MrSpeakers is a line of headphones that have been getting rave reviews. They make high value planar phones that are exactly what we like to sell at underwood Hifi. These phones compete with far more expensive products and offer superb value.Their first phone, the Ether, was received exceptional press and the new Aeon Flow, open and closed back phones at only $799.00 are the best value phones we have heard.

When they discontinued their original Alpha and Mad Dog headphones, MrSpeakers promised to deliver a variety of headphones to meet many needs and budgets.  Their first phones, the ETHER and ETHER Flow phones collectively won more than 20 awards for performance and design.

Their latest in-house designed headphone, AEON packs all the technology of ETHER Flow headphones into a compact, comfortable and cost-effective design, delivering the best of ETHER Flow sound quality at a dramatically more affordable price point.

And they’re still designed and built in San Diego, California.

Ether Headphones

When they started design of their first in-house headphone MrSpeakers set out to deliver industry-leading sound, genuine comfort and timeless style.  The result is their award-winning ETHER headphone lineup.


ETHER® headphones are not about having the best bass, mids, or highs, they’re about delivering a convincing experience. The goal is to NOT emphasize any part of the spectrum, but rather to have it blend together to form an organic whole.


ETHER® headphones are renowned for their fit. With a nearly ideal weight distribution and plus Italian lamb-leather ear pads, they can be worn for hours without fatigue.  ETHER headphones won’t move around on your head with normal usage, but neither will they leave your jaw and ears aching from clamping force, truly they’re a headphone you can enjoy for hours at a time.


ETHER®is entirely metal for durability and sound quality yet is extremely light and comfortable.   The team worked overtime to cut weight without sacrificing performance.  Now you truly get it both; bullet proof construction and comfort.

In an innovative industry-first they created a NiTinol “memory metal” headband that is super-light and ultra-cool.  It delivers just the right level of clamp and is remarkably tough and reliable.
