Only open to test with my own tips. Comes with original box and tips. It barely has 2 hr listening time on it. I do see some scratch mark on casing. Mainly selling because I have moved to wireless earbud and I have no use of wire one.

Brand new sealed. Accept PayPal gift or add 3% for the fee. Price include USPS first class package with tracking.

Thanks for the update. Regarding, 7.2, do you think there will be a way for the device to remember this setting? It really defeat the purpose of the setting if I have to manually turn it off every time device is reboot.

Have you heard of the Xiaomi bluetooth receiver? Though it is not as good as BTR1 in term of sound qualify and battery life (~4-5 hours), it does exactly what you wanted. The in-line remote on the headset works perfectly. It is also much cheaper than BTR1.

I meant updating Spotify app. I don't think you can update the BTR1.

I would recommend that you try it with other apps, such as YouTube, Pandora, etc. The button did not work with Spotify before the most recent update. Now it does. I think it is something to do with Spotify.

Does the volume button work on the BTR1?

The middle button can be used to play/pause on my pixel 2. What phone are you using?

I do not have the fiio f9 but I do have the Xiaomi piston 3 and the stock Samsung android headset. the in-line remote (volume and play/pause) did not work on both. You will have to use the BTR1 remote.

Does anyone know where in the US will I be able to buy the short MMCX fiio cable? I couldn't find it online except in aliexpress.

Is there a way to sign up for promotional email to keep update on the next deals? I am waiting to get the f5 at this price.

Thank you Gilly87 for the recommendation.  I went and purchased a used nexus 4.  However, I noticed there is some problem with the phone's mic when I am using a headphone(no mic).  During a call, I would hear myself as though as I am listening through the phone's mic.  I tried to on different...

Thank you for the suggestion but it is little bit to expensive for me as I am trying to get something less than 100.

Thank you all for the advice! However, I am not sure if I will buy these at the price of 79 when the new re400 is just 99.  My budget is 100.   Do you guys have other suggestion beside the re0? Thanks!

I am interest let me know.
