Bowers & Wilkins P9 Signature Review
When Bowers & Wilkins celebrated half a century of successful business we rightly expect that such an anniversary is worthily celebrated. This time, the company decided to introduce a superior pair of headphones: Bowers & Wilkins P9 Signature over-ear headphones that will surely satisfy the audiophiles, but also customers who look for top quality, selected materials and a peculiarity of the product. Why headphones? The company that built its reputation for the production of speakers actively turned on in the flood of headphones that have been splashed the audio scene for the last few years.
Almost everyone who has an interest in the audio domain has joined the race, and the market is really in a short time segment filled with the most diverse models in all price ranges. Of course, the environment of mobile music players, cell phones, and all cheaper and cheaper storage space for similar devices played a role in popularizing the headphones, but one part of the merit certainly carries the trends. Watching the streets of our cities makes it easy to conclude that there were never more music lovers on the move. Great news, if such a habit is a result of the need for music and less fashion detail.

But time will show how much such an observation is based, and in the meantime, every high-fidelity sound reproduction fan can enjoy a huge offer and a variety of models. Just a few days ago, I had a pleasant occasion to talk to a large number of audiophiles on the Zagreb CanJam space this year at the AV Hotel Fair in the Sheraton Zagreb Hotel. It’s almost incredible how many visitors expressed the desire to listen to music from their cell phones and with the most expensive headphones models. It was not just curiosity. It’s about a whole new kind of music fan. Much has changed in the last few years and a completely new category of interest appears. An excellent trend with the hope that it will last. But let’s go back to the subject itself. B & W P9 Signature are headphones that are designed and manufactured to the highest standards of the company. Engineers of the company embarked on a project aware of the customer’s expectations and decided to make the product virtually from the idea on paper. Thanks to the resources available to them, and above all to their product research and development center, they had the freedom to realize their thoughts. They decided on a combination of top quality materials, proven ideas and several innovations. Aluminum, composites, and leather were used as basic materials.
For the Bowers & Wilkins P9 Signature headphones completely new loudspeaker units (drivers) have been developed that, with powerful magnets and innovative suspension, enable dynamic and precise motion of the membrane, and are most valued for the sound that the headphones deliver. There is also a solid aluminum construction that provides a stable and optimized base for the construction, designed to isolate the vibration of a single channel and thus ensure the autonomy of each headphone unit from reciprocal vibration. The company thinks it’s that part of the design is deserved for the purity and openness of the headphones sound. But that’s not all. Headphone units are set at a 15-degree angle concerning the ear to try to outpace the space. The finish is in line with the design and is made of “Saffiano” leather produced in Italy. So let’s go to the test in which we have 4cm wide bandwidths with “CCAW” coil and acoustic coat, specially designed memory foam earpads that are magnetically attached to the structure and the exterior that imposes.

Conclusion
The B & W P9 Signature has been tested with several preamps with tube and transistor configurations and with several portable players and cell phones. Space does not allow the inclusion of every detail, but the highest value of the headphones is their consistency and the characteristic that their sound is recognizable in every configuration. Bowers & Wilkins has marked its half-century in the way it expects from companies of such a level. We wish them a happy birthday, of course. However, P9 Signature is a bit of an exclusive product with its price and status. This is confirmed by both construction and sound.
