The beyerdynamic is the more sensible fit for a desk or studio where you can stay connected by cable. SGPRO is built around a transmitter and bodypack receiver for moving around a performance space.

For calls, it’s best suited to someone who is happy with a wired headphone and a stationary setup. It is not a Bluetooth headset, and the listed details do not specify a microphone, so I wouldn’t choose it when a built-in calling mic or wireless movement is essential. Nor is it a complete wireless monitor system for performers who need a separate transmitter and bodypack.
SGPRO is a wireless in-ear monitor system, not simply a pair of Bluetooth earbuds. Its setup combines a metal transmitter with a bodypack receiver and monitor earphones, using UHF transmission. The stated coverage reaches up to 100 meters, and enhanced antenna diversity is intended to help maintain reception. Those details make it relevant to performers who need to hear a monitor signal while moving around a stage or event space.
The transmitter supports three audio inputs, including XLR and 1/4-inch connections, and the system offers 85 adjustable frequencies. One transmitter can connect to multiple receivers, which can help when a group needs to listen to a shared monitor feed. The bodypack receiver is battery-powered, with a stated average battery life of six hours; the transmitter is corded electric.
That makes SGPRO a better match for bands, studios, and live events than for ordinary calls. Its wireless operation does not make it a general-purpose Bluetooth call product: the listed wireless technology is UHF, and the system is organized around a transmitter, receiver, and audio inputs. If you want simple earbuds for a phone conversation—or sleep headphones for calls—this is the wrong shape of solution. It also asks more of your setup than a wired headphone does.
Side-by-Side: Which Should You Choose?
• Best for a wired call setup → beyerdynamic s DT 770. It is the more natural choice if you sit at a desk and prefer an over-ear headphone connected by cable. Its listed details do not include a microphone, so check that your call setup has a separate mic if needed.
• Best for stage or event monitoring → SGPRO. The transmitter-and-bodypack design, UHF link, and stated coverage of up to 100 meters serve a different purpose from ordinary listening headphones.
• Best for connecting varied audio gear → SGPRO. Three transmitter inputs, including XLR and 1/4-inch connections, make it more adaptable to compatible equipment than a headphone with a 3.5 mm jack.
• Best for a straightforward desk setup → beyerdynamic s DT 770. One wired headphone is simpler to place into a stationary listening routine than a separate transmitter and bodypack system.
• Best for sharing one monitor feed across receivers → SGPRO. The system is described as allowing one transmitter to connect to multiple receivers, which is useful for group monitoring.
• Best for a replaceable-parts design → beyerdynamic s DT 770. Its cable, ear cushions, and headband can be replaced, giving owners specific serviceable parts.
• Best for a gaming headset for calls → neither is a clear match. The beyerdynamic is wired but has no microphone listed; SGPRO is a UHF monitoring system, not a conventional gaming headset. Confirm the microphone and connection needs of your setup before choosing either.
The phrase “usb c charging bluetooth earbuds for calls” points to a third category, not either product here. The beyerdynamic is wired, while SGPRO uses UHF and a battery-powered bodypack. Neither data sheet describes USB-C charging or Bluetooth earbuds, so I wouldn’t buy either on that basis.
I’d choose the beyerdynamic s DT 770 for a stationary listening setup and, between these two, for calls—provided a separate microphone is covered. I prefer its simpler wired format, comfortable over-ear design, detachable cable, and replaceable parts for everyday desk use. SGPRO is the more capable choice when the actual job is wireless monitoring for performers. For calls, my pick is beyerdynamic, not because it is a call headset, but because its form and setup are the closer fit.
No. It is a wired over-ear headphone with a 3.5 mm jack and detachable cable.
It is designed as a UHF in-ear monitor system with a transmitter, bodypack receiver, and monitor earphones. The listed details do not identify it as a phone-call headset or specify Bluetooth calling, so I would not choose it for ordinary mobile calls.
The beyerdynamic is the simpler choice if you want a wired headphone for a desk or studio. SGPRO involves a transmitter and bodypack receiver, with audio inputs intended for equipment such as compatible XLR or 1/4-inch sources.
SGPRO is the clear fit for that specific need. It uses UHF transmission and lists coverage up to 100 meters, whereas the beyerdynamic is a wired headphone intended for recording and monitoring.
