Looking for laptop speakers
« on: October 10, 2020, 07:00:54 PM »

I'm looking to buy a pair of speakers for my laptop (nothing special, listening to my music while I work) and I came across with those cheap and cheerful ones: https://trust.com/en/product/21560-tytan-2-0-speaker-set

Sorry if it's a dumb question, but can someone explain to me how the USB port can provide enough power to achieve 18W ??

I'd never touch anything Trust, they've always been junk in my experience.

I got the cheap Creative Pebble v1 for my mum and they work fine from a single USB 2.0 port, despite the literature suggesting otherwise.

I've had a pair of mains powered Trust speakers for years now with no problems, OK the are not hi-fi quality but have served me OK.

I'm clearly not fussy about the quality, but how possibly my USB 2.0 port with 0.5A / 5V can provide such power ??

I was thinking I'd need an adapter like this: https://www.amazon.co.uk/UGREEN-Charger-Delivery-Compatible-Nintendo-dp-B0819KTV96/dp/B0819KTV96/ref=dp_ob_title_wld

Well you’re absolutely correct: 0.5 A at 5V cannot conjure up 18W over USB, not without a D.C. external supply?

Power in speakers has traditionally been quoted as equivalent into an 8 Ohm load, in other words the voltage supplied is measured relative to 1 = 2.83 V = √8 V equivalent to 1 W.

That's the thing, the Creative Pebble sound amazing to me and I'm an audio snob.

Yes but all mine do is play sound for the odd Facebook or Youtube video (not music) and beep or sound warnings. If I listen to music I do it with the hi-fi downstairs  ;)

Any specific Trust speakers that you've had a bad experience ?

Nothing recent so they may have improved, they just always used to be the absolute bargain basement solution to "get sound" rather than something you want to listen to for long periods.

My guess is that Trust stuff is trash, I am also very fussy about audio.  The trouble with speakers is that the cheap ones I have bought in the past have been horrible sounding.

For something small and portable the Logitech UE series of bluetooth speakers are excellent, they sound good and are really handy.  Even the smallest one sounds excellent for its size, why not grab one on Black Friday?
