I am very pleased with my Pill, it has a very nice sound and I can hear everything very clearly. The Jambox and Big Jambox that I used in the past weren't nearly as crisp sounding and I was running high-quality mp3 files through them. The Pill can also pump out a decent amount of bass depending on the quality of the file and the final mixing of the song. If you're looking for a lot of sub bass, you won't find it here, but I find it surprisingly deep on many occasions. My only qualm is that it does drop the Bluetooth connection every once in a while, but it does have AUX in/out inputs. Other than that, I really enjoy this thing!
I have a Bowers & Wilkins Zeppelin which is phenomenal. I was looking for something portable with good sound. Of all the products I bought and tested, this product by far sounds the best for the portability. However, I cannot get it to work with iPhone 5 and it loses connection with my iPhone 4s following my ios 6 upgrade. I understand that someone is working on it, but I am not sure who or how. I am beyond my return date, so just make sure you try it before your return date runs out!
