This is my first review on Head-Fi. I don't have a lot of experience, but I'm a guy who loves to try different audio gear. I mainly own open back headphones and IEMs, so the FF3 was my first audiophile flathead earbud. I'll give you my honest, short opinion of these earbuds. I'll only talk about the sound, and I'm using the donut foams because I believe they provide the best balance. It's been nine months with the FF3, and they are incredible. I didn't know that earbuds could have bass this good; bass quantity is not at the level of IEMs, but more...
