The SENTRY HW701 Wireless headphones look like yet another rebranding of those “As Seen On TV” basic RF wireless headphones with a transmitter base that takes two AAs and the headphones taking two AAAs. These are best for utilitarian usage, and not for music listening (unless you just want “background noise”). Regardless, the price is very right in this case, you can get them in “Used – Very Good” condition for $3.16 at Amazon Warehouse Deals.

The usual free shipping terms apply, if you are a Prime member, you can get them in two days for free! Non-Prime members need to place an order of $35+ in qualifying items for free shipping – as usual.
