This isn’t paid for by any company, nor am I sponsored by any of the below corporations. The reason why I purchased the below headphones? Well going back to the previous post on the scientific article I had written; these headphones fall within the category of the most physiologically advantageous headphones based on factors such as frequency, sensitivity and my overall perception of sound.

Zinsoko 897 Ample Wireless Headphones
Price: $50
Driver Unit: 40.0mm
Frequency Response: 20Hz – 20kHz
Impedance: 32 Ω
Sensitivity: 97dB/1mW
Max. Input Power: 20mW

These headphones pack great power and have an efficient size. 40mm drivers boost the Zinsoko 897’s broad range of sound for your listening pleasure. The design of these headphones is very sturdy and built to last. While other headphone companies skimp on the functionality of a well constructed headphone, Zinsoko has innovated a design that not only accomplishes this but creates a style all its own as well. It takes 2 hours of charging time for up to 20 hours of extended use. The noise cancelling feature that it has mimics that of very expensive “Bose” headphones. This feature subtracts the frequency of external sounds from the output of the sounds being heard. These feature a built in microphone for gaming or taking a quick phone call in between listening sessions. They fold away easily and aren’t “bulky” like many Wireless Headphones on the market. https://www.amazon.com/dp/B01JKTOE4Y

Panasonic RP-HTX-7
Price: $39
Driver Unit: 40.0mm
Frequency Response: 7Hz – 22kHz
Impedance: 40 Ω
Sensitivity: 99dB/1mW
Max. Input Power: 1000mW

Amazing headphones for anything from listening to recording in a studio. The material on the earphones is very rubbery and seems that these headphones would be highly resistant against sweat. These headphones have a retro and stylish look. They also come in a variety of colors for both of the housings and the headband. This single wire design shows to be very durable and each side of the headphone is protected by a tough plastic shell. Only problem is keeping these on “too tight” will unnoticeably create some physical pain to the outside of your ears but that is simply one thing to be aware of. This isn’t a bad thing because if you did decide to go “running” with these on, they would probably stick to your head. These make for a great general and versatile headphone. After repeated use and wrapping these up and throwing them in a suitcase, very little wear and tear occurred. Great for listening and monitoring sounds to get a great general dynamic. Very heavy mid-range and great for listening to all genres of music. The cable on these have a 1/8” plug making it suitable for your Smartphone or Laptop.

JVC HA-M55X
Price: $50
Driver Unit: 50.0mm
Frequency Response: 8Hz – 23kHz
Impedance: 36 Ω
Sensitivity: 107dB/1mW
Max. Input Power: 1000mW

Great for sound mixing or listening to music.Very Bass heavy but physically the only problem ailing me is the dual wires (one coming out of each ear phone.) The design presents itself with a lot of unnecessary plastic and a very thick considering the size of the drivers. The upside of this is it gives the headphone some protection against any drops or damage. The sound was a bit surprising as I expected a stronger output and more mid-range but not disappointing at all nonetheless. As the volume increased they did not create create distortion and as I pressed them closer to my ear (as they do have lots of padding) I did not notice a very large change in the dynamic. The cable on these have a 1/8” plug.

Shure SRH-750DJ
Price: $149
Driver Unit: 50.0mm
Frequency Response: 5Hz – 30kHz
Impedance: 32 Ω
Sensitivity: 106dB/1mW
Max. Input Power: 3000mW

Great for “DJing.” and physically not taking up a lot of space. Due to the width of these cones (like common DJ headphones, this makes the compression of sound slightly quicker and less roomy.) Professional design as the connector is removable and includes a 1/4 inch adapter that “screws” on or can be left off to have a 1/8” plug. These also came with extra ear pads and a carry bag. The connector is removable that connects to the headphones so that if you cable wears out a replacement one is about $15 and it plugs right in. Physically after heavy use I did notice the plastic becomes slightly “squeaky” and has the potential to fall apart with some slight abuse. These outweigh there competitors due to the clarity and sound isolation that other brands fail at. Suitable for DJs because the size of the phones are so thin that when one side is “flipped” the sound coming out of the opposite earpiece is inaudible. Overall these do isolate the sound very well.

Here is an article worth reading! This article is on “Frequency Theory” and is something that many of you should read and consider when buying your next pair of headphones or speakers. Personally and scientifically the best pairs of headphones start at 8 Hz (The same frequency that dolphins communicate at) as well as finish at 22.5 kHz (The end threshold of most humans hearing.) Your ears are very important, and this article cross references a lot of data showing how important they play in various physiological functions.

This can be found on the University of Claremonts STEAM scientific journal. This was my first publication in a scientific journal, titled “The Threshold of Hearing”: http://scholarship.claremont.edu/cgi/viewcontent.cgi?article=1098&context=steam
