I have been using he nokia bh 503 headset from 3 years now. It is surprisingly running seamlessly. The sound quality is quite good when you compare it to the other headphones. Plus this headphone is pretty economical too. The main USP of this headset is the sound volume. It can get really loud. Obviously at the expense of sound quality.
The base of the headset is pretty good and the low tones are also clearly visible. I travel by train daily and this headset is my faithful commuter. I really like its noise cancellation feature as well. Having said all this there are a few negative riders as well. The market is now full with cheap copy products of this piece, so if you are planning to buy please be aware. Second the ear gripper can hurt you over a prolonged use if you have even slightly hard ears. And the third or the most depressing thing is that the battery performance significantly deteriorates over time. Earlier I used to charge it fir 2 hours and it could easily play a nice 7 to 8 hours.
But now it vice versa. I charge it for entire night and it hardly lasts for 3 hours of playtime. I believe all electronic products deteriorate but this one deteriorated a bit too fast
