Thank you for the correction. I just assumed 2.5 lol

Those are for the terminations that plug into the headphones. You need a 3.5mm for the Sundara, and then select a 2.5mm TRRS as the single end termination for balanced.

I had my Sundara for 2 years without a single issue. The only reason I sold mine was because I wanted the Edition XS and knew my friend would enjoy the Sundara as much as I did. They're still going strong!

Return and give it another whirl!

That article lost me at "Knowing that all the characteristics of headphones are in frequency response graph..."

Their sound is so massive. I've seen them live 4 times, 2 of which were on their most recent tour, and I would love an opportunity to hear something even remotely close to the power of their live shows.

Fantastic. Enjoy, it only gets better! A few highlights that are some of my favorite moments on the album:

- The breakdowns in Pneuma, as well as the instrumental jam later in the song

- A heavy groove at 9:35 in Invincible

- Every aspect of Descending. It's my favorite song of all time, and a composition of epic proportions

My favorite album with anything is Fear Inoculum by TOOL. The thing is MASSIVE it terms of, well, everything. It's truly a masterpiece.

As far as headphones, I'm moderate. I rock the Hifiman Edition XS at my desk, driven by an ifi Zen CAN with a BTR5 that I use as a USB DAC. On the go, I rock the Etymōtic ER2XR and my BTR5 or just my Galaxy Buds Pro 2.

Edit: I hope one day I get experience Fear Inoculum in its entirety on a hi-fi sound system, in someone's listening room that costs almost as much as my house.

Impedence ≠ SPL

Loud enough ≠ enough power
