Audio-Technica ATH-ANC7b Headphone

[Charlton]

The classical open headphones for the home are totally unsuitable for music on the go, for neither gain nor adequate source of so portable. But here has already done a lot: almost all MP3 players support lossless compressed file format (lossless), which now ranges from space for many of listening to these formats, and there are a wide range of headphone amplifiers for mobile use. Audio-Technica is back with its latest handsets in the form of the ATH-C101. Available in 12 different colors, these headphones feature 18 - 22,000 Hz frequency response with a sensitivity 102dB/mW (16-Ohm impedance).

Weather you enjoy music or TV, but there is no way that your headphones isolate you from the environment, and they do not want to resort to expensive units designed for DJs, maybe you should take a look at the proposal of Audio-Technica. ANC7b With headphones, the manufacturer ensures that the user will notice a reduction of ambient noise figure at 85 percent, something that is supposed to guarantee their own system of Audio-Technica QuietPoint has christened.

In addition to this system, Audio-Technica no details regarding its operation, the sense of isolation that is achieved with these ANC7b is implemented by an audio output of 109 decibels. This power, but it ensures 50 to 60 percent of total capacity output quality can be highlighted by the user, may be excessive for those who wear your (if the result does not drag its maximum state distortions .)

On the other hand, these Audio-Technica headphones ANC7b are wireless to allow the addition of a cable with 3.5 mm, if we do not want to crush the AAA battery it needs to function without physical connections. In this case, the empowerment of the headphones will be about 40 hours. In addition, the manufacturer seems to have endeavored to comfort when wearing these headphones, because its weight is 240 grams, which is not bad for this type of device s.

The Audio-Technica ANC7b, who is already on sale, can be purchased at a price of $ 220. I recently bought a headset with active noise canceling Audio-Technica ATH-ANC7b. I needed headphones that I could protect you from the office of noise, because it is very annoying. Headphones ATH-ANC7b equipped with active noise control - locked up to 90% of external noise (20 dB). Combined with friendly head design ear cups with soft padding, it allows the user to enjoy their favorite music, without distraction by extraneous noises.

Sound Quality

Ideal for use with MP3, CD, DVD & in-flight entertainment systems, ATH-ANC7b QuietPoint closed-back headphones deliver clear, high-resolution sound, with impact bass, a detailed mid-range, extended treble and accurate imaging in an immersible sound field. Their ear cups have been redesigned for greater comfort, with generously cushioned padding and a shape that fits easily over any ear. The quality of sound will take care of 40-mm speakers on the basis of neodymium magnets, capable of reproducing frequencies from 10 Hz to 25 kHz. Signal to noise ratio (sensitivity) of 109 dB. Bundled with two headphone cables, length 1 m, 1.6 m and a protective carrying case.

The ATH-ANC7b QuietPoint headphones feature large-aperture 40 mm drivers with neodymium magnet systems and extremely high 109dB sensitivity to provide generous volume levels from any music source. The headphones also work when the noise-canceling function is turned off, and operate in passive mode without batteries. Noise-canceling electronics are fully integrated in each earpiece, with no need for external modules.

This model replaces the former is already well-established model ATH-ANC7. Like its predecessor, ATH-ANC7b equipped with an active noise control, but in this model can block up to 90% of external noise (20 dB), in contrast to past 85%. Combined with friendly head design ear cups with soft padding, it will allow the user to comfortably enjoy your favorite music, without distraction by extraneous noises. Thus, the user will hear only the music, with high quality. This will take care of 40-mm speakers on the basis of neodymium magnets, capable of reproducing frequencies from 10 Hz to 25 kHz. Signal to noise ratio (sensitivity) of 109 dB. It should be noted that included headphones are supplied with two cables - one meter in length and 1,6 meters and a protective carrying case.

Surround Sound

The music in this headphone loudly turned so that one still hears only. But this is the worst of all decisions. First, it makes no joy so his fellow man, because not everyone shares their own taste in music, and - perhaps more importantly - their own ears to sounds as far too quickly to high volumes over a longer period. (The hearing aid industry will achieve high growth rates determined in the coming years, if I deceive not my observations in public transport). But anyway who loves ears and hearing (and who start to delve into HiFi heard certainly help) for this is not an option.

The second approach here sounds more interesting: the ambient noise is reduced so that you can hear the music well in a normal voice. These are the passive approach, which includes the traditional headphones and closed depending on the model can already achieve good results. The best isolating earphones, however, are usually also the bulky. Interestingly, however, is the more famous and more popular in-ear earphone, which almost completely seals the ear canal. Unfortunately, not everyone comes to terms with these devices. What makes us ultimately to the last and probably most recent development in this field brings: the active noise reducing headphones (active noise-canceling, in short, NC).

The principle is physically quite straightforward to implement but quite expensive. Each sound consists of pressure fluctuations in a particular frequency. If one takes this noise now with a microphone and can play an opposite phase to sound, so wave crest meets trough and the air pressure fluctuation is damped - ideally even completely wiped out. This is exactly what is now trying to reach the NC headphones. Noise is added and anti-phase anti-sound production, so that less noise arrives at the ear. This will only work well at low frequencies - in the high-frequency interference sources to build all the headphones continue to passive damping.

Of course we think first, headphones have an inestimable advantage over the traditional hi-fi system: they are usually small and portable and can provide not only at home for music enjoyment, but are easily taken to get the go indulge in the most beautiful sounds.

