First is the tips selection. Optimizing the spacious large sound and how it projects to your ear I have used the community favorites. Spiral Dots, Symbio Peels, a variety of foams and such. I recently decided to try these.
These are Azla SendaEarfit light tips. These give a horn like effect in your ears due to the wide large opening but more proper than even Spiral Dotss. The stem part I am a huge fan of as it is a stiffer material than the cap. Making these much more verstile on your earphone collection. In a nut shell these fit better on more phones than the Spiral dots due to the stem. Absolute superb open sonics using these. They basically amplify the sonic quality you enjoy about the H40 to be even bigger more spacious sounding than standard tip. Highly recommended as they come 2 pairs for $13 for whatever size you need.
The Azla SendaEarfit light tips are little miracle workers for me on my Blon 03's. So far they give the best overall performance. I've never really experimented with different tips but the way the blons fit clearly something had to be done. Mine came with the SpinFit copy tips but they were too shallow and didn't work well for me. I tried SpinFit CP500 and regular Spiral Dot's too. Just too damn shallow. Spacer mod, tried that too. It amounted to nothing. All the foams I tried just left the bass thick, the mids a bit muddy, and they killed off the highs that gave the impression of air and space.
I usually wear a MED but decided to try an inbetween size ML Azla SendaEarfit with the standard material. Compared to the foam tips the EarFit's stayed put in my ear and much of the higher notes and air that the stock tips presented were still there. As a bonus I was now getting a bit better, tighter bass.
After a few days of on and off listening my ears started to hurt a bit so I decided to try the same tips in my normal smaller M size.
I thought the smaller size was better for comfort but there was something else going on here.
Just by going to that little bit smaller size the notes seemed to be a just a little crisper, cleaner, somehow more whole and the bass still had it's slam. My hurting ear got me to thinking about the Light version of those tips. Yea, I ordered those next in the same size. However I couldn't forget what I thought had happened to the music when I went to the smaller tips so I also ordered the MS size for crap's and giggles.
When the Light tips in M and MS got here I tried the M version first just to keep the differences small. They seem more comfortable to me so I listened to a couple of songs I really like that have some air and space to them. Joe Walsh- The Confessor, Billy Thorpe- Children Of The Sun. I also played a couple of Rush tunes (Red Barchetta & YYZ) to see what Neil Peart was going to sound like when beating the hides. For me his kit never really sounded tight enough with the blons, always a bit thick. Overall it seemed just the switch to the clear silicone material had somehow taken a little of the drum and bass bloat/ thickness out and also added just a shade of highs. The M size still fit and sealed (at times they turn inside out when I remove them) the low note of the drums and bass guitar were still there when called for.
I installed the MS size and it seemed once again things tightened up a bit. I think I'm getting a cleaner, less muddy sound with even more of an air quality to it during those first two songs I mentioned. But the kicker is during the Rush tracks the drums and bass seem so much cleaner but yet they retain their weight and impact for me. It's just that now the men behind the instruments are starting to show through a bit without making the blons overly technical and retaining their fun sound.
I'm thinking either the smaller size is allowing the tip to be inserted a little deeper -OR- the larger sizes were actually presenting a smaller opening because they were being somewhat crushed/ deformed in my ear canal. While good for a seal, not good for sound. I tried swapping back and forth several times and it's either a repeated convincing placebo effect or I have found my perfect fit with the Blon 03's.
So yea, what the hell, I ordered the small EarFit Light's yesterday. I don't have them yet but I really think the MS size is THE ONE for me.
Don't know, maybe with how specific you can get with the between sizes the EarFit's offer I'll end up with a different size in each ear.
Yes I've clearly spent more than what the blons cost just it tips. To be honest I purchased a Tripowin C8 cable at the same time as the blons so....
But hey, there was no way I was going to end up with the sound that I'm hearing now without some experimenting.
Experimenting is half the fun for me.
