With the TMA-2 MFG4, AIAIAI has released the first set of USB Type-C headphones that actually work well. It’s surprising howbad this category has beensince thePixel 2ditched the headphone jack — it’s been atrain wreck so far.
Who are the AIAIAI TMA-2 MFG4 for?
What is the AIAIAI TMA-2 MFG4?
In short, the AIAIAI TMA-2 MFG4 is the very first Made For Google set of on-ear USB Type-C headphones. They’re an amalgamation of interchangeable parts for the AIAIAI TMA-2 series, comprising of the standard headband, theS01 speaker units, theE01 earpads, and theC60 USB Type-C to 3.5mm cable. If you want to add or swap out parts for these headphones, you can do that without a second thought, as these are completely modular by design.
If you’re unsatisfied by any part of the headphones — or just a little rough with your peripherals — you’re able to repair or replace any component without losing the whole unit. That’s a pretty incredible value right there, considering most headphones are trashed when the band or cable breaks. This is especially good because the housings are made of inexpensive plastics, so they may not take many tumbles before giving up the ghost.
By offering an in-cable DAC, the headphones don’t need anything but a standardUSB Type-C portto plug into. Of course, this isn’t always a given on devices, so you may be in for a stupid surprise depending on your device — through no fault of the headphones. However, that digital audio processing is a treat if you use the headphones with a modern smartphone. There’s only a very small number of headphones that use the new USB Type-C standard, and none really qualify as “audiophile” cans.
The stock setup isn’t exactly to my tastes, as I’m not a fan of on-ear headphonesat all.However, these are decent for what they are. The cloth padding snaps into the ear cups, and can be removed for easy cleaning. Additionally the band provides a consistent (but not overpowering) clamping force to keep these things on your head. You may get uncomfortable after an hour and a half like I did, but like every set of on-ear headphones, that’ll vary from person to person. They’re a little on the heavy side compared to models like theJLab Rewind Wireless Retro.
How does the cable connect?
My biggest gripe with the AIAIAI TMA-2 is their 3.5mm connections. While I’m happy they’re there, I loathe the proprietary system of twisting and locking the connections into place preventing the use of generic components should something break. Being unable to connect cables to your headphones due to a tiny plastic thing breaking defeats the entire purpose of having a removable cable, so it’s more than a little frustrating.
How do the AIAIAI TMA-2 MFG4 sound?
On-ear headphones are popular because they’re usually pretty comfortable, but they come with their own drawbacks inherent to the design — namely, they don’tisolateall that well. While the AIAIAI TMA-2 MFG4 sound great when everything’s perfect, it’s not always possible to get that result. If you manage to get a perfect fit, the headphones sound pretty nice, with only a few foibles. No notes fall more than 10dB below others, which is surprisingly decent for any set of headphones. This allows you some latitude to equalize your tunes and hear mixes the way they were intended to sound.
I’m a fan of the flatter (all notes the same power) kinds of frequency response, but bassheads may want to try one of the other headphone modules AIAIAI offers for the TMA-2. The upside to a flat response is clarity. You can easily hear things you may have missed in the mixes of your songs — that’s a big plus if you’re a fan of older songs like I am. You’ll actually be able to hear the bass and lowest piano octaves in Barry White’sNever Never Gonna Give Ya Up.
Mids see an ever-so-slight emphasis over all other notes, but that’s really not a bad thing. It adds a little more punch to vocal features important to immersing yourself. Language will sound “off” or strange if you’re able to’t hear the initial impact of a plosive, for example. A response like the TMA-2’s lends itself well to vocal-heavy mixes, much like themother of the MP3:Tom’s Dinerby Suzanne Vega.
Should you buy the AIAIAI TMA-2 MFG4?
If you’re in a position where USB Type-C audio is preferable to Bluetooth, these are currently the headphones to get. They aren’t amazing, they cost $150, and they don’t offer any killer features. However, they work well — without an app — on both Android and Windows. That’s enough to be the top of the USB Type-C heap for 2018.
However, they aren’t better than other headphones at the same price. They absolutely have their audience, but forunder $100you can get some damn decent options. USB Type-C may yet provide a killer audio product, but the TMA-2 isn’t enough to justify thedeath of the headphone jack.
