Sharp looks, smooth sound

If you're serious about music, then you have something in common with Yamaha. The renowned maker of musical instruments and audio equipment is taking their expertise directly to your ears with its slick-looking line of headphones. Their PRO 400 headphones look sharp while bringing clarity to your music with crisp highs and deep bass response that is full but not boomy. Yamaha's proprietary neodymium-magnet drivers are optimized for efficiency, so your portable device will easily push the PRO 400s to peak performance.


Yamaha PRO 400 in-line remote and microphone

The PRO 400's in-line remote lets you control music playback and take calls on an iPhone.

Go with or without a remote

When you're listening on the go, it's always easier to control your music with an in-line remote. The PRO 400 features a three-button remote for volume and track control without removing your iPod® or iPhone® from your pocket or purse. And the built-in microphone lets you make phone calls on your iPhone as well, with the remote providing convenient answer and hang-up functions. If your mobile device isn't compatible with Yamaha's remote, you can swap out the detachable cord with the included standard cable or add an aftermarket cord designed for your particular device.

A smart choice for any listening environment

Cleverly designed to highlight Yamaha's iconic logo on the earcups, remote and miniplug connector, the PRO 400 headphones are as stylish as they are comfortable. The nicely cushioned earcups fit snugly around your ears, while the sturdy headband provides just the right amount of clamping force to keep them secure without feeling too tight. The around-the-ear design also provides excellent noise isolation, so you can enjoy your music without external sounds leaking in. It also means you can listen anywhere without sound leaking out and disturbing others, whether you're in the office, the library or on the go. Fold them up and stash them in the carrying case for instant portability.

Magnificent value for the price. The drivers are superb with a wide sound stage and accurately defined instrument sound. There is a Wow factor to be heard. Highs are crystalline and both mid and bass ranges do what they should. Solidly supporting the music. Everyone's head will respond to the comfort of these headphones . I was surprised at how quickly I adjusted to the newness. They molded to my cheek and bone structure much faster than expected. The sound is top of the line. The Crutchfield review that referenced not wanting to return them to the evaluating table and keeping them for a week is very understandable. These are the first "out-of-the-box" headphones that have hit the mark for me. I'm sure others would, if I spent twice of three times the money. You aren't going to find a better set of headphones for the money.

Pros: Sound is exemplary. comfort is good value is exceptional

Cons: None

I like that these while not featherweight will rest on your ears comfortably with the framers the back of your head working well for regular in-flight use.

Pros: Construction cost sound

Cons: Full size so they are bulky

Product Research


Overview: The Yamaha PRO 400 headphones have an over-the-ear design to isolate noise. The folding design lets you collapse them and store them in the included semi-hard zippered case. They come with two tangle-resistant flat cables: a 4' cable with an in-line remote and microphone so you can control your music and phone calls with ease, and a 10' cable to use at home or in the studio.

Audio Quality: The PRO 400 headphones deliver superb audio performance. The newly-developed 50mm Yamaha-proprietary drivers have powerful neodymium magnets that make them easy to drive with today's portable electronic devices. You'll get accurate musical reproduction for most any kind of music. The over-ear design shuts out external sound so you're only hearing the music, not the outside world.

Comfort: The soft padded ear cushions and adjustable headband give you hours of listening pleasure without fatigue. The headband is shaped to apply just the right amount of pressure--not too tight, but snug enough to isolate much of the exterior noise.

Cables: The PRO 400s come with two cables: one for portable use and the other for home/studio use. The tangle-resistant flat cables separate the internal cores to minimize interference. They are coated with a durable rubber-like material to reduce contact noise. The 4' cable terminates into a right-angled 3.5mm plug, while the 10' cable has a straight 3.5mm plug. A gold-plated 1/4" adapter is included for listening to your home audio equipment.

In-line Remote/Mic: The PRO 400's 4' cable has an in-line remote control and microphone that is optimized for Apple iPod, iPhone, and iPad. The 3-button remote has "+" and "-" buttons for raising and lowering the volume, while the center button controls your music (play, pause, skip to next song, skip to the previous song) and your phone calls (answer call, end call). The remote/mic is compatible with:

  • iPod:
    • shuffle: 3rd generation and later
    • nano: 4th generation and later
    • classic: 120 GB, 160 GB
    • touch: 2nd generation and later
  • iPhone: 3GS, 4, 4S, 5
  • iPad: iPad and iPad2


  • Frequency Response: 20Hz-20kHz
  • Sensitivity (dB/1mW): 106dB
  • Nominal Impedance: 23 ohms

Product reviews from the Crutchfield Labs

Full sized, full of sound

Written by Chris, Advisor, on 11/7/2013 2:40:00 PM

I grabbed these beauties from the Crutchfield Lab the other day and brought them to my desk to try for a couple of hours. Almost a week later, I decided I should probably put them back for others to hear.

My first impressions were that they were pretty heavy on my head and seemed to squeeze a little tighter than I thought I'd like. After using them for a while though, I determined that those feelings were due to being too accustomed to my Monster in-ears. The size, weight, and pressure was less apparent as time went on.

These headphones sound great, it's that simple. Yamaha knows audio and these 'phones are no different than the rest of their gear. I plugged them right into my PC with no additional headphone amp and I listen to Pandora predominately. Those are certainly less than optimal conditions, and the 'phones still manage to bring my music to life.

Do I really have to give them back?
