FiiO M11S is the latest generation of premium Android digital audio players from the brand. FiiO has worked on the award-winning M11 bringing a new DAC design, a new powerful amplification design, and a new eight-core CPU. M11S comes with dual ES9038Q2M high-performance 32-Bit DAC chips that provide enormous performance upgrades compared to the previous generation. It’s a portable device with high capabilities, able to feed your IEMs with ease!!

New Sabre Dual DAC Design:-

M11S comes with a premium Dual DAC arrangement from ESS Sabre Technologies. The left and right channels have got their own independent ES9038Q2M high-efficiency DAC to better reproduce every last detail in your music. ES9038Q2M is a highly-capable DAC that delivers unmatched resolution and a crystal clear noise-free background!!

4th-Gen FPGA Clock Architecture:-

FiiO has developed 4th-generation FPGA architecture with phase-locked loop technology. It works together with two custom femtosecond crystal oscillators to provide a high-precision and low-jitter unified clock source for the entire audio chipset. This allows the M11S to deliver a pure, authentic high-resolution audio experience!!

Rich Sound With Audiophile-Grade Power Supply:-

Power plays an important role in any given audio/electrical device. FiiO has designed a new audiophile-grade clean power supply for the M11S. The amplifier and the opamp sections of the device get independently powered and are completely isolated from each other. This allows the M11S to produce a clean and powerful performance bringing our music to life!!

Powerful Amp Section:-

M11S brings a boost in the power output section all thanks to a newly developed amplification section. Under a 32Ω of impedance load, the M11S produces up to 670mW of clean power driving the most demanding of the IEMs with ease!!

6th-Gen Honeycomb Design:-

Designed with a new hexagonal structure, the M11S makes a striking first impression. It is amazing to hold, it conveys its energy with its edgy design. FiiO has featured their 6th generation Honeycomb design structure on the M11S, identical to the M11 Plus and the M17.

Blazing Fast Performance With Eight Core CPU and Open Android Architecture:-

M11S boasts lightning-fast performance with its eight-core Snapdragon 660 CPU and 3GB of RAM. The device has got 32 GB of internal storage and comes loaded with Android 10 OS. FiiO M11S has got Android SRC bypass, allowing full high-resolution lossless audio support across different applications including Apple Music, Tidal, Qobuz, etc.

Extended Battery Life:-

M11S houses a large 5300mAh battery pack. It supports Q4.0 and PD fast charging taking only 3 hours to fully charge. Once fully charged, M11S can provide a continuous music playback for up to 14 hours!!
