Wearable Sensing DSI-24 Wireless EEG Headset For Sale (used)


I am selling one used Wearable Sensing DSI-24 Dry EEG Headset, originally purchased in October 2015. The cap is in good condition, with one electrode (P3) just slightly bent out of position but still functioning. Can be easily repaired back into place. EEG Acquisition through native DSI Streamer software (included), as well as modules in NeuroGuide (can be included if asked).

Please email jessica@jtolentino.com if you are interested!

we would be interested in the cap, could you tell us what would be the price?

Hi Kerstin,

In perfect condition, the headset is worth about $12,000USD. However, there are a couple of mostly cosmetic defects worth noting.

  1. The bracket holding the T6 electrode is slightly bent/skewed. But it can be easily adjusted into place once the subject is wearing the headset
  2. One of the magnets that holds the ear clip is missing. This does not affect the function of the headset during use

I have photos of all of this and would be happy to email them to you if you provide an address. All said and done, we will drop the ask to $11,500. The headset was serviced by the manufacturer and has only be lightly used since and also includes an extra set of electrode head replacements ($200 value).




Correction: the bent electrode is P3



Hi Kerstin, I just wanted to follow up. Are you still interested in the cap?
