Sennheiser HD660s

Sennheiser HD660s Introduction

For Sale: Sennheiser HD660S – New, Used for 3 Hours Only! I’m selling my Sennheiser HD660S headphones. These are practically brand new, only used for 3 hours. While they sound amazing and have a detailed, balanced sound profile, they just aren’t the right match for my personal preferences. I already have a couple of other headphones and IEMs that I use more often. Bought it, opened it, listened to it, back in the box. Condition: Brand new, only used for 3 hours, excellent condition. Why I’m selling: Not the sound profile I prefer, so I’m letting them go at a great price. Price: $315 – My loss is your gain!
