Question Knock-off Sennheiser SR2050 IEM Sounds Tinny?

I caved and purchased one of those knock off Sennheiser SR2050 IEM units on ebay, this one to be exact:

SR 2050 dual Channel UHF Wireless In Ear Monitor System for Stage performance | eBay

I'm using it for my wedding in a month, so needed something quick and cheap. I had thought about going the DIY FM transmitter route, but they don't offer a lot of range most of the time. I don't have any huge complaints, other than that it just sounds really... tinny? Things are loud and come through clearly, but it seems like the EQ is severely lacking. It's mostly in the bass & mid range on the spectrum.

Will be running a band through Ableton, with each player having their own in-ear sends. Haven't tried it yet, but thought I might EQ each individual send channel and see if that offers a solution. Seems plugging my ears straight into my interface prove that the EQ comes through clearly.

I mean, I have a pretty good idea on what I'm getting into with any sort of cheap equipment. Is this just isolated to the capabilities of the unit? Any other thoughts, possibly?

Thanks!

Westone UM Pro 20's on my end, but I'll use your suggestion and try some others. Hadn't thought of that. Thanks!

Your description points to there being something not-quite-right in the compatibility between the transmitter and the receivers . . . like different pre/de-emphasis standards and/or the companding (noise reduction) mistracking. It's not unlikely that such a kit was put together from contract-manufacturing surplus pieces, and the fact that they merely pass audio was considered good enough.

I think the most pragmatic solution is simply to EQ the audio feed to the transmitter until it sounds acceptable.

Yup.

Ear buds will tend to sound as the OP describes. It usually takes a custom molded set to get enough of a seal to get good low/mid response. EQ will only go so far, but it's a good start.

Often cheap iems ship with $2 earbuds. I have a cbinese iem which is ok, save for the earbuds that got binned.

If you already have good ones, my advice is moot.

Thanks for the reply, guys. I ended up EQ'ing the crap out of it externally, and it sounds now like a normal wireless system. My problem now is the volume fluctuations. Testing different songs, it's like the limiter either hits too hot, or is fine. Any advice? Should I try boosting the RF signal, or is that pretty normal for something like this?
