BlueParrott's B450-XT and B350-XT were built for calls in noisy, mobile work environments. In 2026, both are legacy models: BlueParrott's support pages mark them discontinued, while the brand has moved to newer Pro B450 and Pro B350 products. If you already own a B450-XT or B350-XT—or are considering remaining stock—the comparison and pairing guidance below still matters.
Quick answer: the B450-XT and B350-XT share a 96% microphone-noise-reduction claim, up to 24 hours of talk time, IP54 protection, multipoint for two simultaneous device connections, and a mono over-the-head design. The B450-XT is heavier but adds Bluetooth 5.0, USB-C charging, VoiceControl, and a 20 Hz–20 kHz speaker range; the B350-XT is much lighter and uses Bluetooth 4.0 with Micro-USB charging.
B450-XT and B350-XT Status in 2026
BlueParrott still hosts product and support information for both models, but its support pages mark the B450-XT and B350-XT as discontinued. Product pages may also show sold-out inventory depending on region.
If you are buying new rather than maintaining an existing headset, compare these legacy models with BlueParrott's current Pro line before paying a premium for old stock. Wantek's current trucker-headset guide also explains how the established B450-XT fits beside newer driver-focused options.

What the B450-XT Offers
The B450-XT is the larger of the two headsets. BlueParrott lists a padded headband, large cushioned earcup, customizable BlueParrott Button, large controls, VoiceControl for answering or rejecting calls, NFC, USB-C charging, Bluetooth 5.0, and IP54 dust/moisture protection.
Its microphone claim is about the sound sent to the person on the other end of the call: BlueParrott says the mic blocks 96% of background noise. That is different from active noise cancellation for the wearer's ear. The B450-XT's core value is outgoing call isolation in a mono work headset, not consumer-style listening ANC.
What the B350-XT Offers
The B350-XT keeps many of the same work-call fundamentals: a 96% microphone-noise-reduction claim, up to 24 hours of talk time, IP54 protection, the customizable BlueParrott Button, NFC, app support, and connection to two devices at the same time.
Its clearest physical advantage is weight. BlueParrott lists the B350-XT at 77 g, compared with 161 g for the B450-XT. The tradeoff is older Bluetooth 4.0 hardware, Micro-USB charging, and a narrower specified speaker frequency range.
Microphone Noise Reduction Is Not Listening ANC
Both models are frequently described as “noise-cancelling headsets,” but the important function here is the boom microphone's background-noise rejection. It is intended to help the caller hear your voice over road, engine, warehouse, or worksite noise.
Do not interpret the 96% figure as “96% quieter for the wearer.” BlueParrott attributes the figure to independent laboratory verification of its microphone noise cancellation. Listening-side ANC is a separate feature category.
Range and Multipoint
Both product pages list pairing with up to eight devices and simultaneous connection to two. That is useful if you move between a work phone and a second Bluetooth device without re-pairing each time.
BlueParrott historically advertised up to 300 ft / 100 m for the B450-XT, while current product pages describe range as phone-dependent. Treat any maximum range as a best-case specification; a vehicle body, walls, other radios, and the paired device can reduce real range.
How to Pair a BlueParrott B450-XT or B350-XT
BlueParrott's current support instructions use essentially the same button-pairing sequence for these models:
Power the headset off
Start with the headset turned off so the Multifunction button can enter pairing mode.
Hold the Multifunction button
Continue holding after you hear “Power on” until the LED alternates blue and red and the headset announces “Pair mode.” BlueParrott specifies about six seconds for the B450-XT.
Select the headset on your phone
Open the phone's Bluetooth menu and choose BlueParrott B450-XT or BlueParrott B350-XT from the available devices.
Use the PIN only if requested
BlueParrott's support instructions specify 0000 if the phone asks for a PIN.
If Pairing Does Not Work
- Make sure the headset is actually in pairing mode, with the alternating blue/red LED rather than simply powered on.
- Remove an old BlueParrott entry from the phone's Bluetooth list if the phone keeps trying to reconnect to a stale pairing.
- Temporarily disconnect the headset from another nearby device if multipoint behavior is confusing the setup.
- Use BlueParrott's model-specific support page before attempting a factory reset; reset button combinations can differ by hardware revision.
Which Legacy Model Makes More Sense?
For an existing owner, there is no reason to replace a working B350-XT merely because the B450-XT has a higher Bluetooth version. The B350-XT is much lighter and shares the same current 24-hour talk-time and 96% microphone-noise-reduction claims.
If choosing between remaining stock at similar prices, the B450-XT's USB-C charging, Bluetooth 5.0, VoiceControl, and broader speaker range are more modern conveniences. But because both models are discontinued, warranty, seller quality, battery age, and availability can matter more than small feature differences.
What If You Are Buying New in 2026?
BlueParrott introduced newer Pro B450 and Pro B350 models after these XT generations. If you need a new professional-driver headset, compare the current models rather than assuming a discounted legacy unit is automatically the better value.
More generally, a trucker headset should be chosen as a call tool: microphone noise rejection, mono situational awareness, talk time, controls, fit, charging, and phone compatibility should come before entertainment features.
Frequently Asked Questions
Are the BlueParrott B450-XT and B350-XT discontinued?
Yes. BlueParrott's current support pages label both models discontinued, although product information and support resources remain online and some sellers may still have inventory.
How long is the talk time?
BlueParrott lists up to 24 hours of talk time for both the B450-XT and B350-XT, with 500+ hours of standby time.
Can either headset connect to two devices?
Yes. Current specifications list up to eight paired devices and two simultaneously connected devices for both models.
Does the B450-XT have active noise cancellation for listening?
Its headline noise claim refers to the boom microphone reducing background noise sent to the caller. Do not treat that microphone specification as listening-side ANC.
