Cypher.V Replacement Aux Cable for Bose QC25 QC35

Replacement audio cable for Bose QuietComfort headphones with inline microphone and volume control, designed to restore wired listening and phone calling functionality.

If your original Bose cable is lost, worn or damaged, this Cypher.V replacement Aux extension cord provides a dependable way to reconnect your QC25, QC35, SoundLink or SoundTrue on-ear headphones to phones, tablets and laptops. Built with gold-plated connectors and a durable jacket, the cable preserves clear sound transfer and adds an inline remote and mic so you can answer calls and adjust volume without reaching for your device.

Will this cable fit my Bose QuietComfort headphones?

Yes — the connector geometry and wiring on this Cypher.V cable are made to match the Bose QC25 and QC35 (and many related Bose wired models). It plugs into the headphone jack and presents standard 3.5mm male plugs for source devices.

• Compatible with Bose QC25, QC35, QuietComfort 25/35, SoundLink and SoundTrue on-ear models.
• Two male 3.5mm plugs included: one straight and one right-angle (L-shaped) for flexible routing.
• Standard wiring supports stereo audio plus inline microphone and remote functions.

How do the microphone and remote buttons work with my phone?

The inline module contains a microphone and simple controls for calls and playback that are wired for iOS and many Android phones. You can answer/end calls, control basic playback, and adjust volume directly from the cable without touching the source device.

• Built-in microphone for voice calls and voice assistant use.
• Buttons support volume control and music play/pause on compatible iOS and Samsung devices.
• Plug-and-play operation—no app or pairing required for wired control.

Does this cable affect audio quality or durability?

Noisy or thin-sounding cables are often the result of poor connectors; this replacement uses gold-plated plugs and a high tensile-strength outer jacket to preserve signal quality and resist everyday wear. The construction is intended to provide reliable, low-noise sound transfer so your headphones continue to deliver the audio profile you expect.

• Gold-plated 3.5mm connectors reduce corrosion and improve contact conductivity for clearer audio.
• Reinforced cable jacket increases tensile strength and reduces tangling or breakage.
• Soldered connections and strain reliefs at each end for longer service life.

How easy is it to install and use this replacement cable?

Installation is straightforward: unplug the old cord from your Bose headphones and plug in the Cypher.V cable — no tools or configuration needed. The cable is fully wired for both audio and inline controls, so once connected you'll immediately regain wired audio and calling functions.

• Simple plug-and-play design — immediate use after connection.
• Includes one straight and one L-shaped 3.5mm male end for practical routing and portability.
• Compact inline remote sits along the cable for convenient access to mic and volume buttons.

Who is this for: This Cypher.V replacement aux cable is ideal for anyone who owns compatible Bose wired headphones and needs a robust, feature-ready cable replacement. Choose it if you want to restore wired listening and call-handling without sacrificing sound quality, or if you prefer a durable spare cable with inline microphone and volume control for daily commute, travel, or work-from-home setups.
