Audio

It is Smart & Adaptable

Qualcomm aptX Adaptive

aptX Adaptive is an extremely efficient audio codec that automatically adjusts its bitrate in real-time, based on your usage and surrounding, like a crowded RF environment that is extremely common in today's digitized era.

It is closer to you than you know, like a bedroom with smartphone and smartwatch chargers, LED lights, and even hair dryers-when put together, the RF emitted by these devices will inevitably disrupt your connection quality.

With aptX Adaptive, connectivity issues are reduced to a minimum and you will always get the most optimized Bluetooth audio regardless of where you are and what you are playing. No user control or configuration required.

1 Your audio devices (i.e., Bluetooth headphones or speakers) need to support aptX Adaptive as well to enjoy the benefits of the codec.

What does aptX Adaptive do?

“It promises high resolution, uninterrupted audio that simply works, delivering a premium and robust solution.” - aptX.com

It's stable and reliable

Creative BT-W4 offers high-definition 24-bit audio at 48 kHz when streaming with aptX Adaptive. Along with Bluetooth 5.2, enjoy stable, high-quality, and reliable connection for your music, movies, and games.

It also automatically chooses the best available audio codec supported by your device, so you are guaranteed the best possible Bluetooth audio every single time.

It makes life simpler

Good news for the gadget geeks who own a whole fleet of Bluetooth audio devices! Forget the hassle and repetitive steps of disconnecting, searching, and pairing whenever you want to switch between your Bluetooth headphones and speakers.

Example: When you are reconnecting to previously paired devices

HFP Mode2

Switch from whatever you're listening to and pick up a short phone call instantly! Double press on the Bluetooth button to enter HFP mode, and use voice chat with the built-in microphone on your Bluetooth headset. Best for: PC and Mac, where the likelihood of audio pickup, for example, keyboard typing noises from the desktop, is high.

2 In HFP mode, the Creative BT-W4 allows you to use your wireless headset for voice chat, but premium A2DP Bluetooth codecs (aptX Adaptive, aptX, and SBC) will not be available.

Analog Microphone

Plug in the bundled analog microphone to your device via its 3.5 mm jack, and use it for voice chat while streaming audio wirelessly to your Bluetooth headphones. Lead, assist, or hard-carry your team to victory as Creative BT-W4 lets you communicate your strategy across in real-time.

Best for: Gaming consoles such as PS5 and PS4, where there isn't noise interference from keyboard taps and desktop movements.

Design

It's really, really small

Weighing about the same as three potato chips, the Creative BT-W4 is a mammoth in functionality but an absolute
lightweight in size. Its small build is comparable to a beer bottle cap, so it won't get in your way. All you need is a
free USB port to get it plugged in and running, while occupying negligible space on your desk.
