Westinghouse washing machines are next with some ultra sonic buds.This market (headphones and earbuds) is HUGE. Wonder what company will come in next? Think the images (and on The Verge) look good, interested to read the reviews but for now happy with my Sennheiser M4s.
Yeah, one of the reasons I will never buy a Dyson product.Just a shame that dyson campaigned for the UK to leave the EU and then moved to singapore. Also they ugly.
Buy a Mustang and get some free Mustang Music buds….😂Westinghouse washing machines are next with some ultra sonic buds.
And also recently announced that they are cutting about 1,000 UK jobs.Just a shame that dyson campaigned for the UK to leave the EU and then moved to singapore. Also they ugly.
Get a Miele, if you hoover upstairs, you’ll find it will hoover downstairs as well. Much better product reliability.Agreed. Look at any other vacuum's debris container after you vacuum, especially on carpet, and compare it to the debris container after you vacuum with a Dyson. The difference has always been night and day, Dyson destroys the competition.
I've never had an issue with reliability from Dyson, but unlike a lot of people in here, I am open to try new products. Thanks for the recommendation.Get a Miele, if you hoover upstairs, you’ll find it will hoover downstairs as well. Much better product reliability.
Miele are the best for Washers, Dryers, and hoovers.I've never had an issue with reliability from Dyson, but unlike a lot of people in here, I am open to try new products. Thanks for the recommendation.
I am no acoustic engineer, so correct me if I am wrong:
Human hearing typically picks up sounds between 20Hz and 20.000Hz. I am not even sure that Bluetooth and compressed audio formats can faithfully reproduce sounds throughout that range, but let us suppose they could. Why one earth are these headphones sampling at 384,000Hz for active noise cancellation? Generally when measuring continuous quantities like sound levels, one oversamples at 2 or 3 times the highest rate you are interested in to avoid aliasing. For active noise cancellation I assume this would be 40,000Hz or possibly 60,000Hz. Is there any real advantage to sampling at 384,000Hz?
Sorry if I am being obtuse, but this 384kHz number sounds a little like the volume dial on the guitar in the movie Spinal Tap that goes up 11, or the old electronics shops that used to scam consumers by using a stereo system's wattage as a measure of performance.
Makes sense to me, but then again I am a mere mortal and no engineer. Mind you, the headphones could have a buffer and delay the sound received by Bluetooth to match the lag in the active noise cancellation system. Anyway, this just seems like overkill to me.I'm not a sound engineer either, but you've raised an interesting question that's got me thinking.
I believe that noise cancelling works by creating an out-of-phase version of the noise which cancels out the external noise, since a signal and the equivalent out-of-phase signal cancel each other). In order to do this, the out-of-phase noise needs to be played at exactly the same time as the noise. If it's slightly delayed, then it won't cancel completely. This may be why Dyson is using such a high sampling rate for the noise.
both correct (@wyrdness). In fact, bluetooth headphones are primarily buffer. Adequate forms of RAM are dirt cheap. Constant microwaves are not great right up in your skull holes. So the compromise has always been to buffer a batch of content at best effort, while microprocessor and pre-amp take microseconds to fiddle audio enhancements and separate noise+cancellation, so your audio content isn't ruined. Then the headphones keep up the struggle to collect the next buffer, fiddle, buffer, fiddle, buffer fiddle...Makes sense to me, but then again I am a mere mortal and no engineer.

I'm guessing you all who have mentioned Miele are from across the pond, because in America we don't call vacuums hoovers, unless they are a Hoover brand vacuum. Never heard of Miele, except my middle school librarian, Mrs. Miele.Miele are the best for Washers, Dryers, and hoovers.
Much obliged for the information. Now it makes sense.both correct (@wyrdness). In fact, bluetooth headphones are primarily buffer. Adequate forms of RAM are dirt cheap.

Noise cancelation is only partly reactive. It's also heavily sampling and rephase. It's a statistical game. A few microseconds of steady jet engine, human speech, air conditioning, road noise is easy to sample and replay on a loop, 180 degrees out of phase. Earphones don't always LISTEN+REACT; they conserve power by switching to SAMPLE+PREDICT. These systems system don't do well with unpredictable, sudden, or sharp noise.
You can really tell how bluetooth sucks for real-time streaming during movies, phone/conference calls. Real-time reactivity require way more power and needs a clearer signal path. Often, packet loss and workload make synch fall apart, and then device and earphones have to renegotiate to restart. This is especially noticeable in "true-wireless" earbuds when right and left get out of whack. That's the choppiness, clicks, buzzing and drops you hear (and others hear from you) on phone/conference calls; earphones CAN'T buffer, sample and counter-phase in true realtime - when they try, you pick up on it it sounds awful.
The higher sampling rate means noise cancellation can counter more of the worlds unpredictable noise, including all the gross meat-bag noises from inside your skull (breathing, heartbeat, bloodrush, blinking, swallowing, neck bones creaking, etc.). THIS is the difference between $50 ANC earphones in Walgreens, and $300+ ANC earphones from premium brands: RAM for buffering. Microphones and microprocessors for sampling. Microprocessors for DAC (digital analog converter). Power for all the chips. More power for big driver amps. And software to tie it all together.
And yet as both these and AirPods are wireless and therefore don't support lossless sound, they perform worse than most sets of $50 wired headphones. Expensive fashion accessories, not serious headphones.
