Bose Headphones digital piano usage? #2494258

I received Bose model 25 headphones for Christmas and I am trying to make it work with my Casio Celviano Grand Hybrid. When I use the headphones with my iPhone, the sound is excellent. However, with the Casio, the sound is muted even with my volume at 100%.

Is there anything I can do to make it sound better? What I've troubleshooted thus far:

The Bose headphones have a microphone so the jack is TRRS (3.5mm, 3 ring/4 pin).
I have to use an adapter to make it fit the 1/4" TRS jack in the Casio.
I thought since the adapter was TRS to TRS, that may have been the issue, but I just picked up a TRRS to TRS adapter which then had to run into a cable that adjusts for the 1/8" to 1/4" size difference.

After all this, the sound is still muted. In fact, the TRRS to TRS adapter doesn't even work. With that, there is no sound at all.

Any other suggestions? I'm not sure why Bose doesn't make a 25 model that has a standard TRS jack for use outside of iphones or gaming. If all else fails, I would return the Bose 25 but would appreciate any suggestions. Ideally, I'm looking for great sound but with good noise cancellation. Where I play has a lot of ambient noises, so headphones are not good without having the option to have the noise cancellation.

Thank you for all your help and/or suggestions!

Most headphones that are in this price range are going to do this now with the 1/8" plug. That's not the issue. Each model of headphones will have different aspects of a sound that it will accentuate and diminish, like speakers do.

From what I've seen on the Bose, they do need about 100 hours of "burn-in" for them to be at their peak sound. You can read the first review on amazon.com for more info on that.

I've never used them, so take that for what it's worth. smile

Despite the fact that the sound is muted, is it stereo, and otherwise good quality? I.e - is the only problem that the sound is quiet? If it's stereo, I think the connections are probably ok, and for some reason the Casio is having trouble driving those headphones loud enough, but that would be most unusual.

Just btw, I have a similar problem with my Akai AKG K391NC in-ear headphones - they also have a TRRS connector, and with some receptacles, I have to pull the connector out just slightly, so there's about 1mm of clearance. I haven't bothered trying to find a proper TRS to TRRS adaptor that solves this problem yet. Anyway, if you haven't already, you might like to try pulling the headphone plug out just slightly.

When I plug mine in all the way, the sound will be muted and also mono.

When you say "muted", do you mean it's too soft?

That may mean you need a headphone amplifier, though I can't see how your Casio can't produce an output at least as strong as that from your iPhone. If you mean that the sound itself sounds strange (like mono), your adaptor may be defective. I discovered that a cheap adaptor I once bought online didn't work properly.

I used a Bose QC2 when I was auditioning DPs five years ago. It came with a good 3.5mm to 6.35mm adaptor, and worked perfectly with DPs as well as portable devices.

Of course, there is always ... BOSE tech support.

i have a QC model 25 from Bose. if we are talking about the same headphone, the cord is modular. it should unplug and there is a hi/lo switch on the cord end. just flip it the other way. also you should have gotten two cords. one for a phone and one without. use the cord without the mic.

If the headphones have a microphone ... are you sure you want to use them with the piano?

That unit sounds more like a telephone headset, rather than a quality audio device.

Probably due to the TRS adapter touching the second Ring where it should be touching the Sleeve

You want:
T -> T
R -> R
R -> floating w/o connection
S -> S

but you are getting:
T -> T
R -> R
R -> S
S -> floating w/o connection

Ground reference is missing, so amplitude is messed up. Use a correct cord or use a correct adapter that's TRRS friendly.

+1 to WarrenY.

I don't know if the TRRS spec for an iPhone is the same as the TRRS spec for Android. There are two different models of Bose QuietComfort 25 phones -- one for Android, one for iPhone.

A call to Bose tech support would certainly be a good idea, unless you can find something on the Web. And this might be interesting:

I suspect the info Charles has linked to is probably on the money - some headphones I used a while back with my digital piano had a microphone in the cable, and just had a 3.5mm jack as standard, so needed a 3.5mm female to 6.33mm male adaptor - but even then the sound was, to use the term you used, muted.

I found that using a 3.5mm to 3.5mm adapter (made by Belkin, I think sold as an iPhone adapter) in line, before using the adapter to go to 6.3mm, made the sound correct again.

About TRRS, according to Wikipedia :

Two different forms are frequently found, both of which place left audio on the tip and right audio on the first ring (mirroring the configuration found on stereo connectors). Where they differ is in the placement of the microphone and return contacts. The first, which places the ground return on the second ring and the microphone on the sleeve, is used by Apple's iPhone line, HTC devices, latest Samsung, Nokia and Sony phones, among others. The second, which reverses these contacts, is used by older Nokia mobiles, older Samsung smartphones and some Sony Ericsson phones.

Just read this. And stuff that suggests you can get lo and hi impedence stuff. They dont tell ya what you get, usually, till youve bought the bloody things!

Shouldnt matter what you play through em, surely? And the headphone preamp?

Do me a favour, this is the 21st C. . . Just imagine sending a guy up to Saturn or somewhere "Are you receiving me, Bill??"

"Can ya speak up? Its muffled! Cant find The Bloody Gold Plated Adapter. . "

"Dammit, gave ya the wrong phones. . .those were for me laddos ipad. . . "

"Wassat ya say? Turn right at Mars? Thought it was left. . ". .CRASH!!!! . .tinkle tinkle . .expletives . .

"Ground Control speaking. . . Guess we better try again next time theres a hole in the clouds. . ."

Oh well. Might have a rethink on those new phones I was gonna get!

If you have headphones for iPhone, there are adapters that switch pin 3 and 4.
