eSynic 3.5mm to Optical Converter is an audio converter that turns analogue 3.5mm output into optical digital, improving clarity for TVs, soundbars and projectors. Musicians and home cinema owners gain cleaner audio and simpler connections without hunting for extra leads. Is this the most straightforward way to link older headphone jacks with modern optical inputs?
⚡ At a Glance
- • Audio Output: Uncompressed 2-channel PCM digital output, supports 48 kHz sampling
- • Best for: Connecting laptops, projectors and soundbars that lack analogue inputs
- • Not ideal for: Systems requiring digital-to-analogue conversion or multi-channel surround formats
Converts analogue 3.5mm signals into optical TOSLINK digital output. Includes an integrated 3.5mm cable and a 1-metre optical lead for immediate use.
Cleaner Digital Sound – Thanks to analogue-to-digital conversion supporting 48 kHz PCM
On-board analogue-to-digital conversion accepts a 3.5mm stereo input and outputs a two-channel PCM signal at a 48 kHz sampling rate over an optical TOSLINK connection. Design focuses on preserving an uncompressed stereo signal rather than downmixing or compressing audio.
Produces clearer, interference-free digital audio for soundbars and digital inputs, useful where analogue connections introduce noise or hum.
Hassle-free Setup – With an integrated 3.5mm cable and supplied 1-metre optical lead
An integrated 3.5mm lead removes the need to match separate analogue cables, while the included 1-metre optical lead connects directly to TOSLINK ports. Plug-and-play arrangement means no additional adapters or cable hunting.
Allows fast connection from laptops, projectors or phones to optical-only equipment, saving time when setting up home cinema or presentation systems.
Stable Signal Transmission – Thanks to aluminium alloy casing and EMI compatibility
Aluminium alloy casing aids heat dissipation and improves electromagnetic compatibility, helping to reduce interference during analogue-to-digital conversion. The physical build is aimed at maintaining consistent signal integrity.
Delivers steady audio with fewer dropouts and less background noise, suitable for compact media setups where reliability matters.

❓ Frequently Asked Questions
Q: Can this convert optical signals back to analogue 3.5mm?
A: No, the device is an analogue-to-digital converter only and cannot be used as an optical to 3.5mm converter or to convert optical to RCA.
Q: What audio formats does it support?
A: Supports uncompressed two-channel PCM digital output at a 48 kHz sampling rate, suitable for stereo playback on compatible receivers and soundbars.
Q: Is any cable required separately for setup?
A: No additional cables are required, an integrated 3.5mm cable and a 1-metre optical lead are supplied for immediate plug-and-play use.
🏆 Our Verdict
A compact analogue-to-digital converter suited to anyone who needs to link 3.5mm sources with optical-only equipment. The combination of built-in leads, 48 kHz PCM output and aluminium construction makes for reliable, cleaner digital audio. While individual budgets differ, the straightforward compatibility and solid build give useful long-term value for home cinema and presentation setups.
