Hi everyone, I have posted some questions earlier in this post and the people that replied were extremely kind and knowledgeable and asked me to post some impressions once I got the eq7.
Well here it goes, please consider that I am not a great audiophile so take my impressions with a pinch of salt...
I bought them this morning in Japan, it was a bit hard to find them but eventually the store staff dug some off the stock, meaning that these IEM sold really well here.
I have tried the Turbines, eq7 and the IE8 (here in Japan you can pretty much try everything on before buying) and despite a lot of background noise (biccamera in Japan has speakers shooting out loud a lot of different messages/music), I got convinced that I was doing the right choice.
IE8 are too expensive for me, turbines did not stay in my ear despite a great bass even with no seal at all.
I also bought some M size Sony hybrids to go with them as it seemed that they fit well with the eq7.
Well, what can I say? First impression is totally great. The HF5 that I had before, despite a deeper fit seem light years away from the eq7, on all aspects. When I mounted the Sony hybrids the fit improved tremendously and I have tried them over the ear in the gym (45 minutes workout with the bike) and they sat there comfortable without loosing seal (saving from the last 5 minutes where I have tried to move my jawbone in all possible way to see if they would stay in place, and even then the insulation was really good).
Soundwise bass is what I was looking for, nothing exaggerated (I am not a basshead), but rich and full, just like I like it. Mids and highs are really nice too, maybe I was concentrating too much on the music but I could hear clearly instruments that before seemed a bit muffled. I have tried jazz, rock, pop and some electro-bass music, all were really nice.
To make a comparison I put on the HF5 for a bit and saving from the absence of bass, the eq7s do an overall better job than the ETY.
I am really happy with these IEMs, although I need to test them on the plane and surely the hybrids need a bit of wearing to get the perfect fit, I already like them a lot. Tomorrow I will try them on the trains in Japan, usually crowded and noisy, for a longer time.
I was scared at first that the fact that they do not go "deep" into the ear would mean a worse noise insulation. Well I was mistaken, there is a difference but it's honestly minimal, something that you get used to with time.
So what can I say? Thanks a lot to all the people that gave me advice, it was really a great pick!
