New Desk HiFi Audio Setup (Audiophile)

HiFi Desk Audio Setup Audiophile - Hack Your Productivity

(Infographic picture at bottom of post)

When I really need to focus on getting work done, I have to turn the music in my headphones up really loud.  My headphones are Sennheiser HD600, which have an impedance of 300 ohms.  This means they are a bit harder to drive than other ‘normal’ headphones.

When I listen straight out of the headphone jack from my MacBook Pro – even at max volume – they don’t get as loud as they are capable of getting.  This is where my headphone amp comes in handy.

So now, I want a way to get digital audio out of my MacBook Pro, then send a fresh analog signal into the O2 headphone amp, to be amplified into my headphones.  However, I also want to be able to easily switch between headphones and desk stereo speakers.

The downside with using optical out from my MacBook is that it’s a fixed level, so I can’t adjust the volume with my keyboard knob any more.  So now I’ll have to use the knob on the desk speakers and the knob on my headphone amplifier – but that’s a small price to pay for high quality – very amplified sound.

Here’s an infographic to display how my setup will function when I get the remaining parts.

Lapel Mic for iPhone 7 Plus (Lightning to 3.5mm)

iPhone Lapel Mic Adapter Setup - Productivity Hacks

I’ve been doing more editing on my iPhone lately, so naturally I wanted a way to get higher quality audio during videos than the iPhone’s built-in microphone allows.  I thought it might also be handy to record podcasts directly on my iPhone, when I didn’t feel like sitting at my work desk.

TRS TRRS ExplanationI have used a Sony ECMCS3 Lapel mic for a couple videos I’ve recently uploaded to YouTube, and I really like the way it sounds.  I want to use this mic on with my iPhone, but this mic has a ‘TRS’ (Tip, Ring, Sleeve) input; whereas the iPhone needs to accept a ‘TRRS’ (Tip, Ring, Ring, Sleeve) input.

This is because the iPhone wants to have access to 1) left audio, 2) right audio, 3) microphone, and 4) ground.

How I Hooked it all Up

I plugged my lapel mic into the TRS to TRRS adapter, and then plugged that into the Apple Lightning to 3.5mm dongle.  I then opened up the Voice Memos app to test it out.

Phantom Power

It didn’t work. *Frown face*  From what I’ve read on multiple Amazon product reviews and other websites, the audio recorder that I normally use with my lapel mic (the Olympus LS-10) must be providing phantom power to the Sony mic, and the iPhone is not providing that power.

There are other options for adding microphones to the iPhone via lightning, but I really wanted to continue using this lapel mic that I already enjoy.  Sadly, it appears that won’t be possible.

Perhaps if I get a splitter for headphone and microphone inputs, and have a pair of headphones plugged in at the same time, the iPhone will see the proper load and use the microphone.  I’ll try that next, but for now I’m upset that the adapter I already bought won’t do the trick.
