Can not comment on the TDK but can tell you what I use with great success and sound clarity.
If you have a quality pocket clip on FM radio and a set of good ear buds this is an inexpensive home run for you and there is NO delay
This is the transmitter

This is one of the radios I use (all the time as it has very good reception)

These are the phones I have (actually have 2 pair the i6 not made anymore and these)

Caveat of the transmitter is the battery self discharges in about a week. I bought 2 name brand (Nokia) batteries (under $5 each) that hold up much longer (have 2 transmitters)
Once charged you can get a full day of use with no problem on level 1 output. Sometimes when the battery drops to 3 bars you have to bump up to the level 2 of output or you get some break up when you walk away from the MD.
One last thing, the usb charging cable ( real cheap one) they provide failed on me and some other customers, so if it does not charge, grab a cable out of the usb spaghetti box we all have in the closet.

You can check the reviews of the transmitter on amazon, they are on the money!
Sorry for the huge photo..
