Glass recently released headphones and a mono ear bud. This implies that it is capable of producing an audio signal from the Micro USB port.

Is it possible to create an adapter for Glass to connect to a standard audio connector, such as a 3.5mm headphone cable?

  • I typed `micro usb to 3.5mm` into Google and found this: http://www.ebay.com.au/itm/Micro-USB-Jack-to-3-5mm-Headphone-Earphone-Adapter-Socket-Audio-Cable-Black-/160818117801 – ta.speot.is Nov 02 '13 at 02:02
  • It needs to be supported by Glass, it's not clear if this would work since it needs some level of driver support. Thanks though I'll look into it. – Brandyn White Nov 02 '13 at 02:08
  • this seems like a neat hack (also on XDA), but it also seems like a cable you'll receive in the upcoming consumer Glass replacement - https://lh4.googleusercontent.com/-bkYDAu3OM5I/UnAxaJ_3NEI/AAAAAAAAPGU/vFY8ginsvx4/w1068-h712-no/earbud1.jpg – ina Nov 02 '13 at 03:11
  • The _explorer_ Glass replacement only comes with a mono earbud and a fixed cable. The cable is very short and thin. – lilbyrdie Nov 20 '13 at 19:26

    @Andrew Barber Why was this question closed? This was very helpful. – Jared Burrows Nov 26 '13 at 16:08
  • This question appears to be off-topic because it is about hardware. – Andrew Barber Nov 26 '13 at 16:11
  • lilbyrdie: That's not the consumer replacement but V2. It's also not a cable but a mono-earbud. The answer below is from one of the actual Glass Engineers (Jenny Murphy) and provides the details needed to develop your own true, 3.5mm adapter cable. I've already seen one built and tested successfully. I'm going to build one as soon as Amazon gets me the parts and I'll provide a video walk-through of the build and test. Follow "Michael-Rainabba Richardson" on G+ if you're interested in that or other Glass info (I'm a Glass Explorer and developer). – rainabba Nov 30 '13 at 19:27

If you're handy with a soldering iron, it's pretty easy to make an adapter. Solder a 500k ohm resistor between pins 4 and 5 (ID and GND).

You'll need the following parts:

Once you have them, follow these instructions:

  1. Open up the headset adapter and take a look around. If you ordered the one linked above, you'll find pins 4 and 5 connected by a solder bridge, but if you have a different one you may find a something else, like a resistor.
  2. Desolder pin 4 if you need to.
  3. Solder the 500k ohm resistor between pins 5 (GND) and 4 (ID).

  • Awesome! Having said so, the microUSB adapter you mention has the 'L' usb pointing front. Would the same work with this one? http://www.amazon.com/Headphones-Earphones-Earpieces-Converter-Micro-USB/dp/B006G1FX9U/ref=pd_sim_sbs_cps_5 – tdevaux Nov 12 '13 at 22:37
  • Maybe? As long as it has all 5 conductors, you should be fine :) If it works, please report back. – mimming Nov 12 '13 at 22:43

    Bought the one @JennyMurphy linked to, works great. Shell pops off clean for easy access. I had to cut an alternate exit hole straight out the bottom to fit a coaxial 470k resistor, so the fact that the original cable points "forward" isn't an issue. – rymo Nov 20 '13 at 06:24
  • @tdevaux Have you tried this adapter? – Jared Burrows Mar 13 '14 at 22:34
