Do what I do, I have a tablet in front of me for watching movies/shows and have that connected via bluetooth headphones. Can't hear what is going on with the beeping noises the Direto makes (or Trainnerroad running on my phone for that matter). But I can still hear the trainer noise and the fans around me. Definitely a bit louder (not by much) so far than my Fluid2 trainer though.

To ironmantee, I chose the Direto over the Flux because of people still posting on the FB Flux group of issues with their units (a guy just had his 3rd unit fail and had to be sent into warranty again....Units 2 & 3 for him were warranty replacements - this was last week). I know they only post issues but even after 1-1.5 years of the Tacx Flux being out and still people complaining of units dying is a bit off putting for me. I thought about the more expensive ones like the Kickr, Hammer, Drivo and Neo but couldn't justify the extra costs (since I don't plan on Zwifting for now and other similar type of road feel apps). So my choice was Flux or Direto instead as I wanted a smart erg capable direct drive trainer. That reliability issues still for some along with the fact that the Direto has a real power meter in a sense with a higher grade simulation was the final factor in my purchase.

I've used a computrainer 1 time but can't recall how different it felt for controlling in erg mode. But it was definitely quieter than a Direto. I still have to get used to Erg mode though as I was putzing around with gears and it took some time to get up to the target power (was doing trainerroad Ansel Adams -1 with VO2 max intervals at 130% ftp). Need to just try and stick with a cadence in a lower gear it seemed to help a little better but harder than my Fluid2 so far to hold the target power a bit more consistently. I also discovered my phone may not have the bluetooth support to control the trainer (have to look into that more) and had to switch to the Ant+ to get erg mode to work.

Also, to others, when you did a calibration (if you did one), were you close to the factory offset? I finally did one this morning after my Trainerroad ride and was about 21 points lower for my calibration. Couldn't get the elite app to set my power smoothing either (kept failing). Might have to mess with it later when I have more time. Seems from brief testing the Direto reads higher than my power meter (Power2Max Type S currently connected for now).
