Hi @FiiO
This page no longer shows the iphone/ipad message - https://www.aliexpress.com/store/pr...477.html?spm=2114.12010608.0.0.1e24e728MRtWc0

Are these the next edition ones mentioned earlier in this thread? Thanks.

@FiiO my rc-bt arrived yesterday. Sound quality is great for on the go IF it keeps a steady connection

Please give your advice before try to return them to aliexpress.
I use them plugged like your images (the cable goes on the back of my neck). My celphone is a Galaxy S8 with Oreo, i had no issues with bluetooth before.
my celphone is always on my left pocket or my left inner pocket of my jacket.

Now, my problems with this rc-bt.....
with my S8 in my pants pocket, the connection is complete unbeareble the music cuts every second.
with my s8 in my jacket pocket, i can have some cuts, its now listeneable (if this is a word) but if i the s8 is completely close to my body, the cutoff began to apear more often, like every 4-5 secs
all this can only be resolved by taking of my s8 of my pockets and be in the "sight" of the rc-bt

I have a sony sbh-56 with no problem at all in the same circunstances, this can pass at least a wall of my home (no more than 4mts)
pd: the sbh56 are clipped in my backpack at my shoulders

And since also my bluetooth speakers can work with my s8 in the same pockets and my walking around. i guess i have a defective unit (or this are no fiio quality)
had a lot of fiio products and this is the first with problems

Dear friend,

Yes, next batch is available now.

Best regards

@Fiio audio fan Thanks for the heads up! I've ordered my pair. I'm really looking forward to using them. I have some $8 BT mmcx cables that work OK, but their battery life isn't great.

Dear friend,

Here is some explanations about Bluetooth Connection — From James: http://fiio.me/forum.php?mod=viewthread&tid=43331&extra=page=1
Human body would absorb Bluetooth signal. Since the human body absorbs the2G-3G high frequency signal most strongly, it is necessary to prevent the body from blocking the Bluetooth signal during use. For example, putting your Bluetooth transmitter in your back pocket and put your Bluetooth receiver on your chest will seriously affect the Bluetooth transmission. Therefore, please try to putthe Bluetooth receiver and transmitter on the same side of your body to avoid signal blocked by your body.
We will also report to the engineers about the issue you met and try to improve it. Sorry for bringing inconvenience to you.

Best regards

@FiiO Three quick questions:

1. Is the BT antenna only on the control side? The non-control? Or both?
2. I assume that all orders after your comment earlier will be for the second batch. Is there an easy way to confirm that it is indeed from the second batch?
3. Will it automatically use AAC when connected to an iPhone? Or do I have to change settings?

Dear friend,

1. The Bluetooth antenna is only on the control side.
2. The volume control is non-synchronous when connecting to the iPhone, if the one you own is the second batch.
3. Automatically.

Best regards

Im not an expert but i had some experience with other bluetooth earphones, smartwatch and speakers and this are the first they gave this problems
I now there are a lot of stuff that affects the connection, even like passing in between of the device. but that only happens if some of the devices have a poor BT. sad to say but this rc-bt have poor connection
my iconx 2018 never had had a disconection and any glitch playing music. (but they sound mehh).
SInce returning this to china is a cost for me, i guess i will keep them just for the gym

Hi.
Just to be sure In understand: on the second batch of RC-BTs, the buttons on the earphones change the earphones' volume but do not affect the iPhone's output volume?
(I have just received mine and would like to be sure in which batch they were)

Thanks in advance

Hi.

I just received my RC-BT and here are my first impressions.

I use them with an iPhone 6s and Shure SE535 earphones with replacement shells (that's what happens when you walk upon your earphones).
I also use the SE535 :
- with a Dragonfly Black DAC,
- with Shure's BT1 bluetooth adapter.
I only tested them with Apple Music, which uses AAC.
As a reminder, iOS, and therefore iPhones, do support AAC over Bluetooth, but not AptX or AptX-HD

First, I miss the iPhone controls (which work on the BT1), namely previous/next track and Siri.

Regarding the quality of the Bluetooth connection:
- it is very good indoors (as expected),
- outdoors, with my iphone in the front-left pocket os my pants,
- it is very bad with the cable in the back of my neck,
- with the cable in the front of my neck, the connection is as good as other Bluetooth devices (and the Shure BT1), but not Airpod-good.

Audio quality is very good and infinitely better than Shure BT1.
I guess that's due to the RC-BT supporting AAC and the BT1 not supporting it.
(this is using Apple Music's AAC tracks)

I have yet to test call audio quality (that is a big problem on the BT1 where my correspondents regularly complained about how they heard me) but it looks OK using Voice memos.

The battery level can be seen on iOS in the battery widget (I edited the post because at first I did not see it).

The travel box is way smaller than the one provided with the Shure SE535, but does not offer the same level of protection.

The volume on the earphones is independent from the iPhone volume (that s the second batch of RC-BT if I understand well) and that is a good thing: the SE535 are very loud and the adjustment steps on the BT1 are too big (the BT1 adjusts the iPhon's volume). For info, I use an attenuator (Shure provides one with the SE535) when using them with a wired connection.

To finish, 1 small issue: the box of the RC-BT indicates a battery life of 8 hours, instead of the 10 hours advertised on Fiio's web site.


Overall, for now I am very satisfied, in particular because I do not loose too much audio quality compared to a wired connection, which is definitely not the case with the Sure BT1.

Yes, you could have a try.

Dear friend,

It would be appreciated if you could share your experience in the show case page as well : https://www.head-fi.org/showcase/fiio-rc-bt-bluetooth-cable-with-mmcx-connector.23169/

We have confirmed with the engineer that the 8hs shows in the packing box is a conservative value. The RC-BT could work 10hs or so after fully charged.

Best regards

 

[kaleci07]

left fit oky but right mmcx module dont turn as it should be . bluetooth connection cuts randomly all the time ,volume %30 percent lower than fiio's orginal cable. There is back noise all the time when listening something .by the way im using Fiio F9 with it. Worst product i bought from fiio.

 

[greenkiwi]

My connection cuts out if I wear them behind my neck and have my phone my left pocket. This is a bit disappointing. My $8 bt mmcx cables didn't have this problem.

That being said, I just wear them in front and it's fine and they sound much better.
