      @Andrew Wei - Thank you for asking. EarStudio is using Bluetooth 4.2, as 5.0 is not related with the audio performance. BT version has nothing to do with the audio application using A2DP (Advanced Audio Distribution Profile) because audio streaming through A2DP always goes with Bluetooth BR/EDR classic.
      It does make sense that vendors put the BT version as a significant advantage only if their products are not audio applications but just wearable devices like Fitbit dealing with arbitrary data over Bluetooth BLE and/or the upgrade version of BLE that is BT v5.0. However, BT audio does NOT use any resources of the new features, but just use the classic wireless link, that is BR/EDR.
      To sum up, please note that BT v5.0 in an audio application has no merit. Thank you.

      @Rich Shipley - I'm afraid three weeks of timeline is too risky. Do you have any address in Mexico that we can send EarStudio to?

      Hi Creator,
      I am not sure if someone asked already but is this suitable to watch a movie or tv?
      what is the Audio latency?
      will it have a aptx low latency mode?
      thanks

      안녕하세요, 주소 업데이트 요청 메일 보고 문의드립니다. 제가 survey link랑 confirmation 내용이 들어있는 메일을 삭제한 것 같아서 주소를 어떻게 적었는지 체크할 수가 없네요. 어떻게 확인할 수 있을까요?

      I will be leaving for Mexico in 3 weeks, and will be gone for 5 months. Any chance I'll get this before I leave? Otherwise I probably won't get it at all. Thanks, Rich

      @Andrew Wei - Thank you for asking. CSR8675 in EarStudio handles both Bluetooth and USB DAC. There's no other ICs other than CSR8675 and DAC. As you pointed out, CSR8675 USB DAC functionality has 16-bit/48KHz limitation. However, we believe that it is the best trade-off for its cost, size, and power consumption. Furthermore, in order to have every H/W resources fully utilized, Digital Signal Processor in CSR8675 reproduces the incoming 16-bits PCM over USB into the 24-bit outgoing PCM to DAC. Thank you.

      @vamsi Jammula - Unfortunately, the backerkit survey is not closed. Color change is not possible. Thank you.

      @Kenny Low - unfortunately, the backerkit survey is now closed. On our indiegogo campaign, 2.5mm MMCX cable add-on is still available, when you purchase another EarStudio. Thank you. LINK: https://igg.me/at/earstudio/x/17078593

      I only just realised that even in usb dac mode it only supports up to 16 bit... But why???? Why not 24 bit so it can also be used as an audiophile usb dac? What's the point of having such a good dac but not being able to go to 24 bit?!

      Simple question, what is the life span of the battery? and can it be changed? Amir

      @Paulus of Sinae - there is no noise cancellation algorithm running on EarStudio, but recent mobile phones have its own NC feature running along with EarStudio.
      As another key feature related to voice call quality, EarStudio provides precise microphone gain adjustment option to be controlled with the mobile application. We've been continuously running field tests in relation to the actual calling/receiving, we guarantee excellent voice-call quality with EarStudio. Thanks!

    28. Paulus of Sinae on

      Is there any noise cancellation with this device?

    29. Radsone Creator on

      @Arun Raja - Unfortunately, EarStudio does not support cVc noise cancellation technology from Qualcomm, in order to remain in the reasonable price range. As Qualcomm's cVc is mainly designed for Echo Cancellation and Noise Reduction, unless otherwise you connect EarStudio into a specific loudspeaker or car stereo, we assure you excellent voice-call quality with EarStudio. Thanks!

      @Edmund, @ronald johnson, @Steven Hill, @Zee DeDerp, @P.Frei - Starting from the end of October, selected customers with existing Radsone account will receiver EarStudio, then shipping to all in orders. Most of customers will receive EarStudio by mid November or so. Thank you all for your patience!

    31. P.Frei on

      They will ship in October. Have a look at the update 9.
