Free Sennheiser HD 4.20s Over-Ears with purchase of Flex 500 Digital Wireless System for $200 total

It’s a Sennheiser Combo Value Meal! For a limited time, if you purchase the Sennheiser Flex 5000 Digital Wireless Headphone system for its current price of $200, you can get the closed-back over-ear Sennheiser HD 4.20s (don’t smoke them!) for FREE!

To get the freebies, you must have both of them in the shopping cart, and both must be sold and shipped by Amazon actual (not marketplace sellers) and in new condition. Add one of each in the shipping cart:

+ Sennheiser Flex 5000 Digital Wireless Headphone

+ Sennheiser HD 4.20s Over-Ears, closed-back
+ oops, almost forgot, we have a text and pictures unboxing here of the HD 4.20s headphones (no annoying audio/video)
+ so mayhaps there is a method to this bundling madness, because the HD 4.20s’s best feature is perhaps the earpads, comfort for long TV viewing/listening sessions

Then proceed to checkout, and at the top right corner of the Checkout page, the current price of the HD 4.20s will be automatically discounted. there’s no coupon code to enter. If you don’t see the discount, it means the promotion expired or something else is wrong. You must see the discount, otherwise you won’t get the discount!

Here’s a screenshot of how it should look:

What the Frell is the Sennheiser Flex 500?

The Sennheiser HD 4.20s is part of the Sennheiser HD 4*.* series, a known entity. But what exactly is this $200 Flex 500 digital wireless headphone thing?

This is based on the product description, I haven’t seen this: it is a more stylish wireless audio system, that is not using Bluetooth, so it is an RF wireless. It has digital optical and analog inputs. The receiver has a built-in rechargeable battery. The transmitter is more stylish than the usual pucks and headphone stand style transmitters of old. It looks more like a stylized doorstop 🙂

You can use any headphones with it, it has a 3.5mm audio port. Included in the package are the MX 475 earbuds [check their product page]. These come standard inside the Flex 500 box.

Since the Flex 500 can take any 3.5mm headphones, the limited Sennheiser promotion is giving the HD 4.20s closed over-ears for FREE since some people may prefer full-size headphones instead of earbuds. You have to manually add the HD 4.20s in the shopping cart to get them for FREE. The MX 475 earbuds come sealed in the Flex 500 package – you don’t have to do anything to get these (other than buy the Flex 500 item).

Note that the Flex 500 is targeting TV viewers. If you are interested in using this for music listening, there are trade-offs to consider versus other wireless audio options, and some of that may depend on exactly where you are planning to use it (RF interference, etc).
