Just my 5 cents.
@Jackpot77 reviewed the IMR R1 on
www.audioprimate.blog
He owns Empire Ears Zeus and Athena, CA Vega (and Andromeda too I think?) and the Trinity Phantom Hunter (by way of background intro and frames of reference for those who don't know).
He described the R1 as being hugely enjoyable, very smooth, warm and organic.
Detailed but not a micro-detail monster.
With these kinds of qualities, it would not be surprising if the IEM was able to smooth over the deficiencies in compressed/lossy formats or lesser-quality masterings.
I don't think it's straightforward to have a definitive paradigm where TOTL IEM = exposes poor recordings.
It depends on the sound signature of the specific IEM.
I think my Hunter/PM4 'expose' poor recordings more than my Noble Katana, for example.
Finally, regarding the tuning being all over the place (or whatever the criticism was, I forget the exact words), he could be right.
But, that doesn't necessarily make it a poor IEM.
The tuning of the Vega by all accounts is pretty weird and it's certainly not everyone's cup of tea, but other audiophiles rave about it.
My understanding from hearing what sound engineers have to say on the matter is that generally in an IEM, they're naturally looking for the most neutral, reference sound signature possible to aid them in their work, and to match what they are used to dealing with.
To someone who's used to hearing and working with such a sound signature, any U-shaped, L-shaped or other tuning would undoubtedly sound weird, skewed and possible even repulsive.
I'd been listening to a neutral, reference style DAP for a couple of months pretty much non-stop, then tried the Sony WM1Z at CanJam.
My reaction was exactly "UGH!".
Looking back now, with more knowledge and experience of different sound signatures, I was just unused to (and unprepared for) such a rich, thick, warm, organic sound signature. If I had time to listen to it extensively now, I'd probably think it was amazing.
So the fact that a sound engineer thinks that a heavily warm and organic IEM sounds weirdly tuned is not necessarily unsurprising or a negative.
In my opinion, it doesn't casts aspersion on either the sound engineer's taste, expertise and discernment, nor on the IEM itself.
Personally, I'd love to hear the R1. Based on what I've read about it, it's undoubtedly not a giant-killer or world-changer, but could well be a good, solid IEM for the price, with some less common features (interchangeable filters, open/closed vent option, dual dynamic drivers, etc).
For those for whom it ticks their boxes and who have the funds available, a decent buy. Nothing unworthy in that.
I don't know the truth of the Bob/Trinity story. It may come out in time or not.
I bought some products, cancelled some others, and am still waiting for another.
All I can say is that there have been some very positive reviews of the R1 and, it would seem, some negative ones too, and this is to be expected for any new IEM that isn't being overhyped, especially one with a very specific, somewhat polarising sound signature.
And people have been receiving them within the deadlines promised.
Whatever the facts are regarding Trinity and Bob's role in it, I personally am a firm believer in second chances (I appreciate others may not share this view) and, thus far, I think IMR/Bob have been blameless in their conduct and the quality of what they've put out. You can't ask much more, and hopefully it can continue like this.
