The closed-back on-ear portable Beyerdynamic T51i headphones are currently available in “Used – Very Good” condition described to have minor cosmetic imperfections and damaged original packaging for $173~ with free shipping by Amazon Warehouse Deals actual.

Always check who the available sellers are, don’t just look at the price over there. AWD actual is part of Amazon, so you get Amazon Customer Service, fulfillment by Amazon (Amazon’s shipping service and returns, so Prime eligible), and their 30-day return window. Amazon does not make any claims of warranty offered with the product. A number of authorized dealers selling open-box items through AWD though state in the individual listings that their open-box items get warranty. So YMMV if want to claim warranty service from an AWD actual purchase.

This is a promising listing if you have the patience of wait and see. Currently there are four separate “Used – Very Good” condition listings by Amazon Warehouse Deals actual on the Beyerdynamic Custom One Pro Plus headphones for $121. Condition is slightly different per listing.

Strategy: since there are four listings and this is not a mass market model, if no one buys them, there is the possibility of supply putting price pressure on demand and prices dropping further down. Their new condition price is $200 for the black color scheme which is what these are. They average 4.3 out of 5 based on 56 customer reviews. These are customizable in many different ways, but Beyerdynamic is not really advertising them, so they don’t have the average consumer brand awareness that other models have. They are closed over-ears.

And now a potentially interesting used find, the black color scheme of the closed back on-ear Beyerdynamic Custom Street headphones, with their “custom slider” go for $150 in new condition but if you are comfortable with Used, you can get them in “Used – Very Good” condition (minor cosmetic imperfections, damaged original packaging) for $93~ with free shipping by Amazon Warehouse Deals actual.
