The connection to the PC / Smartphone is relatively simple:
1. Bluetooth Unignore 2. button on the adapter 3. Press the Bluetooth pairing from the PC to enable 4. 5. "PhilipsBT" is recognized as a speaker and the sound is transmitted immediately.
From now on, the connection is added automatically when your Bluetooth enabled (press the button if necessary if the source device changes).
I found the sound via Bluetooth satisfactory. Something mushy, a little quieter, but acceptable. Just for fun I have the adapter with headphones tested (Creative Aurvana Live). Is unfortunately much too quiet despite maximum volume. With the Z523 it's thanks enough SPL capability with the volume all right. But apart from that I wanted other speakers, because the satellites are quite weak and the subwoofer has an unbearable hum loop. So I have a few Heco Victa 301 found me. Plus one from China SMSL SA-50 Class T amplifier (arrived today). Transition, I have the LS connected to an ancient Sony TA-F161 amplifier. That was a significant improvement. And here you can hear the difference between Bluetooth and cable but out even more clearly. The audio quality via conventional Bluetooth is just not good.
APTX was needed and for that I needed a USB receiver with APTX. I initially wanted to also here an expensive Sennheiser Creative or buy (selection is not yet large) to make it work with security. Because I have Windows 8.1 and, according to some misleading sources on the Internet to CSR Harmony not be compatible with Windows 8. I have yet decided to approve of BT0015 Logilink to buy because of the price of less than 7 euros a test does not hurt so much. Gold Right! I have my internal Bluetooth chip disabled in Device Manager, installed receiver to a USB port and the included CSR Harmony, reboot. Ensures that the CSR Bluetooth character always in the taskbar (recommended but not required).
1. Again button on the receiver, press 2. Right-click the CSR Bluetooth icon 3. Add Bluetooth Device -> Audio / Video 4. PhilipsBT select finished. Now a notification should appear that a APTX device was connected.
My impression: Auweia, Wow. First volume level turn down. Curiously, it is loud with me than with cable! No porridge, super volume. Clear, punchy, dynamic music at 320Kbps MP3 and Flac files. Clear in Flac the transmission speed with the APTX codec should not just work, but added so well my ears are not there to detect a significant difference.
Finally, the adapter itself: processing is clean. The adapter is not as noble, as in the pictures. Very discreet. The plastic housing is very cheap due to its light weight, but it is stable, does not give in to pressure. The delivery is still a short RCA to jack cable. The contacts are not gilded.
Power consumption is a maximum of 1 watt, perhaps even dadrunter. By the way: According to the ammeter I consume with Ultrabook, wireless router, Class T amplifier and Adapter just 12-14 watts. With the Logitech sound system is 24 watts.
APTX must be known! It's worth it easy.
Supplement with respect to the auto connection: actually works (Smartphone), but sometimes sporadically in Windows. When restarting the connection is not established immediately. You have to double on Bluetooth icon. Then PhilippsBT, then A2DP and you are connected. Is not a huge drawback, but certainly worth a info.
In addition, an information value. In films the picture and sound are quite in sync. In an Audio Delay test I could find no delay. In some very fast talking but a delay of about 25ms is noticeable.
Subsequent comparison Xonar DSX:
The adapter for Windows, a sound card. The sound quality is comparable with older Realtek chips. The Realtec ALC892 is better. A Xonar DSX course more clearly.
