I have had my 65t for exactly a month now. I have travelled extensively throughout this past month and have used the 65t in airplanes (10 times), railways (1 time), subway / metro (multiple times), cars (during long distance drives), 2 different gyms, home, and office. I have noticed that the connection is perfect everywhere except in the following places:
- In my office cubicle, which is right in the middle of the building on ground floor and is infested with 12 different wifi routers and 2 different cordless phones sitting next to me. Here my left earbud keeps disconnecting no matter what position my head is in. No issue for me as I don't wear it while I am in my office.
- In the subway (metro) but ONLY when it is running underground AND I am sitting next to the window, the left earbud keeps dropping connection and I have to tilt my head in multiple directions to figure out in which position the connection remains. While underground and when I am sitting in the aisle seat or standing in the aisle, the left earbud only occasionally drops connection (once in a minute or so). When the metro is running above ground, the connection remains rock solid. I now don't sit next to the window.
- Once during a flight, when I was sitting in the exit row, next to the window, I noticed that the left earbud started dropping connection for a brief period of 10-15 minutes. No idea why. Maybe a lot of people around me started using their bluetooth earphones around that time. This has only happened once and that too for a very short period of time in the last 10 times that I have been airborne.
I replaced my UE Super.Fi 5 Pro that served me for over 10 years with the Bose Soundsport Free before settling for the Jabra 65t. And although the Bose SSF had much superior sound quality compared to the 65t, that sucker was dropping connection left, right, and center to the point that it was completely unusable. I tried 2 different sets of Bose without any luck. Jabra 65t on the other hand has been completely trouble free 99% of the time and I have now learned to live with its slightly muddied sound quality.
