I've been using my running headphones with my newest phone for a while now. They are okay, but hurt my ears after a few hours. The most comfortable headphones I have are old Shure SRH440... which only have a wired connection.

I found a USB to 3.5mm audio adapter on AliExpress (apparently from BLUEKAKA):

I also needed a 3.5mm to 2.5mm audio cable, since the one from the headphones are a huge coiled affair designed to prevent kinks in the cable... great for recording in a studio but not very handy when walking the dog.

After hooking everything up it seems to work well. Yay!

Anyway, I was just carrying everything around loose until I realized that it was small enough to just strap onto the headphones. I used a hairband that my wife left lying around to attach the adapter.

It looks really janky, so I'll probably 3D print a nicer looking setup eventually.

That looks Macgyvered as fuck, and i love it. I've done something similar before, but just temporarily and not attached to the headphones. I plugged my AKG K712 cans into my portable headphone amp, and that to a Bluetooth audio receiver. Then, had to have a power bank to run it all. It all fit into a Nintendo DS carrying case, but definitely not as convenient as having it attached to the cans.

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of “discuss” rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This isn't an advice forum

Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with “So” - starting a post with pointless phrases, like “I hope this is allowed” or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.
