Seems a great deal on these open back headphones with great reviews all around. I believe this is the cheapest they have been on amazon.
Like all the 'Prestige Series' models, the multi-award winning* Grado SR80e is an open-back, on-ear design. It is light, comfortable and built on the same features as the SR60e headphone. However the SR80e utilises a 4 conductor connecting cable and the driver diaphragms are put through a special 'de-stressing' process in order to enhance inner detail. The result is a headset which delivers a wider, more open and dynamic soundstage, but which is also smoother in the treble and deeper and even better controlled in the bass; a sound that is pure Grado.
The SR80e is an open back on-ear headphone. The jack will fit into any modern day Hi-Fi system or music source, so that you can listen to music from any source you desire. The headphone is fitted with 3.5mm jack. A 6.33mm (1/4”) jack converter is included (fitted to the 3.5mm jack).
