Have a question?
@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.
@Radstone, thanks for the reply. By the way, what bluetooth version is being used?
@Raymond Liew - we do not send confirmation email for address submission. You've answered your survey, and I messaged your submitted address for your reference. Thank you.
I didnt receive any confirmation email for address submission. how can i get it sorted?
@Kai Wang - It is probably the best if you provide us your new address. please message us. Thanks!
@heejeong - 안녕하세요, survey 답변하셨습니다. 기재하신 주소 메세지로 보내드릴테니 확인 부탁 드립니다. 감사합니다.
@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?
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?
when you will ship out batch for north america? i need to move first week of November, not sure which address i should provide you.
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
@wanderer.gd - 안녕하세요, 발주가 완료되어 색상 변경은 더이상 불가능 합니다. 감사합니다.
혹시 주문색상 변경이 가능한지 궁금합니다.
@Ang Chun Yong - thank you for supporting us. As mentioned in our latest update, we will begin shipping from late October to November. Thank you for your patience!
Hi would like to check is the product ready for shipping? Can't wait to try it.
@yuro mizusaki - please message us your updated address. Thank you.
@Hyunwook Jang - 주소 변경 해드렸어요. 감사합니다.
@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
Due to my sudden movement, I'd like to change the shipping address. Could you advise me how to update it?
주소변경 다이렉트 메일을 보냈습니다. 그런데, 처리 답변이 없으셔서요. 처리 결과 알고 싶습니다.
I Have ordered White but the black looks pretty, Is it possible to change my color preference now
Any chance of more 2.5mm cables being made available?
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!
Is there any noise cancellation with this device?
@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!
They will ship in October. Have a look at the update 9.
Hi, is the delivery on September? May I know the shipping details
Does the EarStudio incorporate Qualcomm cVc noise cancellation technology to improve voice quality?
Sept 20 shipping date ???
Any update on a actual shipping date?
Looking forward to month end or next update on shipping! Cheers!
@Ang Chun Yong Thank you for your suggestion and we will definitely take that into consideration.
Hi. Like able to change to a dark background
@Vincent Zuo Give us a direct message and we will give you a URL where you can add the 2.5mm MMCX cable to your pledge!
@Ang Chun Yong Could you give us the reasons and suggestions? We are always open to change.
Is it too late to add a 2.5mm MMCX cable to my pledge? When I first responded, I forgot to add it
hi would like to check on the mobile app for the dac. Is there any option to change the theme or color?
@Hyoeun Kang 안녕하세요, 저희에게 direct message 부탁드립니다 :) 감사합니다.
@firstname.lastname@example.org 안녕하세요, 배송은 10월말에 시작될 예정입니다. 직접 수령은 불가능합니다ㅠ 자택으로 주소 지정하셔서 받으시길 바랍니다. 감사합니다!
주소가 길어서 입력이 제대로 된 것 같지 않아 문의드립니다.
한국어로 주소를 입력해서 알려드려도 될까요?
언제쯤 배송 가능한가요?
필요하다면 판교가서 수령도 가능합니다
