How a "10 Watt" Bluetooth speaker suddenly becomes a 3 Watt Bluetooth speaker :)

Just interested in others' opinions on this, as to me this is a clear case of fraud, but maybe I'm overreacting a bit as usual :)

I was looking casually for a cheap Bluetooth speaker for the kitchen and ordered this:

https://www.amazon.co.uk/dp/B07MYQZGZJ

Seemed like a good deal! Good reviews, 10 Watts "sounded" like a lot, and price looked good too, so went ahead.

When I got the package, the whole thing sounded a bit tinny for 10 Watts, and I got a bit wary about it.

I have a background in electronics, so I opened the thing up and found this:



Bottom line: While you could theorize that the 3W speaker could simply be overdriven with a 10 Watt amplifier chip so the whole thing could still get a "pass", no amount of magic can turn a 3 Watt amplifier chip into a 10 W amplifier chip. The chip is rated at 3 W into 4 Ohms at 5 V (which is also the maximum permissible supply voltage).

Am I being over-critical? :)

  • The description clearly says fitted with 10W drivers.....that speaker definitely says 3W
    Multiple units are linkable...so perhap syou need to buy 3 and 1/3 of them to get the full 10W experience :D
    Not sure you'll still get it having opened the thing, but it says 60 day money back guarantee.

    :) Yeah, the issue is not so much about returning it or the money... it's just a bit disturbing that there seems to be widespread false information in audio product descriptions.

    What doesn't help either is that I submitted a critical review (fully objective, just stating the facts that I stated in this post), which got kindly rejected by Amazon for not adhering to their "review guidelines".

    I mean, do they passively defend false product information?

    Maybe onto something here, leave it in half, encase each half in resin...sign it Hurst....you could make millions, just don't sell it on amazon, so they can't make anything out of it :D

  • Are we talking Watts, Watts RMS, Watts Medium, Watts PP, Watts PMPO, Watts DIN?

    It's a little bit the jungle here and most probably your 10 Watts are a selling argument that corresponds to...nothing trustable

  • Companies generally lie about specs, laptop battery life being a classic example. Good thing about Amazon, it is relatively easy to return stuff

  • “10 watt driver” typically is a spec of a speaker not an amp. It doesn’t mention amplifier power anywhere that I can see. Misleading but I don’t think it’s technically wrong.

    No, you aren't being over-critical.Return it and get your money back and write a bad review.

    FWIW, it seems that with bluetooth speakers really cheap ones tend to sound really cheap.

    Look at the photo of the speaker! It as well is only rated for 3 Watts, so they're definitely in trouble here 😉

    The datasheet says "average power" I think, so that would be RMS.

    Needless to say though that PMPO in particular is a totally meaningless figure. You could state "9999999999999 Gigawatts PMPO" and still technically be right.

    I keep hearing about "consumer rights" and "protection" all the time in recent years to the point of being outright annoying. Yet stuff like "PMPO" is not illegal. A bit odd!

    :D missed that! Curious how they came up with 10 watts. They couldn’t be lying could they?? ;)

    Pretty outrageous of Amazon (assuming you didn’t use a naughty word or libel anyone). I’d return the thing.

    Also, don’t you have a govt agency that regulates false claims in commerce? I’d file with them.

    I think you got what you were looking for (unfortunately, both casual and cheap and all that comes with that). But yes its a huge bummer when things are not what they claim to be.

    In that size range, my favorite device is the Sony SRS speakers. I have the older model SRS -X3, its small but claims 20W and sounds MASSIVE for its very small size. In my mind, its worth paying in the £40- £60 if you find a good product.

  • You get what you pay for.

    My Jbl xtreme has been good to me. Can power an SH-101 & interface off it for a few hours.

    Nothing passive about that. It's very active, if you ask me.

    Am interested because of eBay, bought fake shure headphones with no comeback because of the timeframe, I realised too late, I said it was criminal activity, they were not interested

    No naughty words and no libel, but I was slightly pissed indeed because if there's one thing in the world that I insist on, it's honesty. The review was completely factual and "unemotional" though and included the above photos.

    Thanks for the recommendation. Yes, I'm aware that at that price point, I can't expect a lot. But it's more generally about the lies. I just don't like them. Even if you buy a $7000 Dacia, you expect it to have 90 HP if the dealership says 90 HP. Not 30. :)

    :) There was a time (I think this has abated a bit) when some "clever" marketing chap introduced the aforementioned "PMPO" "rating", which is supposed to mean "Peak Momentary Power Output". As "momentary" can also mean 0.000000000001 nanoseconds, the figure is completely nonsensical and -- it was just hilarious. You would find speakers the size of a credit card, and they said "1000 Watts PMPO" in the product description.

    I mean, how can anything like that "survive" in any legal system? It's like selling a car with "1000000000000 EHP" (Explosive Horse Power -- only available when you plant a bomb in each cylinder).

    No specifics, i.e. no reference to which particular rule was broken. But it seems to be a widespread problem, there's even "specialized" sites that publish reviews about fraudulent products because Amazon, eBay etc. refused to.

    I think this is a dangerous situation. Shops and malls are dying all over the place, and Amazon and eBay essentially have a monopoly on "general purpose" online shopping now. If they do not care about identifying and removing misleading or outright wrong product information, then we're in trouble!

    I'd try again with the review and also email Amazon (though i seem to recall that it is really hard to find the link to contact them) about the false advertising. False advertising by people selling on Amazon is rampant. :(

  • @SevenSystems
    You really cared about the wattage number when buying a loudspeaker?
    Shame on you :#
    Wattage is about as informative as the word "Pro" in a product.
    Sometimes it's more like a warning and a good reason to have a closer look.

    The only useful database of Bluetooth speakers is this one.

    http://switcher.oluvsgadgets.net/

    Unfortunately it's not maintained anymore and it doesn't contain more recent products.

    Using this genius utility, I've ordered the five best ones (from my very subjective ear) and compared them at home. And I've learned that what I really want is a BT speaker that provides relatively transparent sound with a fairly hefty bass boost when listening to it at low levels. Loudness EQ so to say. Those battery-powered, lightweight speakers won't usually move your belly anyway.

  • Why to buy unindentified chinese speaker. The good speakers are so cheap now. I bought ue boom2 a week ago for 70 usd. I think its cheap for a speaker that i know for sure will be top notch, 2 years warranty, waterproof.

    @rs2000 hah, that's truly an amazing tool. That's the times when I actually miss the real studio with the literally several cubic meters of foam blocks (the studio was literally totally dead through the ENTIRE frequency range!), and my old trusty Tannoy 800As 🙂

    (the photo shows a slightly chaotic era that includes a printer and an old Behringer MX8000 as "decoration" 😂)

    Nice!
    I love the "dead" sound when entering the studio. And the smell :D
    Right, it wouldn't look professional without the mixing desk.
    Is that the one in which Behringer even copied (snitched?) the Soundcraft logo on one of the PCBs?

  • My last info was that it's actually a Mackie ripoff? 😆 whatever. It was surprisingly good, very low noise, not a lot of "scratching" when moving pots or faders, and the EQs sounded absolutely amazing when overdriven! Leaves every "analog smoothness tube simulation overdrive" AU in the dust!

    Yep the smell was very characteristic. My then-gf hugged and sniffed one of the "walls" each time she visited me and said she's on drugs now 😎

    And the "deadness", yeah. You could feel it instantly when entering the room. Unreal. Like entering another dimension. And great for mixing the bottom end. I had fought with muddy bass monitoring and resonances / standing waves etc. for years before that so I went all-in this time 😁
