Review: Logitech Ultimate Ears UE 9000 – IEM Company’s First Step into Headphones

Logitech | Over-Ear Headphones | $ 399.99

For nearly the past decade and a half, Ultimate Ears has been an IEM-only company. They have seen their roots from custom-fit monitors flourish into universal styles that everyone can enjoy. It wasn’t until after Logitech took over that they took their first steps into full-sized headphones. The UE 9000 represents Logitech Ultimate Ear’s flagship model.

Logitech uses a beautiful, black housing that is glossy and flashy. Silver accents connect them to the headband while a bold blue strip runs around each housing. The metal hinges swivel while a blue cable dominantly leaves each headphone. Aesthetically speaking, the UE 9000s are very pleasing and stand out in the crowd.


Design: ★★★★


Logitech offers 3 listening modes with the UE 9000: wired (passive), wireless, and noise canceling. Both the wireless and noise canceling modes sound identical while the wired mode offers a closer-to-neutral sound. Regardless of mode, the UE 9000 have a V-shape to them. Strong bass couples with a clear, warm midrange that comes together with an energetic high end.


The low end offers good depth into the sub-bass regions allowing the headphones to create a nice fluid texturing while the upper bass keeps a strong solid feel to them. The lower-bass impact is resilient and firm. It is the most prominent part of the entire spectrum. It, however, can take a bit away from the mid-bass in general. The punches aren’t as tight as I’d like them, rather a little smooth.

Putting the headphones into the wireless mode, we find that the low-bass impact increases drastically. The headphones nearly become boomy while sub-bass presence increases.

 Bass: ★★★★½


The midrange is very warm and inviting. Detailing is strong throughout the entire spectrum. Clarity, however, lacks in the lower-mids while being ample in the upper-midrange. Vocal’s show strong dynamics being able to go into the deeper, lusher areas and come back out when the sweetness and energy is needed in a singer’s voice. The midrange as a whole just has a very warm sound to it, but doesn’t take away from quality.

When the UE 9000 go into Bluetooth mode, the midrange drops quite a bit. Detailing can be lost in the lower mids. Vocal dynamics are affected in the lower-end as well. Clarity and higher vocals remain intact.

Mids: ★★★★½


Going up into the treble regions, we find that the UE 9000 do their best to add energy. They actually do a fine job with it too. The upper-highs, although they can extend a tad bit higher, are clear with a strong splash. Separation is beautifully crafted in the highs. Lower-treble has decent presence, but decay slightly fast for what I need in the treble.

Going into noice-canceling mode, the treble doesn’t change all that much. The lower-treble does lose presence though, decay also cripples a bit in this area as well. Energy increases though in the upper-highs.
Treble: ★★★★½

Audio: ★★★★½


Logitech did a lot to ensure that the UE 9000 would last quite a while. For starters, the nice molded carrying case is included to keep the headphones protected when not in use. Although I feel they could survive without it, it’s always better to be safe than sorry. In addition to protecting the headphones, it will also fit all the accessories that come with the UE 9000.


Composed of thicker plastic, the housings on the UE 9000 are resilient and strong. Connecting the housings to the headband are thick pieces of metal. The hinges are connected using metal and move in a fluid fashion while the swiveling housings snap in and out of place very smoothly. All of this just gives the UE 9000 that prestigious build.


The headband is flexible and made of plastic it seems. It gives little to no resistance to changes in shape and really doesn’t feel the strongest. I’m sure it’ll last a little while, though, but it doesn’t seem as tough as the rest of the headphones.


Although not required for use, the cable is very durable being composed of thick, blue rubber. It is decently flexible and doesn’t tangle too easily. Both sides have strain reliefs before their 3.5 mm jacks and the jack that plugs into the DAC is angled to ensure it’ll last a little longer.

Build: ★★★★½


These headphones use very thick pads around the housings to make sure they are comfortable when they are first placed on the ears. Very little clamping force is applied which helps quite a bit more. Their weight, however, is their main downside. After about an hour, maybe an hour and a half, the weight becomes a bit much.


Comfort: ★★★★


The UE 9000 come in around 400 dollars. The fact that they are Bluetooth and noise canceling helps a bit. The noise canceling properties of the headphones are pretty decent. Being able to go wireless is nice as well. A remote and mic’d cable allows for a passive mode and use with iDevices (although Bluetooth will work as well). The headphones also have a passive button that will mute the music and let external sounds in (and amplify them). I just wish that this feature would work wired and in NC mode as it only functions properly while being used wirelessly.


Otherwise, for 400 dollars, the design and build are top notch. Like the UE 900 though, there will be headphones in a lower price range that will match the 9000’s technicality. The flexibility of the headphones adds a bit of value however.

Value: ★★★★½

Final Thoughts

Taking their first steps into the full-sized headphone business, I have to say that UE did not do a bad job. The UE 9000 will definitely appeal to the more popular audience with the stronger low-bass and more v-shaped signature. They don’t sacrifice quality and go wireless as well.

I’d like to thank Logitech for the product sample.
