2x STAX SR-Lambda Signatures

Both are functional but seem to have slight buzzing in the drivers due to I believe dust. One has a silver driver and one has the black standard driver. Both seem to have stock pads, stock cables and chassis are in good condition. Both Lambda Signatures are sold AS IS.

Lambda Signature (Silver Driver): Does not seem to have any channel imbalance. Left side has a tiny bit of buzzing, most likely caused by dust as I can't hear any other problems. There is a bit of buzzing on the right side. Overall functional. Sold as is. $300 shipped.

Lambda Signature (Black Driver): I believe the left side is a bit quieter. There is also some slight buzzing in the left side, most likely caused by dust. Right side is perfectly fine. Sold as is. $300 shipped.

Both pairs are overall usable and the buzzing is not really noticeable when listening to music. Channel imbalance can be "fixed" via something with a balance knob like the SRM-T1 or SRM-1/mk2.

$550 shipped for both headphones.

Will be shipped via UPS. Prices are OBO.
