My daughter runs a Pre-school and uses a small cd stereo setup. The output is a pair of mono jacks (R/L) for speakers. I am looking to build a distribution box for up to 6 headphones. Thinking of one input (from the speaker jacks using a 2 to 1 plug) The headphones are mono 1/4 so those jacks are readily available. I do not know what the output is of the stereo system is but I doubt it is much over 5 watts (if that). Will I need some sort of amplifier? any thoughts on switches/switching jacks if not all are being used. Thanks for listening. guitar 52

I'm currently in a dilemma over the next pair of headphones I'm buying. Does anyone have anything bad to say about certain ones? (Or better yet good things). The three I've narrowed down to are: - Solo HD's from beats - These are a tad more expensive, but I personally like them and have heard great things. - Detachable cord - Great sound - Most expensive (119USD) - Skullcandy Lowriders - I've gotten mixed reviews here, some say that they are crap yet I personally know someone who had a pair of these for 3 years and they were still in one piece. - A little uncomfortable, but durable. - Decent sound - Also the cheapest (40USD) - Ifrogz Vertex - I have a pair of these which are broken, the cord is a tad cheap but the quality is fairly good otherwise. - Decent sound - Mid priced (50USD) Thank You - Nerdman

I have been wanting a good pair of headphones for a long time now and I have looked at many things but have not yet found quite what I'm looking for. I want something affordable ($150 max) but good. I would prefer headphones but if you know of a good pair of earbuds feel free to tell me.

Hi, I am working with a Flyron FN-M16 MP3 player module which has both output for headphones (pins 4,5, and GND = 7), and a 3-watt amplifier for speakers (pins 6 & 8). The problem I am having is that I am unsure of how to disconnect power to the speakers when headphones are plugged into the jack. This is easy when you have a separate amplifier circuit, but here the amplifier is built in. The easiest solution would be to find an audio jack with an isolated NC (normally closed switch) to disconnect the speakers. They do not seem to make them in SMD packages. I have found a 3.5mm stereo audio jack with an isolated NO (normally open) switch from Technik.HK. Is there a mosfet type circuit that I can use to disconnect the speakers when the NO switch is closed without introducing any distortion to the speaker sound? Any advice for an electronic disconnect? P.S: The manufacturer has stated that if I ground the speaker outputs for the 3-watt speakers I will blow out the internal amplifier on the flyron Mp3 player board.

We have 2 pair of the wireless Sony headphones for TV watching and one pair has snapped right above the earpiece on the 'plastic' framework. What is this stuff made of and what works as an adhesive? Neither superglue or JB weld seems to work.

I have a pair of airline headphones that have a standard 3.5mm jack for the audio but require power to an additional 2.5mm jack in order to work. I'm looking to use them with a desktop PC so thought about getting the power supply from the USB but am a little confused about how I can get it there, I've had a look around on ebay to see if there was someone that was selling a 2.5mm female to USB jack but havent managed to find what I need. Do these things even exist? Or would I need to get myself a 2.5mm female connection and wire it up to a USB lead myself?

I have a few military headsets (MSA Sordin type 75311). These headsets come with a TP 120 plug that goes into various vehicle systems. Ideally what I'm looking for is how to make a converter to convert these TP plugs to a mini 3.5 mm jack. I've seen such a converter on Ebay so I know its possible.

So I'm trying to convert a vintage pair of over-the-ear headphones into a microphone (using only one of the earpieces obviously) and I'm not sure how to re-wire it after I went and disconnected the 2nd earpiece. Basic info: The remaining earpiece has a tone knob, volume knob, and a mono/stereo toggle switch. It has a 1/4" cord compromised of positive, negative, and a ground. It's a 0.3W 8ohm speaker. I got the idea for this after seeing an old telephone converted into a microphone and I've been wanting to get a lo-fi sounding mic for a while now and figured I'd save some cash by recycling these old things.

Question by JoshuaI6 | last reply
I bought this amplifier kit and I'd like to know what its capabilities are. I was going to make a Chu Moy headphone amp but remember that I bought this a while ago and never did anything with it. I'm going to guess that this isn't a top-notch amp, but I was wondering what I could get away with by using this. Specs: music power output: 7W / 4ohm RMS output: 3.5W / 4ohm or 2W / 8ohm total harmonic distortion: 0.05% (1W / 1kHz) frequency response: 20Hz to 20kHz (-3dB) signal/noise ratio: 86dB (A weighted) input sensitivity: 40mV / 150Kohm overload and short-circuit protected supply voltage: 15V DC (8 to 18V DC possible) / 0.5A dimensions: 2.2 x 1.4" I'm assuming that this would be good enough for use as a headphone amp? Would I be able to run this off a 9V battery?

