Hoping to get a little more info on the differences before I make my decision, but I am considering two models recommended here. One option is to go for the (based on reviews) neutral sound of the Superlux 668B, then get a "fun" option like the Grado SR60i or SR80i later on to compare. However, it may be a while before I get around to purchasing a second pair, and I think I may prefer the warmer sound of the Panasonic HTF600 to start. Plus, it's a bit cheaper after looking for the best price. Or should I hold out for the Grado to start with.
Panasonic HTF600 ($48 including shipping)
Superlux 668B (around $70 including shipping)
Grado 60i/80i (99/129 plus shipping)
Any further thoughts on these 3?
Your profile does not indicate your home country, but those prices are higher than you have to pay in the US.
The Superlux is a great can for money (about $50 here), but it's not really neutral. It's bright with a treble/upper mids spike.
I'd go with the Grado SR 80i (or better Allesandro MS-1i). However, some like (even love) the Grado sound signature and some don't. Also some people have comfort issues with the Grado family cans.
