The best true-wireless in-ear headphones
Once again, Bowers & Wilkins uses a combination of high-quality materials. The round plastic body coects the driver's arm with the chic metallic exterior. The manufacturer also adopts the shape, but the Pi7 S2 offer better wearing comfort than their predecessors. The plugs sit firmly in the ears and exert a slight but not unpleasant pressure. Music fans have a choice of three different rubber tips. This is sufficient in many cases, but three sizes are a bit meagre, given the price.
Functions
The free "Music Bowers & Wilkins" app (for iOS and Android) is also mediocre. Although the smartphone application offers a little more than its predecessor, it lacks essential functions such as an equaliser for adjusting the sound. At least the noise-cancelling can be switched, and the transparency mode can be adjusted in steps. The app also provides information about the current charge level of the in-ears. Users of Tidal, Deezer, Soundcloud or NTS can coect their account to the app and start their favourite tracks without changing programmes. However, streaming giant Spotify is left out, and Apple Music or Amazon Music Unlimited users are left out in the cold. The earphone controls work well, and commands such as "Play" or "Skip track forward" are implemented well. Unfortunately, the volume can only be controlled via smartphone.
Bass
Bowers & Wilkins remains at a high level in terms of sound, and the Pi7 S2 sound as good as its predecessors. The present bass colours the sound character, as do the clean voices and incredible detail. The finely resolved music reproduction is pleasing, but tracks with subtle lows have an advantage.
Fitting i
The Pi7 S2 are equipped with microphones that pick up ambient noise. Simultaneously, the in-ears send a counter-sound to the music fan's ears. The wave superposition creates silence in the ear. This is similarly effective to the famous Apple AirPods Pro (2nd generation). In addition, in "Auto" mode, the noise suppression strength adjusts to the ambient volume. If there is a lot of noise, the B&W shield the wearer more effectively. This works well, and deep, sonorous noises like traioise do not interfere with musical taste. Even voices are effectively quieter, but they do come through now and then. If you want to pay attention to your surroundings, you can switch to the "ambient pass-through" (transparency mode). In this mode, users can pay attention to train aouncements, for example, as sounds can reach the ears unhindered if desired.
Equipment
There is no surprise in the battery life. At four hours and 46 minutes, the in-ears are just behind their predecessors. At least they are quickly full again, and a ten-minute rest in the charging case is enough for another four hours - excellent. The transport box has remained the same shape and size. Its 6x6x3 centimetres (HxWxD) is a bit bulky, but it has a special extra hidden inside: There is a Bluetooth transmitter in the box. It can be plugged into the headphone socket of a stereo system, for example, using the cable supplied. The audio signal from the hi-fi tower then reaches the in-ears via radio. The first version already had this practical function.