First things first, they look like Beats, but I’m pretty sure these are knockoffs. Nonetheless, they sound pretty good, and I picked them up at Goodwill for a steal and love a challenge, so if someone is interested on taking on this electronics mystery with me I’d be incredibly grateful.Context: I’ve tinkered on and off with consumer electronics for a while now, am okay at soldering and have an okay knowledge of how more basic circuits work. Otherwise, I'm pretty beginner but generally a quick learner and would be happy to try any of your suggestions. The previous owner attempted to replace the AAA battery holding component with a rechargeable lithium ion battery - only problem was there was no way to charge the battery. Not a huge deal, fixed the headphones to run on AAAs again as they were originally intended. That said, pressing and holding the power button powers the headphones on, but also is the Bluetooth connection button on the board (image at the imgur link below) there is an icon for both the connection functionality and the power around the same button. The headphones power on, work, and sound great when you're holding the button down, but once you let go they turn off. So, it’s a momentary switch with no latch to keep it held down - not ideal. That said, I’ve tested jumping the switch so it gets constant power without holding the button down, and while the headphones power on, connect to my phone, and work, because it seems the power button and bluetooth button are one in the same, the headphones continue to look for Bluetooth devices and makes a periodic and infuriating beeping sound about every fifteen seconds. Based on the pictures of the board below (pictured with, and without button attached) can anyone figure out what the problem might be? Or point me in the right direction for further tests to run?Front of the board, with buttons.Front of the board, with power/bluetooth button removedBack of the board, held upright with power/bluetooth button side up

Hello, I am trying to create a universal remote with my android. I have been trying to light a remote led using my android headphone jack, but I have had no success. I am running ARA Smart Rem on my android to produce the signal. I pressed the button on the remote and I can see the light on my webcam, but I can not see the light when I power it with the headphone jack. I connect a stripped headphone plug with a pair of with alligator clips to the led. The media volume is all the way up. How do I get the light to light up?

The headphone amp I built awhile back is working pretty good, but recently I saw something about matching speakers impedance to the circuits impedance or something like that. IDK. Is there something you have to do to regulate the output to "match" your speakers. A google search brought up something about a peak resonance....

My panasonic tv does not have bluetooth. I have new Marley headphones. Theywork well but not when the channel says Dolby or no good with Netflix as they appear to all transmit in Dolby. I purchased both a digital to analogue converter and bluetooth transmitter as advised but still cannot get Netflix audio or those channels using Dolby. Is it because bluetooth will not transmit analogue??

I've got a cheap voice changer that is hard-wired to a computer-style microphone. I cut off the mic and added a 1/8" miniplug adapter, so as to increase flexibility. I need to connect the powered headphone output of an mp3 player to this voice-changer, what is the easiest way to do so? I tried an attenuator I had lying around, but got no results (are attenuators one way?) is there a good (cheap) solution to this problem?

Question by plasticpopcorn4 | last reply
Hi guys, I'd like to take an existing pair of headphones (not a specific pair, I can buy a suitable pair if this will make things easier) and implement a switch that will automatically pause my android music when a switch is pressed. Specifically, I'd like the music to pause when a circuit is broken. Since Android will automatically pause music when the headphone jack is removed I can't imagine this would be too difficult to build. However I would also like the music to automatically start again when the circuit is closed again. I'm not overly tech savvy but I think this project is within the realm of my capabilities! Any thoughts or help would be much appreciated! Regards, Tig

I purchased a set of crystal radio headphones on ebay which I wish to remod into working headphones. Instead of using the same cableing that is already on a set of regular headphones I wish to install in the old ones, I wish to solder new, thicker wireing onto the crystal radio cups and solder a new 3.55 mm gold jack onto the ends. To help you understand there are 2 good tutorials online , but they dont explain what type of new wire to get or how to solder a new jack on. I am not 100% sure what type of audio wire to purchase. All the wire I see at the electronics store is the red or black kind, with the one solid copper wire or the regular gold speaker wire.. but headphone wire is different because it has multiple colored strands that I need to twist into 3 for Left/Right/Ground https://www.instructables.com/id/vintage-wartime-radio-headphones/ and http://steampunkworkshop.com/g-headphones.shtml I like the look of re-wireing new cable to the outside of the cups, instead of just running the same cable straight through the cups. New, thicker wire will stand up better and the new jack would last longer as well. I was thinking wire between size 18-22 maybe?

My friend, asked me to fix his headphones for him. The jack has broken from excessive stress. They are the metal skullkandy, with a built in microphone. I opened up the jack and, am really confused by what I see. There are four contact points on the jack but 5 wires. one ground, one green one blue one striped red and one striped blue. I have no idea what to do. There is a button on the microphone module but I don't see how that would wire up to the jack. Any ideas?

I'm trying to adapt a pair of headphones to a bluetooth module for a wireless headset. I'm using a common module found here. http://www.ebay.com/itm/311523753533?_trksid=p2057872.m2749.l2649&ssPageName;=STRK%3AMEBIDX%3AIT Spec sheet says "Stereo audio output can directly drive 40mW @ 32Ωspeeker without the need for DC-blocking capacitor" I have some old sony headphones with a microphone i would love to use but i cant identify how many watts and or ohms the speakers will need. I wont need the microphone, but if i can get it working it would be cool too. I've identified the headphones model as PSP-270X but i cant find a spec sheet that includes the type of speakers included. So i took apart the headphones but the only markings they have on the speakers are ATZ2261, And a couple google searches came up empty. Is there a way i could test these headphones?
