    High End Bluetooth Headphones

    I just want to update y'all on this. Avantree never sent the new Priva to test.  Said that they will be delayed due to problems with the new unit still.  So I don't know if they really are going to send me a new unit to test or if they were just trying to give a good PR image. Looks like they...

    What are head-fi members views on apt-x lossless codec (over bluetooth)?

    As far as I have experienced with my MDR-1RBTMK2 AptX connection sounds smoother than non-AptX connections. I don't think it will make a difference in the amount of bass response you hear with AptX vs SBC connection. When I first got the headphones I thought I heard more of a mid-bass hump when...

    Possibly fake Sony 7509HD - but how do I tell?

    I've thought about that idea many times! But I feel bad about the $200+ USD that I wasted on them lost!   I may one day try putting the dampening mod in place to see if it would diminish some of that midrange peak. However, I don't think covering that vent up would increase the bass, it most...

    Possibly fake Sony 7509HD - but how do I tell?

    Actually I believe I had really broken these headphones in a long time ago as I said.  I ran them for hours and hours on end with all kinds of loud music (bass, midrange and treble) and even ran my pink noise and white noise tests through them. It's not that they sound horrible. Just that I was...

    High End Bluetooth Headphones

    Phoebe at Avantree said she is arranging to send me a new updated Priva to test. I have no idea how long it will take for them to send it to me. But I am looking forward to it to see how it compares with what I've already tried and tested. You are right about Avantree support, they really do...

    What are head-fi members views on apt-x lossless codec (over bluetooth)?

    I tested between the 2 modes (Standared and AptX) with the Sony MDR-1RBTMK2 just now connected to my AZIO Bluetooth 4.0 AptX USB adapter plugged into my Samsung high end gamer laptop and I can confirm that in AptX mode the audio sound is smoother sounding than when in regular Standard SBC codec...

    High End Bluetooth Headphones

    I hear slight difference on quick comparing the sound when paired with AptX and with SBC codec mode. They both sound really good on these Sony MDR-1RBTMK2 headphones. But I can clearly hear that when it is connected in AptX mode the audio is a bit cleaner and smoother sounding. The SBC mode is...

    High End Bluetooth Headphones

    I've already tried that connecting to my laptop using the AZIO USB Bluetooth AptX adapter and yes putting the Sony MBR-1RBTMK2 into the Standard mode and connecting to the laptop, CSR AptX Logo does not pop up. As for the Priva, I don't have it anymore as I said earlier, I have returned it. As...

    High End Bluetooth Headphones

    Avantree support rep responded to my email last evening saying that they will escalate my issue concern to their developers and also said she would like me to test out an updated version of the Priva for free. I was impressed with the response.  But after I said I would accept the offer to test...

    Sony MDR-1R series MK2

    Okay, I suppose then that since it could be in A2DP mode with the LED blink 2x interval, then it could be using the AptX codec mode too. So maybe it's okay. But I want to confirm that the Sony is really indeed using the AptX codec during this 2x blinking mode.  There is no way to do that I guess.

    Sony MDR-1R series MK2

    From the Sony English documentation I see, they provide a chart showing what the blinking LED status lights represent. They don't specifically mention AptX mode but rather specify or describe the mode that AptX is supposed to be enabled and working as "Playing music or During a call (Connected...

    High End Bluetooth Headphones

    I suspect that the Avantree Priva and the Miccus TX4 are using the same chipset and software/firmware and that's why they both exhibit this bug. I use the CSR based AZIO Bluetooth AptX USB dongle and also the similar SuperTech Bluetooth AptX USB dongle on my Windows 8.1 Pro 64 bit PC's and the...

    Sony MDR-1R series MK2

    Question for those of you that have the MDR1RBTMK2 headphones and either of these standalone Bluetooth AptX transmitters: Avantree Priva or the Miccus TX4. I have these transmitters and noticed a strange symptom of concern to me when connecting and pairing my headphones to these transmitters in...

    High End Bluetooth Headphones

    Hello, I recently bought a new set of Sony MDR1RBTMK2 headphones and bought several Bluetooth transmitters and USB dongles to enable my PC's to transmit AptX mode to the Sony headphones. The Sony headphones are great and have a nice LED status light that tells you what mode it is connected and...

    What are head-fi members views on apt-x lossless codec (over bluetooth)?

        Thanks for confirmation replies, but the default setting was already set to the CSR Bluetooth Audio Renderer it seems.  But I found out why the CSR Bluetooth stack sounded thin and weak compared to playing same music files through the 3.5mm headphone jack connection. My Samsung laptop...
