If anyone could help with this issue too, would be great...

This is the iPhone forum. Post your question in the Mac forum.

Hi,

today I got my Philips AEA2500 Bluetooth Hifi Adapter (with NFC and apt-X) and I tested it with my iPhone 5, Nokia Lumia 800 und MacBook Pro Retina (Mid 2012). I works and sounds good, but in comparison to Airplay something is missing. All devices sound the same via BT. I´m shure the Lumia 800 does not support apt-x, because its to old. I also found a list of apt-x supported devices:

http://www.jessebandersen.com/2012/05/list-of-apt-x-compatible-devices.html

The Mac Books are listed as supported and iPhones, iPads, iPods and the Lumia 800 as not supported.

This Page shows how APT-X works:

It seems that in my testcases not the full bandwith is transfered to the BT Receiver, beause "something was missing" in the music, the spectrum was not filled out, no volume and a little bit flat sound against the Airplay solution. In the next Days I will get an iPhone 5S and a Lumia 920 and retest it, but I assume I will not get a better result.

If you dont know the difference, the BT sound sounds well enough. I hope I will get an officially supported APT-X devices and can here the better quality.

So my open questions are:

Does the Mac Book Pro Retina (Mid 2012) really support APT-X?

Why I didn´t hear a difference between MacBook and iPhone, if the Mac Book really supports aptX?

Does it really sound better than without aptX or same like Airplay?

My Test Equipment:

Denon x2000 AV Receiver (Airplay support, PURE Sound Mode, without enabled Equalizer Opt.)

Canton Chrono SL Speakers

Philips AEA2500 BT Hifi Adapter (aptX certified)

Apple iPhone 5

Apple Macbook Pro Retina (Mid 2012, OSX 10.9.3)

Nokia Lumia 800

Spotify Music Player with extreme quality streaming (320kbits/s vbr)

Addition:

based on https://discussions.apple.com/thread/3891328?start=0&tstart=0

I logged the Bluetooth Audio at Mac OSX (now 10.9.3) and I got successfully connected BT Audio with aptX

Mon Jun  2 13:31:56 201 [bluetoothaudiod:28072] AVStreamConfiguration.m:2917 [parse] +media codec: AptX

Mon Jun  2 13:31:56 201 [bluetoothaudiod:28072] BluetoothAudio.m:720 [autoConfig AptX]

Mon Jun  2 13:31:56 201 [bluetoothaudiod:28072] AVStreamEndpoint.m:1461 [setCodec] AptXCodec

Mon Jun  2 13:31:56 201 [bluetoothaudiod:28072] AVStreamConfiguration.m:2640 [getData]- Found: AptX codec

So with this I assume aptX is working on my Macbook Pro Retina. But I hear no difference to my iPhone BT connection and I tried it many times. The does not mean the BT Connections sounds bad it is really good, but not as good as airplay. My conclusion for now is, aptX is a nice marketing issue but not a High Fidelity feature or Airplay killer. Maybe with Headphones you can hear a difference, but with my equipment, which is high level, I can´t hear a real difference between aptX enabled (on MBPR) or disabled (iPhone5, Lumia800)

So if you are not using Airplay, this BT device combination is a good choise, even if aptX is enabled or not.

Interesting analysis. Thanks!

Although it probably belongs in the Mac forums.

Apple is about money and not music quality. I own an iPhone 6 plus but my main music device is my lovely Samsung Note 4 as it supports Aptx. I respect Samsung not going cheap and are paying to include such cool technology in their devices Since many years. The music streaming in my car through Note 4 is amazing. Thanks Samsung and Aptx and bad Apple.

Samsung bought the CSR years ago.

maybe that's why apple doesn't go for the APT-X.

apple is still hanging on to AAC.

Samsung never owned the part of CSR which licenses Aptx (they had a 5% stake in that part of the company) but in any case they sold their entire holdings in CSR in 2014. I'm very sceptical that your car hifi can discriminate Aptx Bluetooth from regular Bluetooth as Aptx is really geared to audiophile equipment, not car stereo no matter how loud your car amp or speakers can play.

iOS devices use A2DP which avoids CSR royalties but otherwise similar if the receiving device is of sufficient quality. More here http://www.head-fi.org/t/601665/what-are-head-fi-members-views-on-apt-x-lossless -codec-over-bluetooth/165#post_11401344

i don't agree with your comment that Apple is about profit and not music quality but have no interest in arguing the point with you.

In my post above I should have written that iOS devices use a special extension to the A2DP protocol which uses high quality AAC codec to get similar quality to Aptx without paying royalties. Like aptx the receiving unit has to be compatible with this extension.
