Oh boy, here we go again. Third time’s the charm
These high-density tuning foams are great for the DQ6. Essentially the Hana filter, except these are only 2 usd for 20 pieces lol.
The low-density version doesnt really do anything though.
Installation:
You simply remove the stock filter by taking a tweezer and pressing down on it and pull it back up (be careful to not ruin it if you wanna reuse the stock filter). Then drop the tuning foam in the nozzle and press it down so it stays in there.
