Your Favorite Entry-Level Headphone, Revived

In 2010, HiFiMAN released the HE-300, HE-500, and HE-6: a series of headphones that redefined price-to-performance expectations in their respective categories and solidified the still-young company’s status as one of the most respected names in the audiophile community. Inspired by the HE-300, which was eventually discontinued despite being a clear favorite for many, we teamed up with HiFiMAN to make the HE-350. This new model has everything you loved about the original, plus a few awesome updates made in response to feedback and requests from the community.

Note: This item is in stock and will ship in 2–3 business days. Your payment method will be charged 2 hours after joining. Cancellations are accepted until that time. The drop will launch and end each day to collect purchases.

Sound & Construction Details

The HE-350 uses entirely new dynamic drivers, different from those in the HE-300, resulting in a more neutral sound signature with less distortion and more detail. We've also improved the cable connectors and plug, and updated the frame to HiFiMAN’s latest (and much lighter) structure. We made the headband more comfortable for those long listening sessions, and changed the colorway from black and silver to a more understated black and gray. Best of all, we’re able to offer the HE-350 for an even more accessible price.

Easy Bass-Boost Mod

If you’d like to add more bass or warmth to the sound signature, try this simple mod. Please exercise caution when removing the ring from the housing, as the tabs around the ring are fragile and may break without proper care. For a step-by-step look at the process, check out this video.

It truly is sad that marketing has pushed for "low impedance = easy to drive." The number you should initially look at is efficiency and/or sensitivity. Efficiency helps inform you how much energy it takes to produce a certain sound pressure level (SPL) aka loudness given in dB/mW units. Sensitivity informs you how much voltage you need for a certain loudness given in dB/V. Both terms help define how easy or hard a pair of headphones is to drive. Another important thing to look at is the amount of current needed for a given loudness. A website like http://www.digizoid.com/headphones-power.html can help with figuring that out. Manufactures often only list one or the other (dB/mW or dB/V). Massdrop lists sensitivity but often enough it's actually listing efficiency (have to check manufactures websites). And... even manufactures misuse these terms. You have to look at the units (dB/mW or dB/V) to truely know which is being used. Hence, the confusion everyone seems to have. It's not exactly straight forward to determine if a headphone is easy to drive. In this case, the HE350 has an efficiency rating of 93 dB/mW (btw higher the number the easier it is to drive). If you compare this to enough headphones you'll learn it isn't the worst, but it's still pretty bad for a consumer headphone around this price . If you enter in this information into a website like http://www.digizoid.com/headphones-power.html you'll see that to get 110dB SPL, you need ~1Vrms and 50mA which is basically at the limit or too much for many devices to provide. side note : 1Vrms = about 3V peak to peak - nearing smart phone battery limit. And the op amps (simple amplifiers) probably used in your portable device have current limits between 35mA and 70mA from what I've seen (not confident what a good range should be). (for these headphones) If you want it another 5dB SPL louder, voltage and current requirements nearly double. If you want another 5dB, nearly doubles again. It wouldn't surprise me if many devices can only get these headphones to 105 dB SPL, which is probably why you find them to be kind of quiet.
