Ehrlund Microphones is a Swedish manufacturer founded in 2005 by inventor Göran Ehrlund, with design and assembly carried out in Sweden. The company is built around a patented triangular capsule membrane, an unusual departure from the round diaphragms used by most condenser microphones. The triangular shape has no parallel boundaries, which Ehrlund argues subdues resonant standing waves across the diaphragm and produces a faster, more controlled impulse response.

The product line centers on hand-assembled studio condensers including the EHR-M and EHR-M1 fixed-cardioid models, the multi-pattern EHR-T (which adds supercardioid, omni and figure-8 patterns via a dual triangular membrane), the EHR-H handheld, the EHR-D and EHR-E. Alongside the microphones, the company makes the EAP (Ehrlund Acoustic Pickup), a contact-style pickup used on acoustic guitars, double bass, cajón and other acoustic instruments.

Among small-format pro-audio brands, Ehrlund has built a niche reputation in the boutique studio market for natural, uncolored tone and detailed transient response, and the mics have been reviewed in publications such as Sound On Sound and Tape Op. They are sold internationally through specialist pro-audio dealers rather than mass-market retail.

Ehrlund Microphones has 3 products cataloged on Equipboard, including Condenser Microphones.
