hi? i want to ask a question. Im a complete newbie on the audiphilic side so i red on a site that the more the impedance is higher a headphone amp is requierd and less the impedance a headphone amp is not that much requierd cause the headphones with less impedance are made for portable players. Now let me get to the point im using cheap headphones the philips sbc hp250 they are old about 5 years and sound ok but i want to replace them so i use them mostly for listening to hours of music and i am also a musician so would it make a diference if i would buy a behringer headphone amp http://www.amazon.com/Behringer-HA400-4-Channel-Stereo-Headphone/dp/B000KIPT30/ref=sr_1_6?ie=UTF8&qid=1379715994&sr=8-6&keywords=behringer+amplifier and amplify those headphones would they play better cause now im having them plugged on a intergrated via vinyl soundcard http://www.via.com.tw/en/products/audio/codecs/vt1708s/. and they sound shitty on full volume. I am considering to buy new full size headphones and im willing to give max 80 euros for them so for the start i just want them to be loud but i want a clear sound at high volume levels. To be more specific i want a clear sound that is balanced in the lows mids and highs but not distorted and the lows should not be too much overpowered. I was sniffing around your site and found some sennheiser hd 202 ii they are not even close to 80 euros but i heard they sound great would they be better than these philips headphones and what other alternatives would you suggest me for max 80 euros
AAC has some advantages when it comes to latency, but we recommend avoiding this if you care about audio quality. We found high levels of noise and lower than average frequency cutoffs—both unacceptable to audiophiles and younger listeners. Though the sound isn’t as bad as some may make it out to be, the shortcomings are noticeable to the human ear at normal listening volumes.
The problem is made even worse by the fact that Android phones can’t handle AAC in a method that approaches Apple’s performance with the codec. Consequently, we will no longer be recommending AAC-only headsets here at SoundGuys, as the experience is that broken from source to source. The results are crappier and noisier than the other codecs by a longshot.
Circumaural headphones (sometimes called full size headphones or over-ear headphones) have circular or ellipsoid earpads that encompass the ears. Because these headphones completely surround the ear, circumaural headphones can be designed to fully seal against the head to attenuate external noise. Because of their size, circumaural headphones can be heavy and there are some sets that weigh over 500 grams (1 lb). Ergonomic headband and earpad design is required to reduce discomfort resulting from weight. These are commonly used by drummers in recording.

Interestingly, yesterday I was comparing my beyer 770 with my AT ath30 and then I realised how important it is also the soundstage, the good separation of instruments … finally I have decided I want to take this into account as well, and not only the issue of bass, midrange and treble … Since, in my opinion lack of bass we can try to fix it, but lack of soundstage is impossible, right?
We use a commercially-available Bluetooth high-def interface with an S/PDIF output to test the Bluetooth output of four flagship phones. This way, we’re able to record test signal output and compare the datasets with our in-house analysis software. We kicked the tires on a 96kHz/24-bit test file to see how Bluetooth handled high-bitrate music, as well as normal 44.1kHz/16-bit files to see how each codec treated CD-quality streaming audio. We then measured the recorded sample against the original file. We used both lograrithmic sine sweeps, and complex signals like square waves in order to provide a more realistic set of tests for how people actually use Bluetooth headphones.
Dirac is mainly for resonance (narrow band) taming and not suitable for normal EQ. Accudio is good. But since the L1 already has a strong bass emphasis, boosting mids or treble just makes the imbalance worse – i.e. the freq. response becomes more ragged and the sound more harsh. To get a smoother sound and better mids and treble, reduce the bass instead.

What I’m saying here is that it’s better to own three $100 headphones than one $300 headphone. Or three $300 headphones than one $900 headphone. Why? Because most people don’t limit their playlist to strictly one genre. And following the logic from Rule #2, the right headphone-music pairing is going to be better than one expensive headphone paired to the wrong music.
The design is not mechanically stable; a slight imbalance makes the armature stick to one pole of the magnet. A fairly stiff restoring force is required to hold the armature in the 'balance' position. Although this reduces its efficiency, this design can still produce more sound from less power than any other[clarification needed]. Popularized in the 1920s as Baldwin Mica Diaphragm radio headphones, balanced armature transducers were refined during World War II for use in military sound powered telephones. Some of these achieved astonishing electro-acoustic conversion efficiencies, in the range of 20% to 40%, for narrow bandwidth voice signals.
The company is well known for bringing noise-canceling headphones to the general public — the QuietComfort Acoustic Noise Cancelling headphones were released in 2000 — and since then, it’s only continued to churn out industry-leading noise-canceling headphones. Its most recent iteration, the Noise Cancelling Headphones 700, might just be the best noise-canceling headphones, ever.
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.
With small extrusions emerging from otherwise understated wireless in-ears, Jabra’s Elite Active 65t look like miniature versions of the Bluetooth headsets that helped put the brand on the map. But don’t be fooled by the looks — with sweatproofing, excellent sound quality, and a myriad of useful features, these little guys beat out every other pair of headphones on the market as the best workout headphones.
The DT770 is fine – not basshead, the COP is the same size and configuration as the 770, and both of those, large though they are, are “tighter” built so they feel less clunky than the M50. But the biggest problem for you is that the smaller headphones under $200 almost all have a steeply rolled-off treble, which is trouble for the more refined type of music. One possible exception is the Harman Soho.

As the name gives away, these have an on-ear design instead of the over-ear design of most of Bose’s other offerings. The trade-off is that the On-Ear Wireless Headphones won’t be able to block out ambient noises as well, but some people might find them more comfortable. Plus they’re well cheaper than most other Bose wireless headphones. It should be noted that many reviewers, including Sound Guys, have praised the sound quality of these headphones.
The Bose QuietComfort 35 II is arguably still the most comfortable pair of noise-canceling headphones you can buy. Released in the summer of 2018, you can think of the QuietComfort 35 II as simplified, less sophisticated and more affordable version of the new Headphones 700. The lack the transparency mode, superior call quality, USB-C charging port and on-ear gesture controls, but they still boast really impressive noise-canceling skills. The also have the tradional foldable design — it folds more compactly — that many travelers really like.
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.
However, the Bose 700 earphones have a much slimmer profile when folded up, and they have a few updated elements, including more integration with digital assistants, touch controls, and sensors for Bose’s “augmented reality” apps. Bose has kept some of the best-loved features from its older models as well, such as adjustable levels of noise cancellation, a monitoring mode to let in sound from your environment, and an advertised 20-hour battery life. According to Bose, call quality is improved as well, though CR doesn’t test call quality in headphones.
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.
