Bose IE2 EQ settings for Mac
Measured EQ correction for the Bose IE2, the specs that matter, and what changes when you use them with a Mac. Copy the settings and apply them in one click.
The short answer
- Turns the bass down by about 7 to 8 dB from 31 to 125 Hz.
- Lifts the mids around 1 to 2 kHz by about 3 dB.
- Adds about 6 dB around 4 to 8 kHz for detail.
- Raises the top treble at 16 kHz by about 11 dB.

Using the IE2 with a Mac
Codec: AAC. The IE2 support , and a Mac picks AAC, the better of the two. It carries the full 20 Hz to 20 kHz range at standard sample rates (44.1 or 48 kHz).
Calls sound worse than music. As soon as an app uses the earbuds' microphone (Zoom, FaceTime, a dictation shortcut), Bluetooth switches to hands-free mode, which has much lower audio quality. Pick your Mac's built-in microphone as the input to keep the IE2 in stereo music mode.
What the measurements show
This correction comes from AutoEQ, based on Harpo's measurements of the IE2. It shows how much to boost or cut at each frequency to bring the earbuds closer to AutoEQ's neutral target:
- Turns the bass down by about 7 to 8 dB from 31 to 125 Hz.
- Lifts the mids around 1 to 2 kHz by about 3 dB.
- Adds about 6 dB around 4 to 8 kHz for detail.
- Raises the top treble at 16 kHz by about 11 dB.
Fit, ear tips and your own ears all change what you hear, and neutral isn't everyone's favourite sound. Use this as a starting point, then adjust by ear.
Apply it in TuningMac (parametric EQ)
TuningMac's Advanced EQ imports this format directly. Copy the settings, then:
- Open TuningMac ▸ Settings ▸ Advanced EQ with your IE2 connected.
- Turn on Use Advanced EQ for IE2 (or whatever you've named them on your Mac).
- Choose More ▸ Paste from Clipboard.
TuningMac saves it for your IE2 and loads it whenever they connect.

Prefer simple sliders? The 10-band version
No Advanced EQ needed: AutoEQ also gives values for a standard 10-band equalizer, the same bands as TuningMac's main EQ. In the menu bar popover choose Custom, set each slider, and set the preamp to about −11.0 dB.
Values in dB, at 31 Hz to 16 kHz. The parametric version above is more precise.
Questions
Which codec do the Bose IE2 use on a Mac?+
AAC. The IE2 support , and a Mac picks AAC, the better of the two. It carries the full 20 Hz to 20 kHz range at standard sample rates.
What are the best EQ settings for the Bose IE2?+
AutoEQ's correction, based on Harpo's measurements, turns the bass down by about 7 dB, adds about 6 dB around 4 to 8 kHz, adds about 11 dB at 16 kHz, with a preamp of -6.6 dB. The exact values are on this page, ready to copy. Treat it as a neutral starting point and adjust to taste.
Why do my Bose IE2 sound bad on calls on a Mac?+
When an app uses the earbuds' microphone, Bluetooth switches from stereo music mode to a hands-free call mode with much lower audio quality. To keep music quality during calls, choose your Mac's built-in microphone as the input instead. TuningMac's Input list does this in one click, and its Device Info shows which mode you're in.
Should I turn off the EQ in Bose's app?+
For the most accurate result, yes. An equalizer set in Bose's app is applied inside the earbuds, so it also affects your Mac and would add to this correction. TuningMac's EQ only changes sound from your Mac, so it won't affect your phone.
