Ive had these for about 9 months now and they have served me well. They are comfortable and the audio quality is highly satisfactory. The battery life is also impressive for both the device and its transmitter. Unfortunately, they are slightly frail for my usage, i found that the plastic loop around the back produced a small hairline crack around the back from useage with my head lying on a pillow. This has been repaired and strengthened with glue yet it is mildly disappointing that this occured.
