Recently released this summer, the Headphones 700 are the best wireless over-ear headphones that Bose has to over. The combine the best-in-class noise-cancellation with great audio quality. Other than the design overhaul, the biggest difference from the QuietComfort 35 II is that the Headphones 700 have a significantly upgraded microphone array. This allows the headphones to have a wonderful tranparancy mode (or ambient listening mode), and makes maybe the best headphones you can buy for call quality.
If you have a bass problem you could find a filter of some kind that cuts the low bass. Some bass controls can do that. I haven’t found a music genre that totally lacks strong bass, although “acoustic” sometimes doesn’t have strong bass. Mainly, you should make sure your system is matched properly with amp and headphone, so the different frequencies are in balance. Then you will have better luck with different music.
Dale: It’s really the same with any genre or sub-genre of music, that the sound from different artists and tracks can vary a lot, so having more than one headphone is a plus. When only one headphone is available at a particular time (portable use especially), one option is to use a headphone that can accommodate a wide range of genres, in which case there may be compromises to consider. Another option is to carry two headphones – one on the head or around the neck and another in a carry case. Some of the small headphones can make this easy to do.
At the heart of the WH-1000xM3 is outstanding wireless sound. Sony’s LDAC technology delivers a wireless signal at what the company claims is three times the quality of standard Bluetooth streaming, and the headphones also support the latest aptX HD codec (with supported devices). The 1000xM3 even “upscale” wireless music from high-resolution audio devices using a special chip, helping to make music sound dynamic and beautiful, with authoritative bass and clear treble response held together by a well-rounded midrange.
An electret driver functions along the same electromechanical means as an electrostatic driver. However the electret driver has a permanent charge built into it, whereas electrostatics have the charge applied to the driver by an external generator. Electret and electrostatic headphones are relatively uncommon. Original electrets were also typically cheaper and lower in technical capability and fidelity than electrostatics. Patent applications from 2009-2013 have been approved that show by using different materials, i.e. a "Fluorinated cyclic olefin electret film", Frequency response chart readings can reach 50 kHz at 100db. When these new improved electrets are combined with a traditional dome headphone driver, headphones can be produced that are recognised by the Japan Audio Society as worthy of joining the Hi Res Audio program.

A. Near-field communication, better known as NFC, is a wireless connectivity protocol similar to Bluetooth. NFC uses less power than Bluetooth and is faster when pairing devices, but it only has a range of about four inches. Some headphones use NFC technology to drive the process of pairing headphones with smartphones, but because of the range, it’s not used to transmit sound. While both Android phones and iPhones include NFC chips, it’s not accessible in Apple devices, so if you want a pair of headphones with NFC, you’ll need to own an Android phone to take advantage of the faster pairing.

Supra-aural headphones or on-ear headphones have pads that press against the ears, rather than around them. They were commonly bundled with personal stereos during the 1980s. This type of headphone generally tends to be smaller and lighter than circumaural headphones, resulting in less attenuation of outside noise. Supra-aural headphones can also lead to discomfort due to the pressure on the ear as compared to circumaural headphones that sit around the ear. Comfort may vary due to the earcup material.

The rule that I use is that the bigger the size of the headphone, the bigger the need for amplification. Of course factors like driver sensitivity and impedance will matter, but the general rule of thumb is, use a dedicated headphone amplifier for a full size headphone. Even a portable amplifier can be enough, depending on the type of the headphones.
Semi-open headphones, have a design that can be considered as a compromise between open-back headphones and closed-back headphones. Some[who?] believe the term "semi-open" is purely there for marketing purposes. There is no exact definition for the term semi-open headphone. Where the open-back approach has hardly any measure to block sound at the outer side of the diaphragm and the closed-back approach really has a closed chamber at the outer side of the diaphragm, a semi-open headphone can have a chamber to partially block sound while letting some sound through via openings or vents.
I already own a few headphones, namely the Audio-Technica ATH-Pro500MK2, ATH-T500, Sennheiser PX 100 II & PX 200 II, and the Philips Downtown and Uptown (Rule #3). I’m thinking of adding a new one and I can’t decide between the Beats Solo 2, Grado SR80e, and Sony MDR-10RC (budget constraints). I listen mostly Pop/Rock and Classical music and I have a cheap (Fiio E06) headphone amplifier.

For older models of telephones, the headset microphone impedance is different from that of the original handset, requiring a telephone amplifier for the telephone headset. A telephone amplifier provides basic pin-alignment similar to a telephone headset adaptor, but it also offers sound amplification for the microphone as well as the loudspeakers. Most models of telephone amplifiers offer volume control for loudspeaker as well as microphone, mute function and switching between headset and handset. Telephone amplifiers are powered by batteries or AC adaptors.


Headphones are available with high or low impedance (typically measured at 1 kHz). Low-impedance headphones are in the range 16 to 32 ohms and high-impedance headphones are about 100-600 ohms. As the impedance of a pair of headphones increases, more voltage (at a given current) is required to drive it, and the loudness of the headphones for a given voltage decreases. In recent years, impedance of newer headphones has generally decreased to accommodate lower voltages available on battery powered CMOS-based portable electronics. This has resulted in headphones that can be more efficiently driven by battery-powered electronics. Consequently, newer amplifiers are based on designs with relatively low output impedance.


Over-ear and on-ear headphones effectively block out outside sounds, allowing you to hear your music or whatever else you're listening to crisply and without distraction. Over-ear headphones are sometimes known as full-size headphones because they completely envelop the wearer's ear. This results in what's known as passive noise reduction, which makes these some of the most-preferred headphones available. The only drawback is that your ears and the skin around your ears can get warm and sweaty. These are usually the heaviest type of headphones.
