Ultimate Ears UE350Vi

MSRP $59.99
This product is no longer available for purchase.

Tuned with an audible extra bass kick in the low end, the Ultimate Ears UE350Vi include a built-in microphone and on-cord controls that give you the flexibility to take a call and get back to the music without missing a beat. If you're exhausted by the thin, lackluster bass response of most in-ear headsets, the UE350Vi will keep the party beating 'til the break of dawn direct from your Pandora, Slacker or iTunes music collection with plenty of satisfying authority and heft in the lows. Fortunately, the balance is spot-on so you won't miss clear mids and highs amongst all the engaging thumpitude.

We get lots of calls at HeadRoom from Apple iPhone users wanting to add some bass to the weak-willed low-end of their smartphone earbuds. As always, HeadRoom has the answer with the Ultimate Ears UE 350vi in-ear monitors / earbuds. With a high-quality mic plus 3-button control located on cord, the UE350vi employs the easy-to-wear 'shallow-fit' design typical of earbuds with the added niceties of personalized eartip options and excellent noise isolation properties offered by deep-ear monitors [IEMs]. The UE 350vi neatly splits those ergonomic differences with a comfortable earpiece that almost anyone can wear, even newbies to in-ear headphones. Of course, big bassheads needing to hear big kick drum and well-reproduced bass guitar have come to the right place. The Ultimate Ears UE 350vi tone has tons of bottom-end authority certain to please bassheads everywhere. Luckily, its also without dreary murk or darkness infecting the rest of the sound, so the overall presentation avoids dreaded "one-note" boomy bass response -- a rather difficult feat to achieve, specially at this good price -- and the music retains impressive texture even in the lowest octaves. The mids /highs also remain present with good detail and upper-note extension, a great thing for extra-clear voice or speech intelligibility for the phone chats. We're stoked the UE 350vi 'Extra-Bass' design is not marketing shorthand for "bass only" sound. Really a great HeadRoom-recommended deal on high-quality iPhone in-ears for bass thumpitude seekers.

The Ultimate Ears UE350vi earphone comes from a long line of high-quality in-ear designs dating back to the pioneering UE 'Super.Fi' models back in the early 2000s. Now completely updated by Logitech with all the latest technological in-ear monitor advancements like weightless rapid-response neodymium driver arrays and extra-tough Kevlar cord reinforcement, the build construction of the UE 350vi appears well-built to withstand non-stop portable jamming when out and about. The slightly-rounded, small flat-back earpiece on the UE350vi makes it useable for under-helmet wear for bikers or cyclists while also rendering it ideal for sleeping or laying down without protuding earpieces ruining the shut-eye. The UE350vi package includes several pairs of proprietary eartip sets, amongst the most effective selection of 'universal fit' ear sleeves offered by any manufacturer. The 2-year free 'repair or replace' service warranty remains in place only with your HeadRoom authorized Logitech/UE dealer purchase receipt.

Outstanding price-performance ratio
Posted by Clearmind from American in Taiwan on 2013-02-05

Recommend Product: Yes
Pros: Perfectly balanced sound, deep bass
Cons: Very few (see review)

Even though the website review emphasizes the bass kick of these 350s, the overall sound is beautifully balanced and the highs are also well-extended. Even though they have slightly less detail or definition than more expensive IEMs like the Klipsch X10i, their bass-midrange-treble balance is managed so beautifully that they work surprisingly well over a broad range of genres. If you use a really clean source like the Fostex HP-P1, they will sound surprisingly detailed and will even work for some (but maybe not all) classical--their slight lack of tonal refinement or clarity limits them slightly in this regard. String quartets seem to work pretty well, orchestral strings sometimes less well. But for most stuff, including pop, rock, electronic, and soundtracks, they're just great. Even though I have more expensive IEMs, I still use these on a regular basis for a lot of music.
