Product Launch : Hisenior Febos Fe3U

IEM market is still on the rise, demand for good quality “Value for Money” earphone is growing every day. Chinese brands are leading the way with a lot of new entries into the market. Those who existed are introducing earphone in new price brackets and different target consumers.

HiSenior has been making a lot of waves in the entry level market with their T2U dual BA earphone which is priced at just $80. And guess what, they have another $80 IEM which has 5BA drivers per side. They have a whole array of IEMs starting a just $60 going as high as $819 for the flagship MG12U for universal earphones. They have a range of custom IEM, a bit more expensive than the universal trim. Most of their IEMs are bang for buck, for an instance, it is hard to find a 8BA IEM for under $200 but HiSenior has the B8 at just $199.

Now HiSenior has introduced a premium range of IEMs under their sister brand “Febos” and Fe3U is the first IEM from them. (with plans for Fe6U and Fe8U in future). It uses 3 BA drivers, one for bass, mids and highs each, incorporated in a 2 way crossover. It is available in only one color and is priced at $199.

Consumers are impressed with the HiSenior T2U thanks to its “bang for buck” prospects. The Fe3U is not really cheap though. Priced at $199 HiSenior is projecting Fe3U as a more premium earphone. They are not leaving any stones unturned by comparing its frequency graphs with Shure SE535, one of the older but most successful earphones in the market. The graph of the Fe3U is more linear and doesn’t have the upper treble roll off seen in the SE535 graph.


There are a lot of earphones in this price range, BGVP DM6, ISN H40, DUNU SA3, Spring 2 and many more, one can only imagine the volume of IEMs dwelling in this price range. HiSenior is trying hard but it remains to be seen how it fairs in the market.

My humble audiophile journey started in 2010, when I was in college, where I fell in love with the elements, nuances, and variations of this mesmerizing world. The ability of tiny earphones to recreate amazing sounds made my bad days tolerable and good days better! Now I am a full-time audiophile with a preference for musical tracks, especially vocals and engaging ones. I must admit I am addicted, but not to drugs or alcohol, but to earphones. Come join me as I share my experiences, bad or good, and let’s have some fun!
