I purchased a Wowee One a few months ago, and while the bass was jawdroppingly full, the midrange and treble performance was like listening to a portable radio - OK, but not Hi Fi.
So when I read the Foxl2 reviews, with a 30 day money back guarantee I gave it a go.
The Foxl2 synced quickly and easily with my iPhone4. Most other reviews comment on the slight dip in Blue Tooth quality, and the lower maximum volume (95db) on battery compared to using the mains adaptor (97db). In everyday listening there is little between Blue Tooth/line in and mains or battery for volume or quality. Mains powered, using the line in gives the best and loudest sounds (before distortion sets in).
The Foxl2 did benefit from a little running in and a full charge to sound at it's best. I'd suggest a 4-5 hour charge and 1 hour of running at volume to then hear it at it's best.
The Foxl2 has surprisingly good midrange and treble and reasonable bass... for it's very small stature.
So, I connected my Wowee One to the subwoofer output of my Foxl2, after a little experimentation and settling on the Bass Reducer EQ for the iPhone4, the results were amazing.
Great bass, midrange and treble by any portable or boom-box standard.
Neither are Party Animals, but perfectly capable as travel Hi-Fi or for background listening. They will distort at maximum volume... and that would be missing the point, at reasonable volume this portable if expensive combination is wonderful.
I did experience intermittent buzzing, however, at reasonable volume levels the combination of the devices is simply magical.
I won't be needing the 30 day money back guarantee and both units appear built to last a long time.
A great talking point with friends and permanent travel buddies.
