In-ear monitor headphones
Sony IER-M7 - Quad-driver system (four balanced armatures) in each earpiece for finely detailed sound across a wide frequency response
Sony IER-M7 - An advanced crossover system in each earpiece helps deliver musical detail with low distortion
Our take on the Sony IER-M7 by Crutchfield's Jeff Miller
Designed for professionals and serious listeners
Few companies are as involved with the entire music "chain" as Sony. They help create music, and make gear used to record, produce, and enjoy it. Having a hand in every step of the process really helped shape the sound signature of the Sony IER-M7 in-ear monitor (IEM) headphones. These IEMs are designed for use in live performances, but they have a clear, vividly detailed sound that would appeal to headphone enthusiasts as well.
It's all thanks to their quad-driver design. Sony packed each earpiece with four balanced-armature drivers and a sophisticated crossover system. I've only had the chance to spend a few minutes with them, but I immediately picked up on their outsized soundstage and accurate imaging. A live orchestral piece sounded properly spread out, and each instrument had a sense of place.
Professional-level noise isolation
Things get loud on-stage, and it's crucial to be able to focus on your specific instrument or vocal. Sony built these IEMs so professional musicians can do just that. I can tell you firsthand, it works well in an office setting, too. The IER-M7s knocked out outside distractions so I could focus on my tunes.
A large assortment of ear tips, for better fit and sound
We often talk about fit in terms of comfort. But getting a good in-ear seal has sonic advantages, too. Fortunately, Sony includes 13 different pairs of ear tips — maybe the most I've ever seen.
There are seven sizes of hybrid silicone tips, and six sizes of what Sony calls "triple comfort' tips. I personally preferred the latter. They were made of a soft, spongy material that helped create a comfortable, secure seal.
Detachable, wrap-around cable options
Sony includes two wrap-around-the-ear cables with the IER-M7. I had to overcome a small learning curve to get the right fit — you wrap the cord around your ear like you've probably seen musicians and performers do with their in-ear monitors. Once properly secured, they felt like they wouldn't slide around at all, no matter how I moved my head.
One cable includes an unbalanced 3.5mm mini plug. These in-ears are efficient enough that you can connect to your phone, but you'll get even better sonic results with a portable high-resolution music player. In fact, the second cable includes a 4.4mm balanced headphone plug so you make a balanced connection to Sony's NW-ZX300 Walkman®. Sony developed this new industry standard connection to help cut down on signal noise and distortion.
