Meizu Hifi USB-C Headphone Adapter Review

[Saidera]

There has to be more dongles like these Meizus and Apples available across the world and not just online.

Does anyone know if this measures better from a MacBook Pro?

Does anyone know if this measures better from a MacBook Pro?

1. The PC->DUT->AP analyzer config used in this review wasn't set up properly, which resulted in increased high frequency noise, which will not be present when you use the Meizu Hifi with headphones.
You can read more about this here and here. It is an artifact of the measurement equipment, not the dongle's actual noise.

2. Here's a collection of Meizu Hifi/Hifi Pro measurements done properly: https://www.audiosciencereview.com/...b-c-phone-dongle-dac-review.10423/post-646592

Using ER2SE I'm getting much more volume out of my MacBook headphone jack than the meizu dongle. Anyone know why? I highly doubt my MacBook headphone jack outputs over 2 Vrms.

You need to trick the meizu into high impedance mode.

3.5mm to 3.5mm empty extension or adapter onto the meizu, plug into phone then plug iem into extension once recognised

what a joke. I need ANOTHER adapter to make this thing work as advertised...

 

[Sharur]

Anyone know of any similarly priced usb-c dongles that don't need to be "tricked" into high power mode?

It works exactly as advertised. With impedance sensing.

"dynamic self-adaptive adjustment" hmmm
sadly nowhere in this review was the dynamic self-adaptive adjustment "feature" mentioned

You realise this review was not, in fact, an advertisement?

 

[Sharur]

Can we all stop confusing "working as advertised" with "working as

You realise this review was not, in fact, an advertisement?

I mean, "dynamic adaptive adjustment" isn't the most self-explanatory thing in the world, is it? Your point is clear and I obviously missed the fine print. Nothing I can do about it besides return the product.

No, it is not.

But there is a growing tendency on here to confuse not working how the reader expected with not working as advertised or intended by the manufacturer.

This might be off topic, but do you know where one can buy that Ugreen dongle? There seem to be some available on aliexpress, but they look slightly different and are packaged in a plastic pouch instead of a cardboard box, so I'm not sure if they're the same model.

Back on topic tho, should I expect similar performance issues when using this dongle as DAC with a mains-powered devices, like a PC or Raspberry Pi streamer? My amplifier is powered by a double insulated Class II power supply, so I expect there shouldn't be any problems with ground loops.

here is the exact model that WolfX-700 tested: https://detail.tmall.com/item.htm?id=634513448049

What issues are you referring to exactly? The rising high frequency noise or the low output voltage?

What low output voltage? Amir's measurement show 2V, and he specifically comments on that

the conversation about that is literally two messages above mine.

I'm talking about the noise.

 

[staticV3]

I'm talking about the noise.

As long as you're not using an Audio Precision APx555 Audio Analyzer, you should not expect similar high frequency noise.

Oh, I didn't expect the problem to be so specific, lol. Thanks.

The auto impedance sensing feature it has? That's misleading to call it a low output voltage "issue." It's just a gain mode.
