### 2/5 — DB4S

*2026-05-21*

Hab die nad c658 als Vorstufe. Kann dadurch leider den subwoofer nicht im stereomodus betreiben. Weil das augangsignal des nad zu schwach ist . Wäre nicht wenn man irgendwo die pegelempfindlichkeit und das Level oder Volumen einstellen könnte .

### 1/5 — Apps so bad I returned the sub

*2026-03-07, version 1.3.8*

I’ve been a bowers and Wilkins customer for 40 years now. In replacing my much loved PV1 I thought the logical upgrade was a DB3D. The problem is this app stalls so much and the subs so dependent on the app that I couldn’t ever get a reliable connection with my 805D4s. What a horrible, relationship ending experience this app has been. REL for me sadly but life’s too short to be laboring over bad tech in a hifi setup.

### 1/5 — 请问怎么调整低音炮电平？

*2026-01-03*

原来在主页还有电平的调节项，把自动开启和关闭分开后就直接取消电平调节功能了！那你加上物理旋钮啊！

### 1/5 — 用脚做软件

*2025-12-22*

连上时间长就算了，关键是还能断 重新连也不行 属实牛逼

### 4/5 — iPhone 15 Pro | DB4S

*2025-11-09*

wird leider, warum auch immer, keine Kalibrierung zur Raumkorrektur unterstützt! Es wird leider immer wieder ein Massfehler angezeigt! Mit meinem alten IPhone 7 funktioniert es einwandfrei!

### 3/5 — Test-Modus fehlt

*2025-01-16*

Bei der Überlegung einen B&W DB-Sub zu kaufen würde es sehr helfen die APP in einem “Test-Mode“ anschauen zu können ohne einen Subwoofer zur Verfügung zu haben. Hier wäre auch gleich zu sehen, ob mein B&W Lautsprecher mit auf der Liste steht.

### 5/5 — Très bien!

*2024-03-23, version 1.3.7*

Fonctionnement impeccable! Merci!

### 2/5 — Es fehlen viele Funktionen für einen komfortablen Betrieb

*2023-10-17*

Ich betreibe zwei DB4S zur Unterstützung meiner B&W 804 D3.
Was mir fehlt sind:

1) Presets auf der Startseite der App
2) synchrone Steuerung von 2 Subwoofern
3) An/Ausschalter in der App

Es ist ein fast abendfüllendes Unterfangen, die 2 Subs z.B. Von "Musik" auf " Film" umzustellen, oder auch andere Einstellungen auszuprobieren oder anzupassen. Warum kann man die beiden Subs nicht synchron steuern?

Warum kann ich nicht bestimmte Einstellungen festlegen und als Presets auf der Startseite der App speichern? 

Außerdem fehlt ein On/Off-Schalter in der App! Die Subs schalten verzögert ein, was nervt. Und die kürzeste Abschaltzeit sind 20 min. Bei den zwei eingebauten 1000W Verstärkern könnte man so unnötigen Stromverbrauch vermeiden.

Die App verschenkt viel Potential, denn die Einstellungsmöglichkeiten sind super! Aber sie werden nicht genutzt, da viel zu umständlich zu erreichen!

### 4/5 — Update bitte!

*2023-05-23*

Tolle App, die alles bietet einen Subwoofer einzustellen und das vom Sitzplatz aus. Aber bitte ein Update, um die Lautstärke weiter reduzieren als nur -10dB! Subwoofer beim einmessen viel zu laut.

### 5/5 — A5

*2022-10-30*

Hi I can’t connect my speaker A5 to Bluetooth I’m using iPhone XS any idea?

**Developer response:** Hi the windsurfer, 

Many thanks for your review and enquiry.

The first model within our legacy Airplay speakers offering Bluetooth hardware was the Zeppelin Wireless; all prior models, including your A7, were Airplay only, for wireless use.

To setup connection of your speaker, please contact us directly, through support@bowerswilkins.com.

Many thanks, Bowers & Wilkins.
