Since frequencies below 40Hz are very difficult to produce for small drivers, such as the ones used in most headphones, making an air-tight seal helps a great deal in lowering the LFE of headphones.
That's why most closed-back headphones especially in-ears usually have a much better LFE than open-back headphones, given a proper fit and seal. Standard Error for the Bass Range shows the amount of deviation of the measured bass response from the target bass response. P in Microsoft Excel. However, a perceptual weighting filter is applied prior to the Std.
They are more sensitive to the extension of sub-bass, which is determined by LFE low-frequency extension. The low-bass value is calculated by averaging the amplitudes of each frequency within the low-bass region.
The final value is then reported relative to our target amplitude of 90dB. This value can be considered as a metric for the "amount" of low-bass produced by the headphones, rather than the "accuracy" of the reproduction, which is determined by Bass Std. Since the low-bass region is where the most thump and rumble in sound come from, a headphone with a negative low-bass value would be perceived as lacking in low-end thump and rumble, and conversely, a headphone with a positive low-bass value may be perceived as having too much low-end and thump.
It should be noted that some users may prefer a bit of an elevated low-bass since it could increase the visceral feel of the headphones on certain tracks. The bass value, similar to low-bass, is calculated by averaging the amplitudes of each frequency within the bass region.
This value can be considered as a metric for the "amount" of bass produced by the headphones, rather than the "accuracy" of the reproduction which is determined by Bass Std.
The high-bass value, just like low-bass and bass, is calculated by averaging the amplitudes of each frequency within the high-bass region. This value can be considered as a metric for the "amount" of high-bass produced by the headphones, rather than the "accuracy" of the reproduction which is determined by Bass Std.
Since the high-bass region is where warmth and fullness in sound come from, a headphone with a negative high-bass value would be perceived as thin and lacking warmth, and conversely, a headphone with a positive low-bass value may be perceived as sounding boomy.
Out of the 3 bass regions, high-bass is the most sensitive to overemphasis and a little bit of excess high-bass easily muddies up the sound. Excess high-bass is a very common issue with certain types and brands of headphones. Most closed-back in-ears show overemphasis in the high-bass and low-mid region, which makes their sound quite muddy. Also, some open-back over-ears, especially the ones made by Sennheiser , have a distinct bump in the high-bass and low-mid region, giving them a warm and slightly muddy character.

He thinks for most people a properly fitting universal fit in-ear is more likely to sound better than a custom-molded headphone, but if a universal in-ear headphone's ear tips aren't providing a tight seal the sound won't match the designers' target frequency response curve. So if your in-ear headphones aren't doing a good job sealing out noise, you're not hearing their true sound quality.
Experiment with the tips that came with the headphone, but if they don't seal all that well, buy aftermarket tips. What about headphone impedance? Are low-impedance headphones -- under 32 ohms -- better than higher impedance designs? Home amps are more powerful than portable devices, and AC-powered amps produce more bass and tend to sound better with higher impedance headphones, like many Sennheiser and Beyerdynamic models.
With smartphones and portable music players, low-impedance headphones of 32 ohms or less are recommended. At home impedance is less of an issue, but Grell recommends higher-impedance models.
Next we covered sensitivity, a more sensitive headphone will play louder than a less sensitive one at the same volume setting on your smartphone or headphone amp. Unfortunately, manufacturers aren't consistent in the ways they define sensitivity. Again, since headphone makers aren't consistent with the way they create specifications, consumers can't compare one headphone spec with another to learn which headphone will play loud enough to suit their needs.
What about driver size? Do larger drivers sound better, play louder or make more bass than smaller drivers? Grell had a two word answer, "Definitely not. Grell says the maximum driver size should be around 42mm for full-size headphones ; with larger drivers the surface of the diaphragm physically changes shape at high frequencies and produces irregular frequency response. Larger drivers can generate cleaner bass, but less accurate high frequencies. The price of these bass headphones is usually on the lower side, although often they are not exactly cheap!
Haptic feedback creates a kind of fake sub-bass effect for want of a better way of describing it. Some people love it and some people hate it. We are not fans and we find it hard to believe that anyone who truly loves music would like haptic feedback! In our opinion, while some of them are reasonable for genres such as DnB, they lack any dynamic range and tend to get on your nerves if listened to for any length of time.
There are many reasons to stick with a flat frequency response. It sounds okay with most genres of music, and with others it is actually preferable. Perhaps because their hearing range has been destroyed by going to one too many ACDC concerts ;-. Anyone can and does… make flat response headphones.
Sure, a very high end set might sound a little bit better than a cheaper set but essentially flat response is flat response…. Unlike haptic feedback which aims to give the feeling of sub-bass we like headphones which actually have sub-bass! But you can feel them! As we get older, our hearing range tends to reduce meaning the lowest frequency bass we can hear goes up and the highest frequency we can hear treble goes down. Many Audiophiles believe that getting sub bass from a set of headphones particularly from in-ear headphones is not possible.
The bigger the driver, the easier it is to get bass and sub-bass response. A high quality driver speaker will typically have the ability to produce sub-bass in any high quality set of headphones.
The trick is to tune the bass first , then the highs, then the mids. With in ear headphones, the drivers are very small for obvious reasons.
