^ Yes, it's just a green filter.
Phonak PFE PB is available on
this site for 80 GBP. Same as PFE1XX series, except with minimal packaging and green filters.
@bublez,
YMMV = Your mileage may vary.
Ultimately the fit and seal in an IEM comes down to the individual's ear - shape, size, bends, oddities etc.,
I am using PFE with grey filters, which give it a balanced sound. They also shipped with black filters, which are supposed to have better bass - never tried them. I'd say it's bass, even with the grey filters, is good enough for me. It has quality (clear and not intruding upon mids), but it does not have the slam / punch you might expect for electronica, hip-hop etc., Sometimes, with a good seal on odd days, I feel it has enough bass (enough quantity), on other days not. It's much like RE-0 - a bit on the analytical side. But, it's mids are forward just about right for my taste - not in your face, not recessed. Soundstage - I'd say is normal. Though I've not done proper A/B, I'd say that RE-0 does well in one dept - I can hear each pluck of the guitar in an acoustic passage. However, PFE trumps it on being easier to drive (RE-0 does need an amp to bring out it's best) & better to use (no microphonics). Sometimes, I felt that sibilance is more (the sibilance is present in the recording itself) with PFE than RE-0, though I am saying this based on my subjective, forgetful audio memory.
I got it from
null-audio, Singapore. He ships to India, though it might cost an additional Rs. 700 or so last time I checked. He also stocks the original PFEs, which have this issue of breaking up under sweat (mine is one
). But then, he is just a student
(Currently, they are all out of stock)
