The drivers, whereas wonderful at reproducing vocal vowel sounds, the lows, because of the excessively miniature measurement of those buds, do certainly endure. What you achieve in miniaturization, you lose in richness of sound. The excessive frequencies additionally appear to roll off too abruptly within the audio response.  As we write this, we’re listening to Shania Twain’s “Any Man of Mine,” nation waltz music, and thru these stereophones, the kick drums, that ought to dominate the music in the course of the verses, sound like a child tapping slightly pencil on a desk; the deep bass barely perceptible.  With our iPad Mini 2 equalizer on flat, the shortage of excessive finish (weak symbols and S and T vocal sounds) reminds us of the AM radio listening days, the excessive frequencies above 5 KHz are utterly attenuated.

However on a constructive observe, these earbuds settle for boosted bass and treble from an equalizer at fifty % quantity ranges, with out noticeably distorting. So you possibly can restore the lowered ends of the audio spectrum bass in case your media gadget has an equalizer.  Additionally, the noise isolation properties perform properly to considerably scale back surrounding ambient noise from reaching your eardrums whereas listening to pop, rock, and nation music.  However inadequate acoustic noise shielding right here renders the KEB30Okay earphones not nicely fitted to the quiet passages of classical and a Capella items.  For the informal mainstream music listener nevertheless, the KEB30Okay buds work fairly properly.

Disadvantages, Issues, Cons, Limitations, and Considerations about Koss Earbud Headphones KEB30Okay 

No Twine Slider

This might allow adjustment of how massive the Y cable joint is, the place the left and proper ear driver cables come collectively into one. Such a function augments consolation and reduces catching and snagging on garments buttons and zippers, and as low cost as it’s to implement, actually ought to seem on all earbuds.

In Ear Design Means Much less Sharable

They’re extra apt to turn out to be dirty with ear wax, which you will want to keep away from transferring from individual to individual by sharing these buds.

Quantity Management Topic to Failure

Because the quantity degree setter here’s a variable resister, it may possibly develop into soiled and  “staticy,” and fail after a a lot shorter time than the extra superior, software-regulated, pushbutton controls of headphones with full distant management features inbuilt.

Straightforward to Harm Ears

Watch out although, to not blast them too loudly, as a result of they will generate sufficient quantity to masks out exterior feels like vans coming. We’d advocate towards enjoying these whereas strolling alongside and throughout busy roads, as a result of whereas they nonetheless permit in a lot exterior sound, they nonetheless, notably whereas enjoying your music loudly, might forestall you from listening to approaching automobiles.

Additionally, these buds produced considerably larger ranges of notably distorted audio than the unique iPod inventory buds.  Observe that these buds sound considerably harsher and “cheaper” than Apple’s present inventory earbud choices.

Scale back Outdoors Noises

Since these buds “cease up” the ear canal, they considerably scale back outdoors noises from being heard whereas listening. So you could not understand essential sounds (like your child crying or husband calling).

Might Annoy Vacationers Close to You

However, because the diploma of sound isolation is reciprocal (works equally as nicely (or not) for protecting inner sound in whereas fencing exterior sounds out), and the KEB30Okay doesn’t hold the music contained in the ear very nicely. Some media sounds escape to the surface by way of the rear ports.  So you could disturb close by passengers on trains and planes, when you play your music too loudly.

Probably Not Fixable

Given the very small audio cables and connections right here, these earphones can’t be repaired virtually, because the wires inside are hair-thin. So as soon as they break, they’re completed. No biggie for el cheapo earbuds like these. However we’d nonetheless favor that our earbuds be repairable ought to they fail, the costlier they turn into.


  • Frequency response: 15 – 20,000 Hz.
  • Sound strain degree: 109 DB.
  • Impedance: 16 ohms.

Our Score

We price the Koss KEB30Okay Noise Isolating Earbuds at 75 out of 100. Very removed from the perfect earbuds, they’re among the many lowest priced. Their sound high quality equals their low value.  They will fall out of ears too typically and require frequent changes to maintain them correctly positioned. Whereas they’re nice for teenagers and newbie listeners, you’d definitely develop uninterested in them shortly. So we decline recommending them to any audiophiles or refined music listeners, to a different. *grin*
