Those are 5mm drivers, 2 per side. Here's a quote from the Sensaphonics D2 intro press release a couple years back:

Sensaphonics D2 is a dual dynamic design using proprietary Dynamic Resonance Chambers. Here's a review from pro audio world: https://fohonline.com/articles/road-tests/sensaphonics-dual-dynamic-custom-iems/

Sensaphonics does still offer 2X-S, 2MAX (neutral) and 3MAX (bass). They've also added their first dynamic, the D2. Slightly bass-forward, dual driver, and only $600. Most recent offering is 3DME, with embedded binaural mics for Active Ambient pickup, and an app providing 7 bands of EQ, limiter...

Sensaphonics maintains its 2X-S, 2MAX, and 3MAX models, and has also added its first dynamic CIEM, the D2. It's a dual-driver design, full silicone shell, with a warm, bass-forward sound, and only $600. Here's a review link...

Ah, you are referencing Stumpy Joe, who was Spinal Tap drummer #2. He choked on (another person's!) vomit.

No! In fact, if Tap's Drummer #3 had used a water-based IEM like these Magic-Grow AudioFoams, it's likely his tragic end could have been averted...

I'm clearly not up to speed on the situation, as I've obviously horribly misread the photo. I understand that the office is in touch with you directly, so I'm bowing out now, wishing you well.

Hi thmmax. The photo you posted does not show the IEM properly inserted into the ear canal, nor the helix tucked in. Not even close. From the angle shown, it's hard to tell exactly what the issue might be. But yes, obviously something is wrong. Maybe other SCS users here can advise. Have you...

Thanks for the kind words. The D2 is reviewed in the October issue of FOH Magazine. http://fohonline.com/articles/road-tests/sensaphonics-dual-dynamic-custom-iems/

This is a pretty decent approximation of the sound of my tinnitus.

Hi Mython, we basically agree. Please note that my post was a response to BigKD, and was a cross-post to your evaluation. And yes, as a MOT, my comments require a certain amount of diplomacy. It only chafes a little.

Those are legit concerns, BigKD, and the difference between left and right impressions may be a red flag. Hard for me to comment further, as Sensaphonics does only deep-canal, full-shell IEMs, where the silicone earpieces actually reach as far in as the impression is made. That is typically not...

Weird that no foam oto-block was used in the untipped side. I assume it just fell off? I further assume that the goldish tip on the other side is a substitute for the the foam-with-string oto-block I'm used to seeing. To answer your question, these don't look great, but every manufacturer has...

Saw this old thread come up in a Google search, so it seemed like an opportune moment to post some science: Silicone Isolation Study - Michael & Associates
