Telefunken M80 is a beautifully designed yet sturdy microphone that produces a very clear sound when used on my vocals, so in that regard it's a welcome addition to my collection. With minimal EQing on my part, the clarity is closer to studio mics rather than your usual dynamic handhelds that tend to get a bit dull.
That said, the packaging looks quite cheap (like a budget karaoke mic or a toy you could win from a claw machine), and I wouldn't consider the sound to be noticeably better than the likes of sE Electronics V7 or Sennheiser e935/e945, which offer comparable quality for half the price or even less. If you're not looking to splurge, I would suggest checking out the less expensive alternatives first.
One fun thing about the M80 and M81 microphones is the variety of colors they're available in. Not just that, you can use the official Telefunken Custom Shop to choose the colors you want for the grille & body and get a custom mic made for you . So, if you're someone who likes to add memorable visual components to your performances, the option might be worth your attention.
