Koss KEB40 Earphones Reviews

Koss, an American aggregation acclaimed for their Porta Pro headphones accept clearly fabricated their absolute agency accessible in India. We’ve in actuality advised the KSC75 clip-on earphones, which offered a appropriate alert acquaintance for the price. Today we accept the KEB40 In-ear phones, which are targeted at anyone searching for bigger complete abreast and portability. These aren’t absolutely cheap, so let’s see if they are able to absolve the price.
Design and Features
The KEB40 earphone drivers are encased in an aluminium enclosure, which makes them actual abiding and would calmly survive adventitious drops or even if you footfall over them. The buds accept a little elastic ring about them to accord you a acceptable anchor while putting them on. The earphones appear with three altered sized silicone ear-tips in the box. The superior of the silicone is nice and blubbery with just the appropriate bulk of adaptability to accommodate acceptable complete isolation. Sadly, the aforementioned body superior does not transcend to the cord. They attending and feel actual attenuate and breakable and get circuitous up actual easily. They do appear with a cord-slider acceptance you to acclimatize the balance baggy from the cable. The 3.5mm adapter is gold argent as able-bodied and is beeline (not L-shaped). The breadth of the cable is 4ft, which is affluence for even a actual alpine person.

The KEB40s affection a 9mm disciplinarian with a rated abundance acknowledgment of 15 to 20,000Hz. It has an Impedance of 16 Ohms, which is nice and low, so your buzz or MP3 amateur will calmly be able to drive them afterwards any issues. The fit of the in-ear phones is not actual close at first, some accomplishment is needed. Once in, the complete abreast is appealing acceptable and it manages to block out a lot of ambient noise. Since it doesn’t blow adjoin your ears, it looks a bit odd with the affairs afraid out at appropriate angles to your face.
Performance
The aboriginal brace that Koss beatific beyond had a actual aerial and alveolate complete to them, so we asked them to forward addition assemblage cerebration they maybe defective. Oddly, even the additional brace they beatific articulate appealing abundant the same. Despite auspiciously blocking out a lot of ambient noise, the aggregate levels were absolutely low, which meant we had to bang it up absolutely a bit, but even at best volume, it acquainted low. The KEB40s abridgement a acceptable bulk of bass, which is actual attenuate even in Trance and Hip-Hop tracks, admitting in others like Classical or Lounge, it’s about non-existent.

We activated the Koss application a Samsung Galaxy S with Voodoo Control Plus and PowerAmp. Before starting the analysis we kept the earphones for a 24hr burn-in cerebration that would help, but acutely it didn’t work. Even afterwards arena about with the equalizers, we were able to get some appropriate levels of mids and highs, which were clear, but overall, the music articulate collapsed with actual little bass. The bearings bigger a bit if affiliated to a notebook, but not by much. In the end, it didn’t amount what antecedent we used, the KEB40s just weren’t able to bear on any front.
Verdict
With a ample bulk tag of Rs. 2,400, these are too big-ticket for the affectionate of achievement they deliver. Earphones such as the SoundMAgic PL11s action abundant bigger audio achievement and are bargain at just Rs.550. What Koss accept managed to actualize are some absolutely big-ticket brace of earplugs, because afterwards acceptable audio fidelity, that’s what they about are. We acclaim you abstain these in-ear phones and stick with something approved and activated like the Creative EP630’s for bass active or PL30s from SoundMagic.
