Sennheiser really pioneered a new type of driver design with their HD range. Instead of having the drivers angled perpendicular to your ears, these are positioned higher up and face at a downward angle to deliver the sound straight into your ear canal. Traditional headphones have always just thrown sound at your ear with no regards to their basic anatomy. The end result is a much cleaner and tighter sound.
Some other great technologies are the Duofol drivers. These eliminate the standing waves that cause so much loss of low end punch and vibrancy. Ultra lightweight voice coils are used to ensure snappy transients and a huge dynamic range. While these amy not be the bassiest headphones in the world, the bass you do get is amazing. It's deep, earthy and alive. If you feel a healthy bass boost is in order, then pair these cans with a good quality equalizer and/or headphones amp. While I would not call these headphones thin-sounding these two will even them out a bit for all you bass addicts out there.
Impressively the response for these headphones is from around 10 to 40k hertz. This beats the human ear itself which can only detect sounds between 20 and 20k. Pretty amazing. Another great thing about these is that they come with a little hanger to keep them at arms reach. If however you do find your phones getting beaten up and worn relatively quickly, then rest assured because Sennheiser still makes all their spare parts.
The tradeoff with open type headphones is that the sound is easily audible to everyone around you. Not so great if you are on the subway, at work or living with someone. However the increase in sound quality with this type of design makes it all worth it. The clarity, depth and dynamics are unmatched from closed design and it's one awesome experience. It's down to the physical design and there's no way around it unfortunately.
Sennheiser really hit it out of the park with the HD 595 headphones. These are top quality, high end and affordable headphones that will last along time and bring you years of fun and relaxation. The design, technology and features make the HD 595's perfect for classical and jazz fans or anyone seeking more good quality sound in their lives. Highly recommended. This is a great gift too by the way.

Our ability to hear is really important to us, it allows us to listen to our favorite music, and it permits us to listen to voices that can point out the presence of possible dangers. But the most significant factor of our hearing is the ability it offers us to listen to and effectively converse with different people, to hear and to discover. One of the main causes of hearing difficulties is due to being exposed to too much sound impulse.
We are all constantly subjected to loud noises, at home when we are doing work in the garden with a garden tractor, while cleaning the house with a vacuum cleaner or perhaps while preparing meals with a food processor or blender. Our ears can possibly endure it most of the time however when subjected quite often, particularly to severe excessive tones such as the tone of noisy engines on the manufacturing area when doing work or the earsplitting noise by a sniper rifle when target practicing could result to instant long lasting hearing damage, and after the damage is undertaken it could not be restored.
That's why we need to take good care of our hearing, by putting on hearing protection gears and gadgets. Depending on exactly where you intend to use it, you may select from several forms of hearing protectors, such as the standard earplugs and earmuffs or head phones. They work by simply lowering both the low and high frequency tones to a bearable level, typically to about 22 dB for earplugs and 27 dB for earmuffs or head phones. Many producers have brought it to the next degree and determined a system to protect you against many types of sound frequencies in a different way by working with a mixture of unique material for different applications.
For excessive sounds like when you are in a shooting range specifically if you are working with higher caliber rifles like shotgun, you must have a more advanced hearing protector similar to the electronic hearing protection. This specific complicated product is created to reduce just the undesirable sound created at selected pitch, just like the tone of the rifle and jet engines except the sound coming from a bursting glass, horn from a passing car and the voice of another persons.
This is done by employing a microphone and amplifier to reduce the dangerous noise and improve weakly sounds before it plays back to the built-in speaker virtually simultaneously. It's like a high speed repeater but filters the noises first prior to feeding it to you. It also has a sound level control so you can adjust the sound coming from natural conversation and the sound warning of impending threats. Both cups include its separate microphone to imitate the sound of the surrounding in full stereo, just like you would normally hear it in actual life. The device is power by four 1.5 volts AAA batteries which are perfect for about 200 hours of use. One of the widely known brands that most police force, armed forces and shooters preferred is Peltor which is designed by 3M. They have a full range of hearing protection from basic earplug and earmuff to a more complicated electronic head phones.
Basic Information regarding Sound and Noise: Sounds are vibrations that move through substances like air and water as sound waves. All sounds have two characteristics, the amplitude which determines the loudness of the sound and the frequency which determines the tone or pitch of the sound. Loudness is referred to as sound level or sound intensity that is measured in Decibels (dB). A whisper has a sound about 20 dB, standard conversational speech is around 60 dB and an air-driven drill is commonly over 110 dB. Problems takes place at about 120 dB and suffering can be experienced at over 120 dB.
