Thanks for the deal OP. I also grabbed the SOL Republic Master Tracks Headphones as well as I could return them with eBay plus if I didn't like them.
After using both, the sound quality is definitely better on the Sennheiser's - which may be a bit evident due to the price difference. It is $22 more expensive but the bass is stronger. I'd recommend the Sennheiser's over the SOL Republic if you're on the fence.
Doesn't match up my daily driver earphones though which is again, a different price range (Razer Hammerhead Pro v2 - $100).
