming from various direction .
What ’s odd here , is that you have a spherical speaker with the double-dyed bod factor to present an immersive , spherical 3D soundstage , but you ’re hamstrung by front - facing driver only . swash about the lineament to your friends in the saloon , just do n’t require it to strike at the after party .
Arguably better at delivering a large soundstage is Sharp ’s Duo Mode — the choice to add a 2nd PS-921(BK ) via Bluetooth for True Wireless Stereo with a left over and right channel .
I ’m yet to test this feature , but the estimation of a wider , stereophonic soundstage with double the bass sounds like a winner where entertaining is concerned . When brook or wall - go up , I ’d ideate you would have a fairly formidable and undeniably low-priced party PA on your hands .
Connectivity
For reasons unknown , the PS-921(BK ) makes a unusual didgeridoo audio when you switch it on , followed by a spoken Scripture source selection in a manful American accent . identicalness crisis aside , it ’s fun , clear , concise and instant .
The same goes for every aspect of the loudspeaker system ’s setup and performance — a toddler could surmount it in minute , Bluetooth pairingtakes msec , and the muscularity memory for flicking through inflammation or 3D / Bass options quickly becomes embedded . Great for getting the company started .
A note on germ options . While it would be great — for DJ accountant especially — to have an RCA input , an aux in for devices and a USB port for flash drive full of air ( 32 GB soap capacity ) is a seemly pick and provides unanimous alternatives to Bluetooth .

However , while plugging in a instant drive automatically trifle its contents , there ’s no way of selecting playlists or song away from blindly skipping tracks . If shuffling toothed wheel fathom like fun , then great . If you ’re worried your Jive Bunny back catalogue will put up its ugly head , it ’s well avoided .
The USB port doubles as a charger for nomadic equipment , but you ’ll still postulate to use Bluetooth to wreak content from it .
Battery life
Great for after party , not so much for all day rave . The PS-921(BK ) offer a fairly mediocre 14 hours of playday between charges and that ’s if you keep the disco lights off and do n’t use the USB port to charge your equipment .
Get your glow on to enhance the party atmosphere , and you may expect to shave important time off that total as the lighting effect always pull in extra power from the build - in rechargeable lithium - ion electric battery .
It ’s unmanageable to give a quantifiable number here owe to other factors such as volume tier , lighting style intensity , and exercise patterns , but you could potentially be looking at a few minute if going with always - on as contradict to an audio - only operation .
Of course , if you happen to be near a mogul level , punch into main mightiness allows for continuous use of both sound and light while recharge the battery , which takes circa three 60 minutes from matted to full .
Sound Quality
As a party speaker with booming bass voice that wo n’t get muddy at max volume , the Sharp PS-921(BK ) offers plenty of bang for your Pearl Sydenstricker Buck , and the overall sound lineament is on the ripe side of chip .
If Classic Unwind on BBC Radio 3 is your go - to , do n’t await the most mature or balanced sound . shade and relative frequency separation are not ideas this speaker is unforced to flirt with , but then it never claim to be a boon for mindfulness .
Ennio Morricone ’s iconic L’estasi dell’oro comes across as a bit of a mussiness and lacks wallop without a true stereo soundstage , but emerge unharmed into boom bap hip hop and the PS-921(BK ) starts to make sense .
This is a political party speaker , after all , and so the big basso , forceful kick drum , and clear , distinct vocals of Kendrick Lamar ’s GNX ( via Apple Music ) do n’t let down . The same run for Mandingo by Wu - Tang Clan and a tear of leaping - inducing Boiled Peanuts by Doechii .
With three-D and Bass both on , the hearing experience was pretty mystifying . Turn three-D off and keep the Bass on and we recall you ’ll find your happy shoes with the expert balance of bass - profound lols and overall audio lucidity .
The relative complexity of Scrambled Eggs by Moonchild Sanelly , Blu DeTiger ’s cover of Murder On The Dancefloor and Lexa Gates ’ Lately , Nothing are handled in impressive - enough fashion , while Deep Dish ’s remix of Madonna ’s Music proves this is a talker secure to go firmly when call upon .

Should you buy it?
Get the heavy options in good order and the PS-921(BK ) is a party loudspeaker system willing to please for a pocket-sized outgo . Lighting force enhance the experience , while its plug - and - play nature ensures the party will get underway without delay .
ordinarily no app means beautiful simplicity , but here it feels lacking if you want to see the kindling effects . Battery life is mid at expert , while the addition of 3D spatial audio fail to deliver . As fun as newsflash driving force roulette voice , we ’d love more control over the subject matter .
Final Thoughts
The PS-921(BK ) is an ambitious attempt at a feature - packed political party talker , with change back from £ 150 , but it ’s not without its contradictions .
Go crazy with the lighting , and your battery living will take a incision . Brag about the 3D spatial audio recording and you ’ll overpromise while it underdelivers . Revel in the dead sluttish control then deplore the lack of a companion app .
That articulate , I had fun hanging out and once comfortable with its limitations , while focalize on its potent suit , we ’d have no scruple in let this thing loose on any unsuspecting party guests .
Competition in this area is blind drunk to say the least , and if you feel company lights are an extravagance you’re able to do without , there are plenty ofBest Bluetooth SpeakersandBest Outdoor SpeakersI’d recommend .
If disco music lights are a requirement and the budget will stretch out further , you could seem at something like theSony SRS - XP700 … although or else maybe buy two acute loudspeaker and strike up Duo Mode for that wider , stereophonic soundstage .
