General buying tips for headphones- as I have a lot of headphones from different places, here is my take on how to save money on such purchases. Massdrop- good for collaborations- hd6xx hd6xx akg7xx koss esp95x, these are the best value because they mimic or improve on existing models for generally half or less of the MSRP. Then you also get things like special sales where massdrop pricing is lower than Amazon for example, but you have to wait.
Sweetwater, zz sounds, crutchfield, headphones.com, audio46, hifi heaven, Amazon warehouse deals, adorama, thomann USA,: all these places to bstock, open box or used.
Generally the open box or bstock carry the full warranty, while the used carry 6 month, however Amazon warehouse is just 30 day. I have saved 10-30% off doing this.
Also the music type stores and headphones.com have credit offers often at zero percent for up to 48 months.
The best deal I found was adorama through Amazon, the he560v2 (adorama exclusive) for $200, including balanced xlr cable, excellent plus condition.
Hope this helps.
