Passive headphone amp?

[Hobobob]

Does anyone sell a passive headphone amp? Something with just a 1/4” plug, step-up transformer, and 1/8” output jack? Maybe passive volume and tone pots? If I had any aptitude whatsoever for electronics I’d build it myself but I wanted to see if anyone sold something like this.

Apologies if this is off thread but I rate this the single best gear purchase I’ve made. You can play bass only or blend your bass with audio off your phone (each adjustable separately) and all in super high fidelity… ie your bass actually sounds like your bass! It’s kind of a mobile studio which I take everywhere so I can work on ideas any time any place.

Not sure I am understanding this . You want a passive amplifier ? Like no electricity involved ? Or an amp for a passive bass ?

uhm, it doesn't work like this.

to convert an instrument level signal to a headphone level, you need to literally amplify it. no, you cannot do this with a passive 'step-up transformer'.

a common passive DI has an output in the -40dBu ballpark, a professional headphone amplifier is like +20dBu, that's a huge difference.

I use the Vox bass headphone amp. It goes for about $49.95. Works fine. I would suggest using rechargeable batteries. Good luck.

Passive headphones?

Maybe try a stethoscope?

Passive headphones?

Or cut out the middle man and just press your jaw against the bass, bone conduction!

Maybe try a stethoscope?

I'm pretty certain the back pages of Bass Player magazine used to have ads for exactly that:
a stethoscope rebranded as "bass headphones".

Only one I know of

Noggin Rockers stethoscope-style amp not sure it is still available?​

erm... I think you'll struggle to find a *passive* headphone amp. It'll need power from somewhere. Or magic.

I do seem to remember seeing that.

Why not right?

Works well for special ops headsets. Those use bone conduction phones and throat mics. Supposedly bone conduction was also what Beethoven used when his hearing really got bad. Pressed a rod against the piano case over the keys and pressed his chin against it.

I used a product like this when I was touring a lot. No EQ, of course, but I didn't have to worry about power and I could hear myself over the touring van background noise!

 

[CryingBass]

Yep. I use this. Your mileage will vary.

 

[Short4since64]

Would violate the laws of physics, over which mere humans have no influence. Such a device could conceivably be possible with noise-canceling phones which have internal amplifiers and batteries.

I've never heard any speaker that did not require some kind of power to produce sound, no matter how big or small. I think every guitar or bass amp, or earbud is always active, because it requires some kind of power to produce sound. It is possible I misunderstand your question or definitions.

 

[Killing Floor]

"Amp" is an abbreviation for Amplifier. Amplifiers are active when they are operating.

You might barely hear a high output active bass with its tone controls at max through headphones plugged directly into the bass output jack. Unless you have adaptors or a stereo jack in the bass, you will only hear it in one side.

Here’s a fairly cheap way to have a headphone amp with effects that is rechargeable and portable. The quality of the effects & the noise level of the amp might not be fantastic…—->.
