Questions

What is a tDCS Headphone and how does Sychedelic use it?

A tDCS headphone is a wearable that combines high-fidelity audio with transcranial Direct Current Stimulation. It uses low-intensity electrical currents to gently nudge brain activity toward a desired state. Sychedelic uses closed-loop modulation — reading your real-time neurophysiological data to deliver the exact amount of stimulation needed — and targets the prefrontal cortex to help dial in focus, flow, or calm on demand.

How do Sychedelic PPG Headphones improve stress tracking?

Sychedelic uses optical sensors near the ear and temple to capture high-fidelity HRV, Blood Volume Pulse, and vascular tone data. The skin near the ear is thinner and less susceptible to motion artefacts than wrist-based devices, allowing more accurate and faster detection of autonomic stress shifts.

Is Sychedelic just another Stress Wearable?

No. While many stress wearables only notify you after stress spikes, Sychedelic is built for proactive regulation. It detects early autonomic shifts and supports stress relief through biofeedback, sound modulation, and neuromodulation — acting before stress escalates into burnout.

How does Sychedelic support focus?

Sychedelic combines Active Noise Cancellation, spatial audio, auditory stimulation, and neuromodulation. This multi-layered approach reduces neural noise and sustains attention during high cognitive load, making it easier to enter and maintain deep focus states.

Can Sychedelic provide wearable stress relief?

Yes. By monitoring HRV and vascular patterns in real time, Sychedelic offers stress relief that supports nervous system balance before stress escalates into burnout. The closed-loop system adapts its intervention based on your current physiological state.

Why is the ear a better location for biometric sensors than the wrist?

The skin around the ear canal and temple is thin, rich in micro-vasculature, and directly influenced by the brain's regulatory centres. PPG signals captured here are far less susceptible to motion artefacts than wrist-based readings, and the proximity to the head means autonomic changes — like HRV shifts during stress — are reflected more quickly and accurately.

What does Sychedelic detect that a standard fitness tracker cannot?

Standard fitness trackers report steps, calories, and basic heart rate. Sychedelic tracks cognitive state in real time using PPG-derived HRV metrics — RMSSD, LF/HF ratio, and pNN50 — sampled at 100 Hz near the ear. It classifies your autonomic state across five zones and uses that classification to gate when tDCS stimulation begins, making it a proactive cognitive system rather than a passive data logger.

Is cognitive wearable technology safe for everyday use?

Sychedelic uses two non-invasive modalities: optical PPG sensing and tDCS at 2 mA, both of which have extensive safety records in research literature. Bikson et al. (2016) reviewed 33,200 tDCS sessions with no serious adverse events at standard parameters. As with any wearable, absolute contraindications (active epilepsy, implanted cardiac devices) apply.
