Hi Charlie,

Great question!

I would like to know the answer myself. It is my understanding that Bluetooth is simply transferring data packets. My music files are CD quality or better lossless FLAC files. So, I presume that I am hearing CD quality sound in the headphones so long as the transfer rates and buffering do not impose any limitations or interruptions.

Is there a way to measure the data rate or other characteristics to confirm the quality of the transfer?

Best,

Art

I hunted around a little, and it looks like Bluetooth 3.0 can handle the speeds necessary to transfer flac files. Here's a headline from a web page in 2009: Bluetooth 3.0 goes to 24 Mbps via 802.11.

24 Mbps is plenty fast enough to transfer CD quality. 16 bit, 44.1 kHz, 2 channel translates to around 1.4 Mbps.

I think that if you're listening to CD quality files (flac or whatever), you're probably getting the real thing.

I don't know how to measure the throughput, but the math seems to show you've got the speed you need.

Hey Art,
And the advantage of Bluetooth, Wireless is???? You can walk more when listening?????
How far?????
I really don't "get" it. Never one time felt like my "wire" was a disadvantage in any case.
I googled them, they don't look as good as the 125s, but perhaps your 125s being older technology, maybe they have made improvements?????
Anyway, happy listening,
God Bless,
Wayne
God bless the child that's got his own.

Charlie,

Thanks for your research. Your findings appear to agree with what my son-in-law has told me (he is a highly-experienced senior level software developer).

Wayne,

To answer your comments:

I am not losing any fidelity, compared to my wired Grado phones. Yes, wires do bother me - to the point where I seldom used my earphones unless I was traveling or otherwise unable to listen to my system. I can move around with the Bluetooth phones - probably as much as 30 feet depending upon room configuration. But, mobility is not my primary concern. I really dislike wires dangling from earphones, so I was very excited to learn about the Grado Wireless phones.

Grado does not claim that the Wireless phones equal the SR125s. And, perhaps they do not match the newer SR125s. However, I cannot tell much, if any, difference between my SR125s and my Grado Wireless phones.

No phones that I have heard match my system sound, so that was not my expectation. I am pleased with my Grado Wireless phones. They will do very nicely when I am in a remote listening situation.

Best to you both,

Art

A bit of a departure from "noise cancelling"......

I've just today placed an order for Audeze LCD-X (creator package) :)

I have good reason to believe this choice would be met by nothing other than positive feedback from the forum members. Also, in addition to the moderators response to my question about the possibility of GE headphones, I have input from other sources that would lead me to believe it is unlikely that GE will be introducing headphones in the near (1 year) future.

I’ve been a fan of audeze since the lcd-2. The x and xc are fantastic - listened to them via a chord hugo2. These headphones are very articulate, have good bass depth & texture, and are certainly a great alternative if you can’t listen to your triton towers. Good call.
