Hi there

How many Custom PEQ can be saved in the application? I`d need a couple for different cans. Thank you!
Dear friend,

Only one currently. How many PEQ would you need? We will report to the engineer for assessing about that first.

Best regards

Hi @FiiO: At least 5 custom banks, the more the better. Actually your competitor Qudelix has plenty of them and I reserved one for each of my IEMs / "portable" headphones + it is usefull to have a few extra slots in order to quickly A/B test different settings.

It would be also fine, if the user could overwrite the presets, if internal storage capacity would be a limiter.

Thank you.

@FiiO

Is it possible to make a battery percentage indicator in the new firmware for the device?
Dear friend,

Thanks for the kind feedback. This may not be added in the new firmware, sorry. But we will still record and report to the engineer.

Best regards

Very good synergy with Campfire Andromeda (3.5mm out as I don't have a balanced cable). It sounds like the output impedance is around 1.. it makes them dynamic and large sounding. Cayin RU6 makes them bit closed in/too warm. With the BTR7 they get a wonderful sparkle coupled with nice smoothness, warmth and precision.

Yes 5 would be great, 10 would be even better.. but I realise that the EQ preset can be changed from the BTR7 LCD, so too many to scroll through might not be best. I think the Jazz/Classical presets can be permanently removed - i will bet no many people if any use those who would get a BTR7

@FiiO I think i found another bug:

When I enable the PEQ via the app button (top right), the volume drops quite a bit. if I move the volume adjustment on the eq by a tiny amount (and back again to what it was), the volume jumps up a fair bit to how it was before I enabled the eq. There's something going on which is not right.
The correct way is to NOT change the volume automatically at all when eq is enabled, allowing the user to adjust it themselves on the eq volume slider is enough (same behaviour as Qudelix)

Update: it might also be related to this issue I noticed: Sometimes when I connect it to USB on my computer, the volume is less than it should be (as per the BTR volume settings, and maximum digital volume on computer)- when I go then and change the sample rate on the BTR from 44khz to something else/or back (I dont think it matters to which other sample rate) the volume jumps back up to it's correct baseline; as if something inside the BTR7 resets and the internal volume gets it's proper target.. which means I can never totally trust if the BTR actually gets the correct max volume for it's setting inside.

This might be related when going Bluetooth > USB perhaps, not sure, but something is going on which don't seem right (and unrelated to external factors like PC/Mobile device settings as I ensure their volumes are always maxxed out)

Mojo pushes the mids forward a little and with more details (a little overcompensating at times), it's more vivid in general. The BTR7 mids are a little smoother/etheral, but less detailed and less focused/defined - but still quite nice in their own way. The BTR7 seems to have a better controlled/faster bass - a thx trait.

If I'm honest I don't think the Mojo (2) is the killer DAC everyone makes it out to be - Softears RSV sound better and more delicate out of the BTR7, also quite wide. Out of the Mojo 2 they become a bit too hard hitting losing some of their subtlety and becoming aggressive. So with some IEMs the BTR7 can sound more impressive! I find sensitive IEMs that require a delicate touch the BTR might fare better. I haven't tested my big headphones yet.

I don't think there is a massive difference between the two - the obvious change in sound is with R2R dacs for me: the RU6 sounds distinctly different than the Qudelix/BTR/Mojo 2 - where i find the BTR7 and Mojo overlapping too much with SQ
Yeah, I also have the RSV + BTR7,
Amazing for metal music, 🤪
BLAST OFF !!!

I see you also have the Mest MK2 - how does it compare to the RSV via the BTR7? I was tempted by the Mest 2 but I read mixed reviews, some saying that it lacks coherency and some issues with imaging - weird placement of instruments + treble harshness... others said it's the next best thing since sliced bread.

I have been testing out the BTR7. Very impressed with it thus far but I am wondering if anyone has tried the small Fiio M5 to use as a streaming source to the BTR7. I am thinking this combo will make for a killer small form portable music on the go. If not I might have to try it out.

Can we connect the btr7 to an iPhone and then connect the utws5 to the btr7 in order to bypass AAC limitation?
This has been answered a few times in this thread already - No, BTR7 CAN NOT be used as a BT transmitter.

I've been doing some comparisons BTR7 vs Earmen Sparrow side by side via USB. Have to hand it to the Sparrow, it's worth it's weight in gold - with IEM specifically it has a more organic midrange, the highs are more refined, the bass is more bloomy and bouncy, and the soundstage is larger but also better defined by a good amount - there's clear space between the instruments and accurate localisation, to an extent one can almost hear the room they're in. The BTR7 ofcourse has more power (and lot more features), and can drive bigger cans - but I would say it's sound is about 70-80% of the Sparrow's with IEMs; there's some blurring in the high registers, a little less definition and soundstage, some slight feel of grayness in the background, and it just doesn't quite reach that wow factor and ease of the Sparrow, which is probably subconsciously compounded by how tiny the Sparrow is!

Anyway this is purely sound quality comparison - the BTR7 is indeed very good, but it's not quite a giant killer where the Sparrow kind of is when it comes purely on sound IMO (with all it's quirks).
