I've noticed that there are now some cheap IEM sets being offered, e.g. 3 body packs and transmitters for around £130. I expect the earbuds supplied will be mostly useless except for use with an iPod - i.e. not sufficient quality, bass, or isolation, but does anyone have experience with these cheaper units in terms of the general sound reproduction and reliability after the earbuds have been replaced with better quality items, but still in the £50 to £100 range for each set of earbuds?
P.S. This is in the context of high on stage volume levels due to loud acoustic instruments. I haven't measured it, as I don't have an SPL meter, but loud enough that everyone already wears earplugs.
Our guitarist turned up at rehearsal today with a set of these,
Invalid Link Removed Transmitter and 3 body packs for £120.
The earplugs are not brilliant, I have trouble with earbuds so used my own and now they at least stay in. The other 2 didn't seem to have a problem so I put it down to my strange shaped ear canals. Mine now seal quite well and the bass is significantly better over the stock earbuds.
Isolation with the stock earpieces is not very good. We are not loud so this isn't a problem, in fact it is a bonus as we only have vocals, a small amount of kick and the guitarists C9 organ pedal in the PA. So need to hear the guitar, bass and most of the drums.
Quality seems ok although I don't have anything to compare them to. These are the first I have used.
Range isn't too bad, I went to the bathroom and I was still getting a good signal through several brick walls. I could get it to loose signal (in the bathroom) by turning my body and putting my hand round the aerial. Not something I would do on stage but I just wanted to see if I could get it to loose signal.
One thing that threw us was that they are stereo and we only had a mono monitor output so used the headphone out for today's rehearsal. I have now soldered up a couple of mono to stereo jack to jack leads.
Overall impression was good and certainly worth the price. For our band they seem as they will be perfectly adequate. I suspect this will not be the case for everyone.
Our drummer (the old grumpy guy in the band) was dead set against them but as he has used my monitor (which I schlep) for the past 2 years I told him that if he didn't use the IEMs then I was going to give him my monitor and he could schlep it. He reluctantly tried them and after a few songs declared them a success.
Listening back to the rehearsal recording the vocals are much better (we all sing lead and backing vocals). We usually have trouble with the drummers monitor feeding back because the poor old bugger is going deaf (50 years behind a kit) so needs it pretty loud to hear it. As a result his vocals were often flat even at lowish volume rehearsals. Today the improvement was remarkable.
Summary (TL;DR) They will not be for everyone but for our band they look as though they will work fine. I will update if necessary after Saturday's gig.
