7mm High-end Driver OWR-0745T-32 From OLE WOLFF:an excellent Choice for Active Noise Cancellation and True Wireless Applications
Excellent choice for Active Noise Cancellation (ANC) and True Wireless (TWS) applications
This Ø7mm dynamic driver for high-end earphones is designed with a focus on very high performance in earphones with ANC (Active Noise Cancellation), and TWS (True Wireless Stereo) and can also provide very good bass performance in leaky designs.
The OWR-0745T-32 features:
Excellent for Active Noise Cancellation (ANC)
Ideal for high-end True Wireless (TWS) earphones
High leak tolerance (great bass in leaky designs)
On par with (and better than) the driver used in the acclaimed Sony WF-1000MX3 earphone
BEATING SOME OF THE BEST
Comparison with the driver used in the excellent Sony WF-1000MX3 earphone
The Sony WF-1000MX3 is by many considered the industry leading earphone with both excellent ANC and overall sound quality.
In order to compare the OWR-0745T-32 with the Sony driver we carefully disassembled the WF-1000MX3 earphone and measured the Sony driver while still mounted in the nozzle part (black part to the right on the picture below) but without any air volume behind the driver. Next we replaced the Sony driver with the OWR-0745T-32 and ran the same test procedure under the exact same test conditions.
The excellent Sony WF-1000MX3 earphone (left) is considered the industry-leading consumer ANC earphone. The OLE WOLFF OWR-0745T-32 driver (middle) was tested using the nozzle part (right) from the earphone housing to make a fair 1:1 comparison between the drivers.
Lower distortion and better bass than the Sony WF-1000MX3 driver
The OWR-0745T-32 takes advantage of its extremely compliant Deep Drawn Diaphragm (Ole Wolff patent pending) which ensures low THD and excellent bass performance, as evident on the plots below. (hover picture to enlarge).
THE OWR-0745T-32 DRIVER
Utilizing the Drawn Diaphragm technique
The diaphragm design used in the driver takes advantage of Ole Wolffs Deep Drawn Diaphragm technology, which assures a maximum piston area and thereby the highest power efficiency to size ratio. High efficiency equals longer battery life which is key in ANC and True Wireless applications.
ACOUSTIC PERFORMANCE
High SPL and low THD: Ideal for Active Noise Cancellation
Low distortion at high diaphragm excursions is one of the key parameters for obtaining good ANC performance. OWR-0745T-32 can generate the very high sound pressure levels necessary in ANC applications with a minimum of distortion.
The driver generates very little distortion even at 10mW@133dBSPL in 2cc. (Hover the picture to enlarge).
