Today I’m going to writing about the Symphonized NRG MFI Earphones. These earphones feature an Apple MFI certified lightning connector. So, they’re ready to use in your iPhone without any adapters.

Bluetooth technology has developed rapidly in recent years and audio equipment has benefited hugely. But, sometimes having a cabled set of earphones has its advantages, such as not having to recharge them or signal loss and interruption.

The Symphonized NRG MFI Earphones are made from genuine Bubinga Wood, not only pretty looking but this wood ensures good acoustics. The angle of each earbud has been designed to fit tightly into your ears too, perfect for comfort and for banging tunes.

But are they any good? Sound quality? Time to test them out!

Packaging and Contents.

The Symphonized NRG MFI Earphones come in a small cardboard box which features product specifications. The outer box measures 9.5cm x 9.5cm x 4.0cm and weighs 100G.

Symphonized NRG MFI Earphones.

The Symphonized NRG MFI Earphones are made from wood (Bubinga Wood) and measure around 1.2M in length and weigh 15G.

You’ll also notice some fine Chrome detailing, and this also continues onto the end section where the drivers are located.

There’s also inline control too, this located on the right-hand side and is located around 15.0cm from your right ear.

This inline control has three control buttons, these are Plus (+), Minus (-) and a Multi-Function Button (Centre MFB Button). The Plus and Minus buttons only increase/decrease volume, you can’t control track selection. Which is a major shame!

The MFB centre button is your Pause/Play button and enables you to Answer/End phone calls as there is a built-in microphone located on the reverse of the in-line control area. Also pressing and holding the centre MFB will call upon Siri on your iPhone. If that’s your thing!

Lightning Port.

The end plug is a little different. Usually you’ll see a 3.5mm TRRS (Top Ring Ring Sleeve) input jack on standard earphones. But the Symphonized NRG MFI Earphones feature a certified Apple lighting connector, the same connector that you use to charge your phone. This plug ensures you can seamlessly plug and play on any iPhone that features a lightning port. And without the dreaded ‘This accessory may not be supported’ popup too.

The only downside to using the lightning port for audio is you’re not able to charge your phone at the same time. Unless you purchase a splitter adapter.

The advantage of these earphones seems to be an instant set of cabled earphones without having to use the 3.5mm/Lightning cable adapter.

Audio Quality.

Before you can judge a pair of earphones on sound quality you firstly need to ensure you’ve fitted the correct sized ear tips to suit your ears. Choosing the wrong type will cause sound leakage and prevent you from fully enjoying your music. Luckily Symphonized have you covered with a total of 6 pairs of tips, all different shaped and sized. You need to find a tip that fits snuggly in your ear canal without falling out and without hurting you. To change a tip pop off the old one, turn the new one inside out and slide it over the earphone. That’s it!

OK getting onto the audio, the sound is bloody fantastic, this is usual of other Symphonized audio products. I like the way bass is more prominent in their products, it suits my style of music.

Sound cancellation is exceptionally good too (When you choose the correct silicone tip), you become totally immersed in your music, with nice punchy bassy tones.

Noise isolation however is not as good, people around you are able to hear some audio leakage. So, you’ll annoy your fellow peers, but you’ll be so immersed in your music you’ll not give a flying funk.

To summarise the sound is brilliant.

I like the Symphonized NRG MFI Earphones. The sound is nice and punchy, the MFI lightning connector works well too. But, there’s still some room for improvement.

Firstly, I’d like to not only control volume but also track selection too. This i believe is a basic function of any pair of earphones.

Secondly, they get confused if you pause audio and keypad lock your iPhone, you’re not able to play from where you left off from by pressing the middle MFB button. You must start the track again from the beginning on your device itself. Which is rather irritating.

But the sound makes up for those two issues, if you like bassy tunes you’ll love these, they also look incredibly beautiful too.

If you want the Symphonized NRG MFI Earphones for yourself, they’re available for purchase only on Amazon. The RRP for this product is £31.99.
