- Spacious, open sound
- Open over-ear headphones
- High wearing comfort and low weight
- Frequency response: 7Hz - 41kHz
With the STAX Lambda SR-L500 MK2, technology derived from the STAX Lambda SR-009/009S (such as the more elaborate cable technology) enables an even more spacious and refined reproduction compared to the STAX Lambda SR-L300. The materials are also of higher quality, and the wearing comfort is correspondingly better.
All STAX headphones and in-ear monitors are electrostatic devices operating on the push-pull principle. Due to their operating principle, they require a STAX driver amplifier to function.
Features:
- Black surfaces
- Ear pads covered with synthetic leather
- Comfortable headband adjustment in ten click stops.
Technology for excellent sound:
- Detachable connection cable made of oxygen-free high-purity copper with titanium admixture (HiFC™), with extremely low capacitance
- Gold-plated connectors
- Recommended driver amplifiers:
STAX SRM-D10 (for stationary and mobile applications), STAX SRM-353X, STAX SRM-D50 and STAX SRM-006tS
Note on operating voltage (polarization voltage) of STAX headphones
Many early STAX headphones are designed for an operating voltage of 230V/DC. However, the PRO series headphones - which include all current models - require a higher operating voltage of 580V/DC.
In the past, STAX offered driver amplifiers that provided both operating voltages. Current driver amplifiers only have connections for the higher operating voltage of 580V/DC.
To avoid confusion, the connection sockets for the different operating voltages are designed differently.