Support and Advantage :

The problem is known: To listen to a DJ undisturbed monitoring and as a drummer backing track, click and a Bassdrum signal, it is necessary that closed headphones sound environment possible not for the ears (or weaken their maximum possible). The easiest way is too passive damping, i.e., the ear-shells and beads to make it as strong as possible. The need for a strong damping, the music-making, however, is not alone. But to see these monsters a lot like an air traffic controller. No wonder, for such a jet engine is known to be far from a quieter option. From the aircraft technology is therefore also the technology, "active" to attenuate. This is not particularly new, but has been used since the fifties.

Audio-Technica ATH-ANC has with her so invented no technology, but use them only. A well-known German tradition manufacturer of headphones and microphones in aviation well in business, but has so far not made any great attempts to align its products in the relevant market for us - this was more to the intercom Subject to market with the appropriate headset.
Sound is well known, a vibration that is transmitted through a medium (usually air). In a theoretical description of the simplicity is often a single frequency, so use a sine wave. Two sine waves superimposed on the same frequency and same amplitude (that are added together), the result depends on their phase position. The starting points of the two oscillations are identical, you can base on the graphic indication of what happens.

The amplitude doubled (simple terms: The volume is also doubled). Starts the second sine speaks exactly one half oscillation cycle (1/2T) after the first one by a phase shift of 180 ° (because 360 is a full circle turn). This 180° can often be read in mic, even if it technically is not entirely correct. This change of the second signal is not achieved by some delay, because this would have to be different from high (since the last signal which is different lengths for all frequencies). The chart reveals how this shift can be achieved much easier and for all frequencies: the second signal only needs to reverse polarity (i.e. positive and negative are reversed). These so-called inversion works terrific!

Similar Headphones :

Audio-Technica is something unknown, however, at least in connection with headphones for private users. In Japan, however, the company has long been known for unusual and extremely high-quality headphones in the absolute top segment, so just enjoy many models are also limited to high international popularity. Now Audio-Technica will officially bring more products to market outside of Japan and the ANC7b (successor of the ANC7) is one of those listeners. Audio-Technica calls his NC system Quiet Point.

They practical travel cases, where the headphones can be possible to save space and transport it safely with all the important accessories. Another exception involves a number of adapters for 6.3 mm connectors and 3.5 mm double mono airplane plug a standard accessory. This type of headphone has detachable cable to use them without music only for noise reduction. Audio-Technica ATH-ANC7b: The Audio-Technica has a simple shell on the left sliding switch to activate the NC system. A blue LED gives information about the current mode and the battery condition. On the right side is the battery compartment which is filled with a classic AAA battery. The subject is very well positioned in a rotatable cap. When closed, the tray is not quasi identify - a small but effective face lift over its predecessor.

The ear pads of ANC7b are more solid, which on the one hand slight disadvantages in terms of comfort with it, on the other hand offers a very good damping. The pillow is very thick and contributes significantly to the good comfort. Overall, the Audio-Technica makes a good impression - no wobbles, and it can be easily and safely stowed or set.

Phiaton PS 300 NC: The Phiaton is equipped with two switches on the left shell. The upper activated the NC - there is also a blue status LED - and the lower switches an additional bass boost on or off. The NC switch is unfortunately positioned below the bracket, so that it is on the head sometimes obscured by it. If you want to switch without removing the headset, you must fumble Sun sometimes a little.

The battery is located in the right shell. Phiaton ships with two batteries with the headphones that fit exactly the form in the headphones. The charger for the battery has the same shape as the ears - a nice detail. The charger can be either directly via USB to a computer or the included USB adapter. This provides Phiaton a wide range of connector types with the same - a model for travel headphones! The supplied cable has a print button, which can block the transmission of music, to capture, for example, ambient noise, or a call - can very useful to the seat of the headphones do not have to constantly refocus. The ear pads are soft and pleasant, and the headset sits very lightly on the head.

Sennheiser PXC 450: The Sennheiser has four buttons on the right ear (switch, talk-through and volume plus and minus) and the status LED. This is red while the NC and green when the talk-through function is enabled. It also warns when battery almost empty. Hidden beneath the bracket is in the right shell, the battery compartment, which is also filled with an AAA battery. In addition, located under the handle for a sliding switch to bypass mode (passive mode). The headband and ear cushions are soft and comfortable lining to ensure a high comfort, despite the expansive size of the Sennheiser. The materials and buttons act consistently high quality and provide a good overall impression.

The talk-through function that allows blocking on a button to play music, and instead the signal of the audio is played. The idea is so simple and practical: All the technology to exist and even in well-insulated headphones it is great to enjoy your music to and the next moment the announcement in the airport to understand clearly and distinctly, without removing the headphones only need .

Conclusion :

Closed Headphones Audio-Technica ANC7b ideal for travel - built-in active noise control system will provide protection from external noise on the road, reducing their levels by 90%. A cutting-edge technology used for the accurate transmission of all the nuances of music, the listener guarantee sound level Hi-Fi. This enhanced version of the model ANC7, with higher levels of noise reduction - up to 20 dB.

The Audio-Technica ATH-ANC7b however you get a headset, which probably brings out the greatest possible to have the concept of the soundproof headphones - and without the size to put an industrial hearing protection on the head. The good sound quality in conjunction with the very high damping for maximum music enjoyment even in difficult environments. The stage presentation is held strongly left, right and center, and the detail resolution - one of the strengths of many Audio-Technica listeners - is not very high, the focus was primarily on the likely noise reduction.

Foldable headphones active QuietPoint ATH-ANC7b can be carried away everywhere. It comes with a detachable cable (remove operation mode noise without audio) with mini-connectors 3.5 mm to 6.3 mm adapter, a special adapter to connect to flight entertainment systems and a convenient carrying case.
