The Oppo HA-2 SE internal Sabre DAC accepts just about any type of high-resolution file formats up to 32/384 kHz as well as DSD formats too. The flexible HA-2 SE unit can accept a digital signal input connection from an Apple iPhone, iPad, iPod (even the iPod Classic!), or any Android-based smartphone, tablet, PC or laptop.
It also has the ability to connect via line-output to any analog device, making the HA2-SE truly a versatile amp/DAC combo useful to a broad swath of music-loving listener either jamming portably on the fly or enjoying some quality headphone time at home or office.
The dimensions of the Oppo HA 2 SE amp are a perfect match for any smartphone. The unit's internal rechargeable lithium-ion battery gets a respectable 7 hours of run-time using the digital input and an extended 13 hours using the analog line input. So it should make those transcontinental flights or work days in the cubicle go by much faster without needing a recharge.
There is a 'High/Low' gain adjustment to allow dovetailed use with even the most sensitive in-ear headphones up to demanding full size high-impedance reference cans or planar magnetic headphones. A bass boost switch is a nice touch if you find the need for a little more booty bump in the lower frequencies. There's also an indicator button to check the battery level at a glance; the LED doubles as a status light during recharging.
If you are concerned about new Apple iOS products like the iPhone 7 dropping the headphone jack, worry yourself no more. The Oppo HA-2SE headphone amp / DAC unit is an easy no fuss, no muss solution since it will connect directly to the proprietary Apple Lightning port.
In the end, don't hesitate picking up the portable Oppo HA-2 SE headphone amplifer / DAC if you're looking to score the maximum acoustic performance from any player device and your favorite pair of great headphones.
