Four months ago, FiiO released the Bluetooth amplifier BTA10 for Audio-Technica ATH-M50x series headphones and soon won the favor of the market. At the same time, we received the requirements from customers for their different model of headphones. Here today, we are glad to announce that the additional version for Audio-Technica ATH-MSR7 series is available now. The two versions BTA10 (both for Audio-Technica ATH-M50x and ATH-MSR7) use the Qualcomm QCC3005 Bluetooth chip, with support for the latest Bluetooth 5.0 protocol as well as SBC/AAC/aptX/aptX LL audio codecs. Moreover, the BTA10 was specifically tuned to pair with the ATH-M50x and ATH-MSR7 series. With the BTA10, the ATH-M50x's sound becomes more monitor-like and gains more detail.Similarly, when the BTA10 is paired with the ATH-MSR7 the headphone reproduces more details with a more natural sound, for a better experience than even with the wired headphone cable. If you are in the mind to get one either for your ATH-M50x or ATH-MSR7, check with our local sales agent at: Click here for its availability or kindly buy it at our Aliexpress store if it's not available in your local market at: Click here Best Regards FiiO Electronics Technology Co., Ltd.
