Audio Streaming / Bluetooth Equalization

I have recently switched from vented sleeves on my KS8 ’s to closed sleeves. One of the big differences I have noticed is that when I stream iTunes music from my iPhone the sound is terrible. It has no bass and the mid to highs are shrill. With the vented sleeves the sound was good, not excellent, but for sure way way better than what I am now getting.

Does anyone have any experience with this and what adjustments may be necessary? One of the things I noticed is that when you go into the Fine Tuning and Audio Streaming / Bluetooth tab in Connexx 8 there is totally different equalization applied by default for closed vs open fittings. I presume that is because the closed should be trapping the bass and less bass equalization is needed. But what I am hearing is not enough. I was thinking about asking to go midway between the two equalizations to see how that sounds. Thoughts on this?

Here is what the equalization looks like for the open sleeves. Each bar is one .

And here is what the closed sleeve equalization looks like:

I’m not sure I follow. What I showed above is the default when you select the two different sleeve types. The problem is that the default setting on the open sleeves was not too bad. But on the closed sleeves
the default is bad.

Trying to listen to any music through any hearing aid (only) is a drill in futility and silliness. Fidelity in hearing aids is totally nonexistent aside from high upper frequencies. Bluetooth or wired headphones are the ONLY option, with or without the hearing aids.

I’m a new user and I’ve had Marvel M90-R’s since Dec 26th. I’m going to differ with you. I stream my music from my Google Play Music subscription. For Christmas I received a Sony WH-1000XM3 headphone. I returned it to Best Buy and got my $350 back because my Marvels were better than the headphone.

Everyone’s experience is hugely subjective and based on their loss, the output on their aid, venting and the impedance of their canal.

Saying that brand X is better than brand Y is pretty meaningless too as differences in programming will hugely influence the perceived sound quality.

In addition, most aids actively mix the input from the ambient via mics with the streamed content too, for safety purposes. That’s three sound sources: Ambient via venting, Ambient via Mics and the Streamed content.

If you think about it, it’s not entirely surprising that under different conditions the pre-determined mix is going to sound rubbish. Unless you have a combination of decent initial settings, sufficient isolation, good dynamic controls and preferably some form of user input - you’re going to run into less than ideal listening situations more commonly that you’d like.

Based on the very significant default equalizations that Connexx puts on the ’s for streaming, it is obvious that streaming with all the sound coming from the HA’s is very different than signals coming from the microphones and vents. And on top of that, their default equalization for the closed vents just seems off.

What is the actual issue your having? one thing is you can’t hear the changes made on the fly, you have to disconnect your each time you make adjustments in Connexx, another thing is microphone attenuation, I think the default is 70% drop it down to say 30%.
I’ve forgotten, are you using domes or molds?

hi bro.
using molds.
my issue is that I am not an audio engineer so I have no damn clue about how the equaliser must be set in order to get good streaming sound :smiley:

I checked Phonak and oticon’s software, both dont have this option like Signia has :muscle:
can’t wait to get my molds from Signia in order to restart my trial

Yeah it’s usually a problem with “Bass” you won’t have to much problem here if the vents are small, but I found I did a bit of adjustments with the higher frequencies as well, I just played a couple of songs from my playlist on my phone, once I got these sounding how I like, everything else was pretty good, I’ve used this as well, a tone generator can be helpful.

Warning, may be off-topic: very interesting to see what the equalisation adjustment looks like inside adjustment software (Connexx8), and that it stops at 8KHz and doesn’t go up into the range of 10 to 16 KHz.
Is this true for most HA adjustment software?

Yes, there’s no point as the receiver bandwidth tops out at around 10KHz (though in reality nearer 8KHz for usable amounts of gain).

So the output/gain profiles are modelled to reflect this.
