If you're ready to upgrade from the free headphones that came with your latest phone to a serious setting, you'll need to invest in high-quality hi-fi. The following mobile audio file tools are a great place to start.
Audiophiles is a famous exciting thrill ̵
Digital audio player: FiiO M7 ($ 200)
Your smartphone is a jacket of all business, and a master of none special if it's a newer model that's unclearly missing a headphone sport. If you are serious about quality sound during the run, you want to upgrade to a dedicated music device.
This mid-range model from mobile audio specialist FiiO offers a full touch screen for its Android operating system, something that is not a given for this price point, but unfortunately not for a phone – there is no Wi-Fi or mobile connection in this case. Instead, you get a dedicated, long-lasting music-enabled device that can handle lossless audio playback, with a powerful DAC (digital to audio converter) to get the most out of your headphones.
The player comes with only 2GB of storage, but you can add up to 512GB with a MicroSD card and also supports playback via USB-C-enabled audio devices and Bluetooth with Sony's upgraded LDAC high-quality wireless. Other features include a 20-hour battery life (40 hours standby) and built-in FM radio support. Oh, and it's loaded from the latest USB C cables – a nice extra. Note that this device does not have access to the Google Play store or its music apps selection, despite Android OS.
Portable Amplifier: TOPPING NX4 DSD ($ 160)
If you'd rather keep the phone for music but you want to maximize quality and the power of your advanced headphones, you want an amplifier. Portable amplifiers work with the same principles as their media center and desktop cousins, only with an internal battery, a pocket-sized size and a selection of ports selected for ongoing listening.
Connect your phone (or anything else) into the port, plug in the headphones or a speaker to the port and enjoy the glory of enhanced sound. Topping NX4 DSD supports audio quality up to 32 bits – probably much more than your phone can handle either a standard headphone cable or a digital USB connection.
There is also a smart design decision: The micro USB charging port and USB-C data port are separate so you can either connect and charge the amplifier via the phone or leave it separately to provide more battery life. The NX4 uses an all-aluminum body with a fantastic knurled dial for the main gain control. It stays for 24 hours in amplifier mode, but it is important if you also use it as a digital to audio converter. Considered, it contains some silicone tapes to cure it on the phone if you carry both in a pocket.
Bluetooth receiver: Earstudio ES100 ($ 100)
] Let's say you already have a good pair of headphones, but the sound you want to listen to on your phone or other device do not have a standard 3.5mm headphone jack. Get this little gadget and stream things over Bluetooth.
While Bluetooth is not usually associated with high quality audio, ES100 includes support for 24-bit playback, meeting, or beat the best smartphones. Its Bluetooth receiver chip supports Sonys LDAC and Qualcomms aptX and aptX HD wireless audio standards. Both regular and larger 2.5 mm jackets are available on board, as well as a microphone, so you can turn a few pairs of studio quality cans into a mobile headset. Impressively, it can also be controlled remotely via an Android or iOS app, allowing for extensive customization of equalizer controls and settings for the integrated DAC.
Earrings: Shure SE315 ($ 178)
Most headphones are cheap tickets designed to be cheap so you do not mind breaking or lose them. But the sealed earplugs in your earplugs also contribute to excellent noise reduction and high credibility, so it's possible to get an impressive sound quality if you're willing to invest in a good pair. Shure SE315 is certainly qualified.
With a 22Hz-18.5KHz range that blows most earplugs out of the water, the removable cable can be upgraded with USB-C, Apple Lightning or Bluetooth connectivity through Shure branded accessories. Kevlar reinforcement around the cab can be set to curve around the ear for a more comfortable and safe fit.
Headphones: Sennheiser HD 598 Cs
For those with both their bag and budget, a high quality pair of headphones which is not heard will be heard. For the mobile audio file without boundless handbags, we recommend the Sennheiser HD 598 Cs.
It's a closed design for private listening with passive shower shutdown, with a handy shorter cable that includes a built-in microphone for mobile calls. The headphones range is a massive 10Hz-28kHz, so you can hear every subtlety in your high-quality music. The folding design easily drops into the supplied bag, but you want a bag for when you are not using them. There are headphones out there with better specifications on paper, but for less than $ 200, these are great and make a great gift too.
