SO,
After 2 weeks of use, one my units is partially dead. Not sure what happened.
2 days ago I was riding to the gym, and I got a call which was automatically answered by the intercom. It worked just fine.
Rode back home and jamming to some tunes - no issues.
Yesterday, I was riding to the gym again and received a call. The device automatically answered the call again (like normal), but the person on the other end could not hear my voice at all - not even static.
Anyway. Got home and tried everything, including different headsets with MICs...still nothing.
I figured it wasn't worth shipping it back to get it replaced (GoodDeals88 offers 2 years warranty on these), so I decided to tear the sucker open and see if it's something obvious.
After opening the case, the headphone jack just fell out. It was very, very poorly soldered on.
IT's hard to make out in the pics, but the soldering job around the little chips is quite bad. It's almost like no solder was used, so a minor flick of the finger may break the solder loose.
I ended up soldering the headphone back onto the board thinking that will solve the mic issue.
Back to square one. Everything works great,
except the intercom (only reason I bought the unit).
While the soldering job and overall layout of the board looks pretty crappy, I was impressed with the rubber housing/case. It took quite a bit of effort to rip it open. Again, it's hard to make out in the pic, but the rubber is actually quite thick and completely sealed. The only place I can think of that water would get in is the headphone jack/USB port area.
The only thing I haven't tried is pairing it with another phone to test the mic. It was working fine with my iPhone, so I suspect it's a hardware issue.
