    I really like my Q2, but the Bluetooth volume is low like all BT devices and the speakers are typical helmet speakers. No wind noise isolation and without a way to move them closer to my ears or somehow create a "tube" between them and my ear I had difficulty hearing anything coming over the BT. I also didn't like the fact I was subjecting my ears to so much wind noise so I decided to come up with a better way. All I did was cut the speakers off a spare Cardo dock ($30 I think) and solder on a 3.5 mm female stereo audio socket. Now I can plug my Shure E530s in and have great isolation, much better audio from the MP3 player and be able to hear phone calls and GPS prompts. Pretty simple other than soldering these eeensy weeeensy teeeeny weeeeny baby hair wires onto the jack...ugh...

    Works like a dream...exactly what i wanted. Cost me the dock and $3 for two jacks from Radio-Hack.

    Sent you a PM with a dumb-ass question.

    Good looking modification!

    Great idea. A have a pair of Q2's on the way. I think that I'll be doing this mod ASAP. I'm going to cheap out a little bit and use some generic noise oclusive in ear units. This kills two stones with one bird!

    P.S. What was the wire color code?

    I used the Shures because it's what I had on hand. Make sure whatever you get fits fully inside your outside ear otherwise you'll have a PITA getting your helmet on without ripping the phones out of your ear.

    Wires are red and black and as it's mono it doesn't make any diff how you hook them up. I used a stereo jack, but tied the reds together and the blacks together to make it easier for me to solder. The wires are really fine and hard to work with. Tin them out to about 1/2" long to make it easier to work with them. I used a piece of heat shrink on the last 2" of wire and shrunk it right onto the stress relief on the jack to clean it up and try to weatherproof it a bit. If I do it again, I'll fill the back part of the jack with epoxy to weatherproof it for sure.

    Good stuff. I'm familure with the hair thin wires because I have to repair DJ's headphones all the time at work. Total PITA working with them and it can be difficult to get them to take solder because they are usually varnish coated.

    I have had this same discussion with others on the Q2 but have yet to do it. Nice to see it is working for someone.

    I actually have no issue with the volume of mine but I did space out the speakers with additional velcro so that the speakers where closer to my ears. I also wear earplugs and find that i can actually hear better with them then without at highway speed.

    How do the earbuds compair to earplug quietness?

    I was going to use some 1/4" foam to get the speakers closer to my ears, but I wanted to kill two birds with one stone so I went with the canal phones to get the noise isolation and better sound quality with lower volume.

    The Shures are well known for high isolation of ambient sound. It's really wonderful to ride and have all that noise blocked out

    I did the mod to both of my Q2's today. I didn't have any problems at all but there is a third wire in that is not connected to anything once you cut and strip the right ear wire back. Don't let it throw you for a loop, it's not connected to anything.

    I connected the wires like this, The Blue and Green solid wires were twisted together and connected to the sleeve. The orange striped wire was connected to the ring and the red wire was connected to the tip.

    It's a little ironic, before the mod the level was too low when set to full volume, now it's almost too loud when I have it full down. I much prefer too loud.

    Later,

    My colors were red, black and white. White wasn't connected to the speakers, but was connected to the circuit board in the clamp body. I could get sound by using the black and either the red or the white although the white wire was much quieter.

    If I remember correctly from my manual, the MP-3 player is in stereo...any chance the red & white wires come into play for playing the MP-3 stereo function?

    The Q2 is not stereo via Bluetooth. They will have an A2DP unit later this year (supposedly) but for now, music over bluetooth sounds terrible. I use an FM transmitter plugged into my iPhone and just tune the FM radio in the Q2 to the transmitter freq. Works good enough for riding my bike.

    If you have the docks with the audio input jack it may be wired for stereo. I haven't done one of those yet as the 10 I have on order with Cardo have not arrived. I'm sure it's wired the same though. Pretty simple.

    Great info - thanks biggziff for starting this thread!

    When riding, does the jack flap around in the wind or do you tuck it under your helmet?

    Has anyone tried modifying a dock with the audio input jack? I'm just wondering what color wires you put where. The two wires strands coming from my dock contain; Right speaker - red, green, copper and Left speaker - red striped, green striped and blue.

    As previously stated, it looks like only two of the three wires are connected to each speaker (right - red and green, left - red and blue). I tried, one side at a time, to connect those same wires to the jack with no results (ie. no tone when pressing the vol up and down buttons). After testing different combinations, I got the right side to work using the red and copper colored wires and the left side using the red and green wires. This makes no sense to me. Anyone else have the same experience or know why this is happening???

    THANKS!

    BT

    Sorry I didn't see that thread had come back to life sooner or I would have tried to help you out with the wiring.

    Someone asked about letting the jack flap in the wind? I used velcro. Soft around the jack and the scratchy stuff on the back of the helmet.

    I tuck the jack up between the foam padding and the helmet.

    I just did this mod, and the volume is noticeably quieter than the helmet speakers, even with plugs in.

    The original speaks are 8 ohm and almot every earbud is 16 ohm. Does anyone who has done this find it difficult to hear the intercom audio while riding?

    I can turn the zune volume up and hear it just fine, I'm concerned about the intercom though.

    If you wire it wrong you will lose significant volume level. DAMHIK. With earbuds, I can run the Q2 at it's lowest volume and it's almost too loud.
