Edit: Expired now, it looks like hifiman invalidated the coupon code around two hours after I posted.

The Sundara are widely considered in the audiophile community to be some of the best value headphones available in their normal price class (generally considered a meaningful step up over other venerable headphones in their price range such as the hd6xx), and at $149 they are an excellent value. The sundara on a good sale are usually ~$250 new and $169 refurbished. If you have any difficulty replicating the price of $149 in conjunction with the iems, remember that the sundara must be added to the cart before either of the iems, and you can only add one of the iems, not both.

Sundara rtings review: https://www.rtings.com/headphones...ndara-2020

A few basics to get out of the way first, since I know people wander onto these headphone deals not realizing these are audiophile cans for critical listening: these headphones are wired only (no bluetooth or wireless connections of any kind), have no form of active noise cancelling, have extremely poor sound isolation (you can hear whats going on around you, and everyone around you can hear what you're listening to), and are heavy and bulky. They are designed to be used at home with a dedicated audio setup.

The sundara uses a hammock style headband, have the standard size hifiman round earcups, and are more compact than hifiman's higher end oval earcup headphones; the sundara weighs 342g.
The sundara are moderately power hungry due to having an impedance of 32 ohms with a sensitivity of 92 dB. While you might be able to just barely get away with not using an amp if you have a high quality integrated audio solution on your motherboard and aren't planning on using eq (equalization) at all, I highly recommend using these headphones with a proper amp. As planar magnetic headphones with low distortion they take rather well to eq, so eq is highly recommended (particularly to boost the bass near harman levels, since the bass is fairly lacking at stock). If you'd be eqing these headphones to any meaningful degree, an amp is basically required.
These headphones are not designed for portable use, and most phones and cheap usb-c to 3.5mm dongles probably will do a very poor job driving them.

The largest issue with these headphones is hifiman's quality control, unfortunately hifiman is infamous for poor quality control and poor product longevity. Poor driver matching, driver failure after months (or less) of use, crackling or rattling sounds when moving your head, and more are all relatively common complaints with hifiman headphones including the sundara. This is not by any means guaranteed, the majority of purchasers receive headphones without glaring issues or premature failures, but hifimans quality control and product longevity still stands out as being distinctly worse than that of other major brands.

The refurbished sundara come with a 1 year standard warranty, from what I've heard hifiman's customer service tends to be decent (at least in the US), but obviously ymmv.
Hifiman's warranty policy can be found here: https://store.hifiman.com/index.p...nty-policy

In my personal experience, the refurbished headphone I ordered previously from hifiman came in essentially pristine condition and have not had any issues whatsoever after months of use. That being said, this is only a single anecdotal experience, so ymmv.

Overall, if these headphones would fit your use cases and you're willing to purchase refurbished, the sundara alone at $149 are an exceptionally good deal, and the free iems are nice little bonus.
