The Allen Ultrax 4148 Bionic Bluetooth earmuff combines active hearing protection with wireless audio connectivity for shooters and outdoor workers who need situational awareness without sacrificing comfort or safety. These are built for extended wear in high-noise environments—whether you're at the range, in the field, or managing noise on the job—with the convenience of Bluetooth pairing so you can stay connected to your phone or music without removing your hearing protection.
Built with a 1200mAh lithium battery that charges via USB-C, the Ultrax 4148 keeps working through long days in the field. The padded headband and soft ear cups are designed for comfort during extended sessions, while the rubberized exterior body gives you durability that holds up to real-world use. At NRR 22dB, these earmuffs deliver serious noise reduction and meet ANSI S3.19 safety standards—meaning you're getting certified hearing protection, not just audio gadgetry.
The Bluetooth 5.3 connectivity lets you pair seamlessly with devices, so you can take calls or stream audio while maintaining ear protection. The Studio Harmonics audio profile aims for clarity in both incoming audio and ambient sound amplification. The foldable design makes these easy to stash in a pack or bag when you're moving between locations, and the included USB-C charging cable means you're ready to go out of the box.

Yes. The Ultrax 4148 is ANSI S3.19 certified hearing protection with an NRR of 22dB, which provides serious noise reduction in high-sound-level environments. You're getting genuine safety standards, not just audio convenience.
The 1200mAh lithium battery provides hours of operation per charge. The exact runtime varies depending on usage (Bluetooth streaming, call time, and volume settings affect battery life). Charging via USB-C is quick, and a charging cable is included.
The product is designed as a Bluetooth earmuff with audio connectivity as a core feature. If you need hearing protection without wireless capability, these may not be the best fit—consider a traditional passive earmuff instead.
