Going fully Wireless IEMs. Too soon? Or are we there yet?

WOW, just WOW!!! The tone generator really concludes my findings.
That was amazing! I can already say that I never will buy a BT headset with only SBC again

Source: Macbook Pro with AAC/AptX/SBC, using Bluetooth Explorer
(did some testing with iPhone X and a CSR 4.0 usb dongle too, with similar findings, but did it more thorough with the Macbook)

Headsets:
Sony WH-1000MX3 (tested SBC, AAC, AptX)
Sennheiser MTW (SBC, AAC, AptX)
Avantree Clipper Pro w/Soundmagic E11C (SBC, AAC (ref specs, it doesn't support AAC, but my Mac recognized it with AAC, AptX)
Jaybird X3 (SBC, AAC - no AptX support)
BeatsX (SBC, AAC - no AptX support)
RBH Prostereo H2 (SBC, AptX - no AAC support)

ALL headsets gives a really annoying high pitch/frequency noise with bass from 20-150hz with SBC! Quite simiilar to what I hear with the tracks I posted before.

All headsets (except the MTWs) do NOT present the high pitch noise from 20-150hz with AAC and/or AptX

The MTWs have the same annoying high pitch noise ON THE LEFT with 20-150hz with AAC and/or AptX

(Sidenote, all but the BeatsX was free of other noise, but the BeatsX had continously some "scratching/crackle" noise on low frequencies)

Not only the MTW, but possibly all current TWs that use NFMI. Unless there's some new NFMI chip that supports other codecs in addition to SBC.

Here's a reddit post on the Bragi Dash, same story...

But again, SBC doesn't necessarily sound worse than AAC or aptX, provided the bitrate is high enough.

There is a zero percent chance all of these companies have been making TWEs and having the one earbud only going in SBC LMAO are you guys for real.

I have to mention that I'm on my second set of MTWs, and got exactly the same "flaw" on both of them.

Just performed the tone generator test with my TRN BT20 earhooks + JVC IEMs.

• I can hear the high pitch noise clearly in both earpieces with SBC
• I cannot hear the high pitch noise in any earpiece with AAC

Thank you!

Thank you!

Well, but that means that either the TRN BT20 doesn't use NFMI between the earpieces at all, or that SBC via NFMI is not the culprit.

Sooo... why have both the MTWs I've got the same high pitch noise on the left with AAC?!?! NFMI - SBC?
Edit I wrote that just after you posted your last post.

I think we'll need more test results from different TWs that support AAC or aptX to come to a reliable conclusion.

I thanked mostly because you heared the high pitch noise with SBC... And of course that it was clean with AAC.
I thought I was going crazy when no one in here could tell me they heared the similar noise on the 3-4 tracks I've posted earlier.

 

[SomeGuyDude]

A lot of this is ridiculously anecdotal dudes. Unless you've got straight-up electronic information or schematics, just going "well I hear a noise so it must be in SBC" is ridiculous.

Come on, do any of you seriously think Bose, Sony, Sennheiser, AKG, Audio-Technica, Master & Dynamic, and Bang & Olufsen would all be making true wireless with HQ codecs that only goes to one ear??

Yes, but according to your theory, my TRN BT20 should exhibit the high pitch noise at the left side with AAC. Which it just doesn't, I'm afraid. It sounds clean at both sides.

And to make things worse... I just tried the Havit G1, which is SBC only. And that one is noisy at the right side, but not on the left. Go figure!

I don't say it's SBC on one earpiece on TWs.
I only say that SBC introduce this high pitch noise on these bass frequencies, while with AAC/AptX it's clean.
So don't you think it's interesting to discuss why the two MTWs I've got have this "SBC sounding" noise in the left channel with AAC/AptX?
No one has concluded that it's SBC per se, but if NFMI uses SBC... don't you think it's a possibility?

 

[clerkpalmer]

We have established that nfmi is sbc only. That’s a face based on what I’ve seen so far today. We also know that MTW uses nfmi. So I’m starting to be convinced. We need you guys to test anothe nfmi tw headset to confirm and compare to something like the Sony sp700n.

Also does bt20 support aac? I thought it was sbc only. Mine sounds like crap regardless.

I guess the TRN BT20 has got a different transfer codec/protocol between R to L /L to R than my MTWs then? (I'm Norwegian, not a very skilled tech guy so it's sometimes difficult to explain in english But you get what I mean, I hope )
Very strange with the Havit G1... None of my headset got the noise in just one earpiece with SBC

I don’t think trn bt20 uses nfmi. I say this because both headsets show up in my bt list independently.
