Hi I'm fairly new around here but I was wondering if I could get some input on the amount of bass the a4 has. I'm asking not because I want allot but because I'm worried it might be too much for might taste. My reference iem's are flare audio r2a and r2s as well as audio technica im70 (which I find had way too much bass these days). I also own the over ears akg 712pros which I love. Any thoughts would be much appreciated.
I do not have your IEMs for a direct comparison regarding the low-end frequencies. One of the strengths of the A4 is that you have three tuning filters for the low frequencies. If you find too much on the low-end you can adjust it easily and get a very nice altered bass response.
The red filter provides the most low-end range.
For a lot of people around here the black filter which has a little less on the low end frequencies to be the sweet spot.
The blue filter provides even more reduction in the low-end Which maintains a tight controlled bass response allowing nice mid range and higher range frequencies to shine with the correct front filter
One comment I would like to make about fit that I have found in my personal experience. The ear tips are use over the ear versus down can make a difference for isolation and fit.
I find down my spin fits give a better isolation and seal and it requires more tinkering for me to get nearly the same isolation if it's worn over the ear
