Klipsch M40 Mode

MSRP $349.99
This product is no longer available at HeadRoom.

The Klipsch M40 Mode headphones are full-size cans sporting newly designed 'dual driver' transducers featuring discrete tweeter/woofer crossovers with a 40mm low + mid driver buttressing a 15mm tweeter. The plush sealed-back earcups are fully circumaural to cover the entire earlobe and remain extremely comfortable even during extra-long flights or endless commuting. New Klipsch state-of-the-art 'active' (battery powered) noise cancelling operates for up to 45hrs on a single charge and the M40 remains operable for audio even without batteries!

For listeners out and about, good isolation is key to avoid cranking up your headphones to ear-bleed decibels merely to overcome environmental ambient noises. The Klipsch M40 Mode headphones feature 'active' battery-powered noise-cancellation [NC] along with additional noise-suppressing sealed-back earcup construction that affords excellent privacy for airline and road travel, meaning you can listen at quieter volumes with less fatigue while preserving your long-term hearing. The Klipsch Mode also features an on-board iPhone / iPad telecommunications microphone cable for making calls with a 3-button skip/ track forward / volume controller located on the cord. The M40 Mode's fairly unique audio design features a dual-driver 15mm tweeter in tandem with a co-axial 40mm woofer array that pumps out a nice, big bottom-end for music. However, the overall tonal balance seems geared for maximum voice/speech recognition and doesn't realize a whole lot of brightness or upper treble extension. That might perhaps be considered a good thing for listeners sensitive to piercing highs seeking to avoid sibilance or treble screech.

The Klipsch M40 Mode noise-cancelling headphones come in a crisp black-on-copper look that shares cosmetics with the rest of Klipsch Reference [in-ear] line and neatly sets them apart from the the pack. The M40 Mode's oversize, extra-plush sealed earcup construction covers the entire earlobes on almost all wearers which contributes mightily to its excellent environmental noise attenuation properties. The powered noise-cancellation runs for up to 45hrs on one AAA battery. As a huge plus, the Klipsch can also be used without a battery as straight 'passive' stereo headphones so your music can continue unabated for the entire duration of your trip --something that not all NC headphones can claim. High-grade genuine leather earpad cushions and headband frames surround your listening exprience with comfort, even during those long hours aboard transcontinental flights. Detachable 'audiophile-grade' OFC headphone cables (one includes the Apple controller on-cord) allows for long product use life and easy cord replacement if ever needed. The provided leather travel case is a slim-profile design that contains all essential M40 Mode accessories like airline adapters or extra cords. The 2-year manufacturer's warranty remains free only with a Klipsch 'authorized dealer' purchase receipt -- like the one you'll get here at HeadRoom!

Sadly, disappointed
Posted by MrSuperdudly1 from Florence, KY on 2012-12-08

Recommend Product: No
Pros: Good build. Solid feel.
Cons: Disappointing sound quality.

I'm a huge fan of Klipsch and purchased these with high expectations. With the dual drivers, I expected these to have exceptional highs but I was disappointed to find how lacking they were. They were very bass heavy and sounded rather dull. I tried using them with amps and special eq's and couldn't get them to sound as good as I had envisioned.

I still love Klipsch, but these were just not what I was expecting.

Sound great - if you have a small head...

Recommend Product: No
Pros: Great tonal qualities throughout
Cons: Put your head in a vise and squeeze...

Okay, so they are high end Klipsch phones - you expect them to sound great and they do not disappoint. That said, I don't know anyone who can wear them for more than very short duration's of time. I bought them thinking they might break in with time but the longer I owned them, the more I hated wearing them. My hat size is a very average 7.25 so it's not like I've got an over-sized melon or anything; I just don't like the feel of my head in a vise...
