| 8 mm Driver |
🎧 We are reviewing the Senfer UE, an earphone with an 8 mm dynamic driver, detachable cables and custom design. Senfer is a brand with many interesting earphones, for example the marvelous Senfer 4in1, the Senfer DT2 Plus and the Senfer 6in1.
The Senfer UE vs Senfer 4in1 vs Senfer DT2 Plus have very clear differences, the first and most easy one to notice is that the Senfer UE is the only one of all 3 that has a custom style design with the cables intended to be used above and around the ear, which is something that is also found in other earphones that we have reviewed in the past such as the KZ ZST, KZ ZS3, Sound Intone E6, QKZ W1 Pro, KZ ZS2, Seahf EG009 or the KZ ED12. Another clear difference of the Senfer UE vs Senfer 4in1 vs Senfer DT2 Plus is the fact that the Senfer UE is a single dynamic driver earphone while the Senfer 4in1 and the Senfer DT2 Plus are hybrid earphones (1 balanced armature + 1 dynamic driver for the Senfer 4in1 and 2 balanced armatures + 1 dynamic driver for the Senfer DT2 Plus) The Senfer UE single dynamic driver has a beryllium membrane (if that is of any importance to you)
The Senfer UE cable follows the line of the Senfer DT2 Plus and the Senfer 4in1 utilizing the same MMCX detachable cable. MMCX cables are one of the very frequently found type of detachable cables used on other brands and models such as the amazing Pioneer SE-CX8, Pioneer SE-CX9 or the Seahf EG009. The cables provided are very sturdy and durable, we got our unit with a black cable but this is a rare thing, usually they are bundled with either a blue cable or a transparent/goldish one but all of these cables are equally built.
Housings are pretty original and we do not mean this because of the custom shape but for the colors and combinations used.
You can buy the Senfer UE with: blue outer plate with black main housing, all black, red outer plate with black main housing (unit that we are reviewing), all blue, all red, red outer plate with blue main housing, black outer plate with blue main housing. Moreover, many sellers allow you to buy one earpiece of one color and the other one of other of your choice.
All the housings options have a semi transparent plate piece that allows you to partially see the inner guts of the earphone. It also exists an hybrid version of the Senfer UE that very confusedly is named Senfer UEs, besides the technical specifications difference there is also a big gap of price between both models.

Accessories & Packaging
The Senfer UE are provided with a detachable MMCX cable (in case that you already own one or several MMCX cable some sellers allow you to spare some money offering also an option to buy it without the bundled cable) as well as the Seahf EG009, the Senfer UE do not have a packaging but they are usually sold with a good quantity of accessories: 3 black and blue eartips, 3 black and red eartips, a carrying case, cable clip. It is worth noting that usually earphones that are sold without an official packaging are subject to a variation of accessories provided that may depend on each seller.
Bass & Sub Bass
The 8 mm dynamic driver of the Senfer UE is capable of offering an outstanding quantity of punch and super deep sub-bass right out of the box with no use of an EQ to enhance their bass. Bass is something that certainly will never lack with these earphones even for very bass demanding songs or music genres.
With an EQ there was an insane increase of depth and punch.
During our standardized extreme bass tests using a custom basshead EQ and amplifying with a Fiio E12 set to high gain and bass boost turned on, the Senfer UE were able to handle up to 40% of the Fiio’s maximum power with an exponential enhancement of their mid-bass punch and depth of their sub-bass. Although their handling power capacity was not as high as other of the Top Basshead earphones in our Top Charts like the Sony MDR-EX800ST, Sony MDR-XB50AP, Plextone X41M, Plextone X50M, Xiaomi Mi Pro Hybrid or the Puma Bulldogs; the Senfer UE were still capable of offering a very respectable basshead impact and rumble way above the KZ ATE and very similar to the Seahf EG009.

Mids & Vocals
Mids of the Senfer UE are very warm and mediumly recessed on lower mids and lower vocals. Vocals could be felt somewhat congested at times but not as much as to sound muddy but neither they have the clearest lower vocals that you could ever hear. Higher mids are not recessed nor forward and do not fall into harshness. Overall their mids are well achieved for non-audiophile listeners. An EQ allows their lower mids to free up from most of the recession but if overdone they start to sound tinny; higher mids introduced some harshness.
Highs & Treble
The Senfer UE have enough brightness, not much detail or definition and can get piercing with strong high notes, usually they are not very sibilant (some mild sibilance is present at times though). Applying a custom EQ made them gain an incredible amount of detail and brightness, very high notes became a bit more piercing but sibilance remained under control and as sibilant as before using the EQ.
The Senfer UE do an excellent job regarding the amount of sound that leaks out of them, sound levels are very controlled and inaudible by nearby people even at mediumly high volume.
The UE are very capable of isolating from noises still with low volume levels, if higher volumes are applied they can offer outstanding isolation.
The custom shape of the Senfer UE is very well crafted and the ergonomics of the earpieces offer exceptional comfort and fit with no pain while offering a tight and secure fit at the same time. Like we have seen several times on other of our earphones reviews, the custom shape combined with the cable set above and around the ears add to the comfort and fit capabilities of the earphones like the KZ ZT, KZ ZS3, Seahf EG009, KZ ED12, Sound Intone E6 or the QKZ W1 Pro.
Response to Equalization
As you could read on our Bass, Mids and Highs section of this review, the Senfer UE were capable of greatly respond to any custom EQ that we threw at them. Despite the excellent response it is fair to recognize that it was not impeccable as some issues were partially enhanced. Highs outstandingly added brightness and detail but a bit more of piercing highs presence; mids significantly removed their lower recession with the con of some higher mid harshness added; bass had a crazy amount of increment of their mid-bass and sub-bass with no side effects.
