Is this a genuine pair? I didn't think the bag would have anything important so I threw it away. It does however have 2/3 of the same number with 13(W)27 and 1327 in the serial number. Good thing I kept the tag on the wire
As for weight, I don't have any means to accurately measure it. Using a dingy scale, it measured in at ~0.4 ounces. Putting a penny(0.088 ounces) along with it on the scale put it at 0.5 ounces, so I'd estimate its around 11 grams? This was measured with the stock turquoise tips on
Here’s a tip on the weight, if you walk into any jewelry store, coin shop, or any store that “buys gold or silver”, they will have a super accurate digital scale. They will weigh it for you for free (it literally takes 2 seconds). Ask them to weigh it in grams (with stock tips on).
Getting an accurate weight is one of the best ways to detect a fake (other than opening a shell up and examining the driver of course).
So it’s up to you what you want to do: check the weight or pop it open and look at the driver. The shell pops right apart if you separate it at the bass vent hole on the top of the shell.
For the driver test, the easiest way to tell is to look for 2 small round solder dots on the circuit board. This is an odd and unique feature I’ve never seen on an IEM driver before. So it’s a dead giveaway to a genuine driver.
You can see the 2 round solder dots in this photo:
The fake drivers have no such dots:
The vent tuning paper (black fabric with the white oval hole in the center) is also different. On the genuine Sony driver, the tuning paper is ridiculously long (covering exactly 1/4 of the driver’s circumference). This is another oddity that’s unique to the Sony drivers. Most IEM drivers look like the fake one, which have a very short tuning paper.
So there you go. Between the tuning paper, 2 round solder dots, and an accurate weight, you can easily identify a genuine from a fake.
