I have a set of
Kinivo on-ears that are fairly neutral; they're rechargeable via USB but they don't push a huge amount of level. Battery time is pretty good, though, about 6-10 hours depending on the bass content/listening level. They're also not too goofy looking, and no antennae that make you look like My Favorite Martian. They're Bluetooth and certainly capable enough for overdubs; I've only mixed a few tracks with them but they translated very well.
I also have a compact wireless FM transmitter (runs on two AAs) with about a 100 ft range; (the Bluetooth says 35, but it's more like 20) you can use any self-contained (meaning they have an onboard tuner) headphones that receive FM. Some cell phones can receive FM, and that works too, with some earbuds. Due to FCC regulations, it's kinda hard to get a very hot signal without using multiband compression upstream from the transmitter, but it did work, in a pinch, for a tracking session where I had musicians located all over the joint; both bedrooms, the bathroom, the garage-but I certainly wouldn't trust it for mixing.
The Sennheisers in your link probably do a much better job; I wouldn't be afraid to try 'em, at that price point, IF they're digital. The trouble with FM is the trouble with any non-digital wireless system:
companding circuitry, the quality of which can vary greatly. You can't make valid decisions about levels, EQ or compression, when you don't know what your wireless is adding/subtracting.
