SENFER EN900 – Review



| 2 Balanced Armatures | 2 Dynamic Drivers |

? SENFER EN900, the latest and flagship model from the brand with a quad-driver configuration.

When the Senfer EN900 was announced it was not clear if they were a triple driver or a quad driver headphone. As reported by Senfer itself, the Senfer EN900 is a quad driver hybrid headphone with 2 balanced armatures + 2 dynamic drivers (it is also explicitly stated in their technical specifications on the packaging)

Besides the 4 hybrid drivers, the SENFER EN900 features detachable MMCX cables, with a metal cable bifurcation, metal mini plug section and a very fancy design.

The SENFER EN900 durability and construction quality is top-notch (Senfer has built quite a reputation for their highly solid-constructed earphones) with housings made of translucent plastics + metal. The inner housings are made of plastics but with a quality that is way more rugged than KZ plastics, for example.

The outer housings hold their most characteristic looks, the large metal grids. These metal grids have a great visual impact and add up to their premium feel – by the looks and design you would think that they have an open-back design but we will find it out later on. The overall aesthetics have a great resemblance with SIMGOT earphones, specifically the SIMGOT EN700 line.

Another recent multi-driver super-budget friendly headphone recently released is the KZ ZS10 but there is a very important difference between the SENFER EN900 vs KZ ZS10; the SENFER EN900 has 2 balanced armatures + 2 dynamic driver while the KZ ZS10’s 5 drivers are centered on balanced armatures with a configuration of 4 balanced armatures and 1 dynamic driver.

The SENFER EN900 soundtests will find out if this flagship model from the brand is up to Senfer’s high standards regarding sound quality.

The SENFER EN900 can be bought with a cable that holds an inline microphone or with a cable without any mic/remote, the price will be lower for the SENFER EN900 mic-less version.

The SENFER EN900 is compatible with Android and Apple devices.

Accessories & Packaging

The SENFER EN900 unboxing results in 3 pair of eartips (plus the pair already fitted), the detachable MMCX cable and a cable clip. The packaging is a simple cardboard box with a sliding cover that has a sort-of carbon fiber resembling finish.



Bass & Sub Bass

The SENFER EN900 bass is very well resolved with a fun, deep and punchy response that, still, does not get boomy or out-of-control. Nevertheless, expect a strong, very energetic and entertaining lower frequency style. Their bass is powerful and can cover absolutely any type of music genre, even the most bass-intensive tracks.

Applying an EQ, sub-bass gets crazy deep and also some extra mid-bass is added.

During our extreme bass tests the SENFER EN900 were able to handle 40% of the maximum power of a Fiio E12 amplifier while being set to high gain and with bass boost turned on; a custom basshead EQ was used. This extreme amplification and equalization made the SENFER EN900 achieve such a massive increment of mid-bass punch and sub-bass depth that they were able to reach basshead level impact and rumble way above the KZ ATE, Xiaomi Mi Pro HD or the SOUL K-POP but could not reach the level of the Elecom EHP-CA3580, Xiaomi Mi In-Ear Headphones Pro or the KZ ZSR, KZ ZST, Sony MDR-EX650, Sony MDR-EX800st and Pioneer SE-CX8.

Mids & Vocals

The SENFER EN900 mids are very warm and full-bodied. There is mediumly-strong mid-bass bleed, still lower mids do not sound too congested and are able to respond with an “alive” style. Overall they are warm and cozy sounding with a sort-of laid back sensation. Higher mids are crisp and clear and do not suffer from recession. SENFER achieved a good balanced of crispness that is usually not too harsh.

With an EQ their mids sound spectacularly, with a massive clearing up of their lower mids / lower vocals and an absolute removal of mid-bass bleed. Higher mids can be also spiced up with a crispness kick if wanted and they will answer back very well.



Highs & Treble

The SENFER EN900 highs are very bright and very detailed. Senfer is well-known for their bright highs and performance in this audio range, the SENFER EN900 is no exception. People looking for bright, clear and detailed highs will welcome this latest flagship model from the brand.

Usually the price paid for very bright and detailed highs is piercing and sibilant peaks; the Senfer EN900 does not present excessive piercing highs but sibilance is recurrent.

If you correctly EQ, they will smash you with an insane amount of detail that could had never imagined that was there and their brightness levels will also become out-of-this-world. Strangely, their piercing highs do not get too empowered; do expect substantially stronger sibilance.




Sound Leak

The sound that leaks out of the SENFER EN900 is noticeably subdued, despite their sort of semi-open back. They will allow private listening sessions even at moderate volumes.
