- Top model of the Lambda series
- Open-back over-ear headphones
- Detachable connection cable
- Frequency response: 7Hz - 41kHz
The transducers in the Lambda SR-L700 MK2 are even higher quality than those in the Lambda SR-L500 MK2, and are even more closely related to the transducers in the flagship model, the STAX SR-009S. If you want to experience a touch of absolute luxury in headphone construction at a comparatively affordable price, the STAX Lambda SR-L700 MK2 is a must-have.
All STAX headphones and in-ear monitors are electrostatic headphones operating on the push-pull principle. Due to their operating principle, they require a STAX driver amplifier to function.
Design:
- Black surfaces
- Leather-covered ear pads
- Comfortable headband adjustment in ten increments
Technology for excellent sound:
- Detachable connection cable made of silver-plated, long-crystal, oxygen-free 6N pure copper (OFC 99.9999%), with extremely low capacitance
- Gold-plated connector
- Recommended driver amplifiers:
STAX SRM-D10 (for mobile applications)
STAX SRM-006tS, STAX SRM-D50, STAX SRM-727 II, STAX SRM-007t II, STAX SRM-700T and STAX SRM-700S
Note on operating voltage (bias voltage) of STAX headphones
Many early STAX headphones are designed for an operating voltage of 230V/DC. However, the headphones of the PRO series - which includes all current models - require a higher operating voltage of 580V/DC.
In the past, STAX offered driver amplifiers that provided both operating voltages. The 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.
