I did the close vent mod as suggested by @HiFiChris. Bass quantity has definitely increased although not by much. As far as I can tell, mids and treble aren't affected by the mod. With the increased bass brought on by the mod, these Gen 5 hybrids do sound better now. Currently enjoying listening to them using some silicone tips that I got with my **** 4in1, these tips don't have a wide bore but the length of the bore is a bit longer than the stock tips. If you take a close look at the stock tips when they're attached to the earpieces, the nozzle is very close to the bore of the eartips. This could be a reason why they sound the way they do OOTB. As a sdie note, this require a volume setting of 65 on my Fiio X1 for a good listening level, higher than most of my other IEMs.
However, I wish to talk about something that's been barely mentioned here. It's about the strain relief. IMHO, the strain relief is just adequate, not good and definitely not great. And this is at all major points, i.e.at the 3.5mm jack, the Y split and the joint of the cable to the earpiece themselves. I wish Xiaomi/1More provided better strain relief all around.
Also, as someone mentioned earlier, sound isolation with this Gen 5 hybrid is pretty bad. I'm sitting in my local Starbucks right now and with the music turned up all the way to 65 on my Fiio X1, I can still hear people talking all around me. It's just very slightly better than the isolation I'd get from using Monk Plus earbuds. Definitely don't use this for a noisy/busy commute.
