IFI Zen Blue vs Audioengine B1: Bluetooth Range
The IFI Zen Blue and Audioengine B1 receivers both use Bluetooth 5.0 technology, which has a maximum range of 800 feet. However, in a real environment, the range is typically between 80 and 100 feet.
The Audioengine B1 receiver slightly outperforms the IFI Zen Blue. It has an extended WIFI range which enhances its coverage area. It is less likely to drop your connection as you walk between rooms.
IFI Zen Blue vs Audioengine B1 – Audio Quality
The quality of the audio depends largely on the quality of the connection and audio source. As both receivers use the latest Bluetooth technology, you do not need to worry about a reduction in quality due to signal loss.
Both receivers also support aptX HD, aptX, and AAC encoding for high-definition audio. You can stream CD-quality audio at 24 bits / 192 kbps.
The main difference between the two receivers comes from the digital-to-analog converter (DAC). The IFI Zen Blue uses the Qualcomm QCC5100 DAC. The Audioengine B1 is equipped with an AKM4396 DAC. The AKM4396 is made by the world’s largest DAC manufacturer. It was created as a high-performance DAC for sampling DVD audio at 24 bits while the QCC5100 was made for wireless earbuds.
Compared to the Qualcomm QCC5100, the AKM4396 chip offers better audio. It was made to reduce high-frequency noise on high-end audio systems, which should help it deliver a better audio experience.
IFI Zen Blue vs Audioengine B1: Outputs
Most Bluetooth receivers include a pair of RCA stereo outputs. You can connect the left and right audio directly to your audio receiver or powered speakers.
The IFI Zen Blue and Audioengine B1 also have a digital optical output. If your receiver or speakers have an optical cable input, using this connection delivers superior audio. Compared to analog RCA, optical connections provide better protection against interference and signal loss.
The IFI Zen Blue also has a coaxial digital output and a mini stereo jack. These extra outputs may make it easier to connect the receiver to certain devices.
For example, you may have a speaker system that only has a mini stereo jack or a coaxial connection instead of a digital optical connection. However, almost every analog receiver or powered speaker includes RCA analog inputs. You should have no problem connecting either Bluetooth receiver to your existing sound system.
Should You Choose the IFI Zen Blue or Audioengine B1?
The IFI Zen Blue and the Audioengine B1 are quality Bluetooth receivers with many of the same features. Both receivers use Bluetooth 5.0 technology and support HD audio.

The IFI Zen Blue offers a couple of advantages, including a slightly cheaper price tag and extra outputs. Yet, the Audioengine B1 is likely to deliver better audio.
The B1 Bluetooth receiver has audiophile-grade connectors. Whether you use analog or digital outputs, the metal connectors help protect against interference that may degrade the quality of the signal.
Maintaining the Bluetooth connection as you walk around the house is also easier with the Audioengine B1. The device has a range of up to 100 feet and stays connected through walls.
The Audioengine B1 is also smaller and easier to position. While both options are compact, the B1 is less than 1-inch tall and just 3.5 inches wide.
In the end, you can enjoy CD-quality audio streaming with the Audioengine B1 or the IFI Zen Blue. Yet, the Audioengine B1 is a step above the competition thanks to its superior DAC.
