Questyle Pochette SIGMA PRO black leather
Questyle SIGMA PRO Black Leather Case
Questyle’s Sigma Pro, with its aeronautical-grade aluminum chassis and Kunlun glass panels, is a fragile object despite its apparent robustness. The perfectly smooth back surface slides easily on a table or in your hand. This black leather case was developed to address a real need: protecting a device which, at 330 grams and in a format close to the iPhone 16 Pro Max, deserves a case worthy of its high-end finish.
Precision fit for the Sigma Pro
The case matches the exact dimensions of the Sigma Pro (155.7 × 85 mm). It is not a resized generic cover: the cutouts correspond to the locations of the USB-C ports, the 3.5 mm, 4.4 mm, and 6.35 mm headphone outputs, and the side controls. The power button, volume dial, input selector, and gain switches remain accessible without removing the device.
Attachment is based on integrated magnets that hold the Sigma Pro in place without adding any bulky fastening mechanism. The device can be inserted and removed in one motion, preserving ease of use while on the go.
Leather as a discreet shield
The Sigma Pro’s Kunlun glass, as spectacular as it may be with its view of the internal circuits, accumulates fingerprints and micro-scratches over repeated handling. The leather of this case forms a barrier against these everyday annoyances without hiding the visual identity of the device.
The material thickness remains modest. With its case on, the Sigma Pro still takes up reasonable space in a bag, jacket pocket, or desk drawer. The additional weight is negligible.
When the Sigma Pro is on the move
In mobile use, connected to a smartphone via Bluetooth or USB-C wired connection, the Sigma Pro passes from hand to hand, rests on various surfaces, and faces the hazards of transport. The case absorbs light impacts and prevents the glass from coming into direct contact with hard objects.
For home listening sessions, the case also offers an unexpected advantage: it improves grip. The slightly textured leather surface offsets the slippery nature of the glass and sandblasted aluminum.

Frequently Asked Questions
Is the case compatible with the original Sigma, or only with the Sigma Pro?
This case is designed for the Sigma Pro. The dimensions differ slightly between the two models and the port locations are not identical. Questyle offers a separate case for the original Sigma.
Can the Sigma Pro be charged without removing the case?
Yes. The cutouts leave both USB-C ports accessible. The port dedicated to charging remains unobstructed, as does the data port. Listening while charging works without any extra handling.
Does the case interfere with the Sigma Pro’s heat dissipation?
The Sigma Pro warms up moderately during prolonged use. The leather does not cover the glass faces where most of the heat dissipation occurs. Under normal use, there are no overheating issues to report.
Do the LED indicators remain visible?
The status LEDs are located on the top side of the Sigma Pro, an area not covered by the case. Volume level, gain mode, Bluetooth or USB connection: all this information remains visible.
Is the case available in colors other than black?
Questyle offers this case in black. Other colors may be available depending on markets or time periods.
Does the case protect against drops?
The case softens light impacts and protects against scratches and everyday wear. A significant drop onto a hard surface remains risky for the Sigma Pro’s glass panels, regardless of the case used.
