Wire Speakers To 3.5 Headphone Jack

Does anyone know what size the headphone jack on the back is? I’m trying to find a set of speakers for it and I can’t find the size anywhere.

I bought this subwoofer to extend the low frequency range of a table-top sound box used with my Sony TV KDL-46HX850. I used the TV audio output (headphone 3.5 mm jack) to get the audio signal to the subwoofer using a cable with 3.5 mm plug on one end and two RCA (M) on the other end; then a Y adapter cable 2 RCA (F) to a single RCA (M) to the subwoofer. The setup works fine. Just required some adjusting of the crossover and S/W volume settings. Using the audio out jack set to "headphone" in TV settings, I discovered that I can control the S/W volume with the TV remote for fine tuning. The capture of lower range sound is great, and I love the small size of this sub in the limited space I have in the bedroom.

I was looking to send audio from the 3.5mm headphone jack on my Mac to the 3.5mm mic jack on my cell phone, because I had a professionally recorded voicemail message I wanted to use but my service provider only allowed live recorded messages. (I wasnt just going to hold my phone up to the speaker on my Mac, because it would ruin the quality.) I had a male-to-male 3.5mm cable I tried to use, with no luck. I was confused as to why it didnt work. I couldnt figure out how to do it and went to a few nearby stores looking for advice, but every sales person just looked at me with a confused look and had no idea how to help. Luckily I noticed B&H was around the corner from a job interview I had. Ive always wanted to go there, just never got around to it until that day, and boy am I glad I did. I spoke to a gentleman in the Pro Audio Dept and after about 10-15 minutes of carefully listening to my needs, and taking the time to understand what I wanted/needed he informed me I needed an attenuating cable because the voltage coming out of the headphone jack would have destroyed the mic jack on my phone. I was finally on my way, but then just as I was about the thank him for his help he exclaimed WAIT!! and informed me that the two jacks were configured differently, (the headphone jack was TRS, and the mic was TRRS) and I would have no luck with just the attenuating cable so he pulled up this item on his screen explained it would convert the connector to what I needed and sent the whole order to pick up. I purchased and picked up the two cables and excitedly went home to test out the items. They worked!!! tl;dr This item was exactly what I needed, and it did its job perfectly.

The headphone out jack on my PC speakers finally wore out, so I needed a new way to select audio output to either speakers or headphones. This switcher seems well-built and makes it easy to quickly toggle between output sources. Being made in the USA is a nice bonus!

I like the warm sound this amp delivers through 1970s era stereo speakers via a headphone jack hook-up to a mac-mini. Also a subwoofer I can control with the bass knob. I got the usual top-grade professional advice in a question chain via email. I would shop here again and again.

My mom uses computer speakers connected to the headphone jack on her Mac Mini. The jack failed (evidently this isn't uncommon). As an inexpensive workaround, I picked up this USB audio adapter, and it worked like a charm. Even plugged into a USB hub, it stays recognized and selected in the Sound System Preferences pane even after rebooting and waking from sleep.

Before getting this unit, I ran my four amplified audio speakers from the headphone jack on my iMac. Using audio for editing in Final Cut Pro, but also watching movies at night, I had a nest of splitters separating the stereo lines to the various speakers and also to my headphones. A friend suggested the quality would be better with a digital audio converter, so I purchased this one. I am thrilled with it. I ran all the wires under my editing table and the master volume knob is right there at the front of my desk where I can adjust it when the volume gets too loud (Bruce Willis movies, etc.) And the headphone jack is right where I need it, cutting out the amplified speakers just by plugging it in. Its the most useful addition to my computer in a long time.

These speakers sound great. They don't contain a cable to plug into the headphone jack on the computer. I had to go into my sound settings to activate them, bt that is a lesser issue. It's a great product.

An alternative to using the headphone jack on your MacBook Pro.

needed it for an iphone w/o the headphone jack
