Subject: Re: [AUDITORY] Dry EEG recommendations From: Abhinav Uppal <abhinav.uppal@xxxxxxxx> Date: Sat, 28 Feb 2026 12:06:20 -0500--0000000000003cac79064be56026 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi Katie, Are the sounds ambient or delivered over earphones? I think there are more options if external sound is to be occluded, but ambient sound should be possible too for some devices. If full scalp coverage is needed I have used CGX's Quick-32r <https://www.cgxsystems.com/quick-32r> with subjects seated in a lab or office setting and listening to music over earphones. It could feel heavy after extended listening (30 mins to ~1 hour) but TRFs are recoverable. This is the device I have used the most for dry EEG and feels reliable. I haven't used Wearable Sensing but their DSI-24 <https://wearablesensing.com/dsi-24/> looks interesting too. If a more discrete device is needed for public wearing then around-ear or in-ear options could also be considered. These have been used in public settings for ASSR and ERPs (see work by Preb= en Kidmose <https://ece.au.dk/en/forskning/forskningscentre/center-for-ear-eeg/project= s/real-life-ear-eeg> and Martin Bleichner <https://uol.de/en/psychology/neurophysiology/team/dr-martin-bleichner>). Depending on how many subjects you are targeting the in-ear devices could either be custom-fitted or generic. I'm not sure if a commercial option is currently available for custom-fitted devices, I think various ear-EEG labs have just been making them in house. There are some open (cEEGrid <https://shop.openbci.com/products/ceegrid>'s gel version) and commercial options (NextSense <https://nextsense.io/>, IDU= N <https://iduntechnologies.com/>, Emotiv <https://www.emotiv.com/mn8>) but I haven't compared them -- other people on this list might be able to chime in!
