My source for this is a comment from a thread called " what mic(s) does Kanye use" by the gearslutz user "PettyCash".

Everyone has at least 1 U87 so that's automatic. C800G, ELA M251.... mics that are probably too expensive for you to consider.

In this Mix with the Masters Webinar, Finnea's updates us with Billies new microphone chain. A Telefunken 251 into a Rupert Neve Designs 5211 2-Channel Microphone Preamplifier. Timestamp 9:35

At 2:18 you can see it the first time, but it is visible in numerous b roll shots throughout the video.

Ariana posted a video of her recording “Positions” on the studio with a Telefunken ELA M 251 E.

In this YouTube excerpt or any footage of Spike Lee's 'Bad' Movie showing the actual Behind The Scenes Studio Sessions of the Bad Album especially here with Michael Jackson & Stevie Wonder collaborating & recording keep-able vocals on "Just Good Friends" recorded in 1987 - Stevie Wonder can be seen here Singing into one of Bruce Swedien's Telefunken ELA M 251 E Microphones

Michael Jackson frequently used the Telefunken ELA M 251 E microphone for lead vocals, including on "We Are the World" and "Another Part of Me." In the "Bad Sessions" footage, Bruce Swedien's vintage Telefunken 251 E is shown, highlighting its use by various artists, including Stevie Wonder and Jackson himself.

Rosé (Blackpink) used the Telefunken ELA M 251 E microphone on a stand with a pop filter to record the hit "APT" with Bruno Mars. This is confirmed by a YouTube video from Berry🍒 B@ngpink stan, which shows Rosé recording the intro for "APT" on November 7, 2023.

Used on "Closer", as stated by producer DJ Swivel in this February 2017 Sound on Sound interview.

I recorded Halsey’s vocals at Westlake Studios, in Production Suite 1, using a Telefunken ELA M251E, going into a Neve 1073 mic pre and a Tube Tech CL1-B compressor, which is a classic female vocal chain.

In this YouTube Video at 0:31, you can see a 251E

Used for Sinatra's Swingin' Session!!!, as is visible in the album artwork (which is a photo of one of the album's sessions) and this photo. Despite the front of the microphone (which can be used to tell the 251 and 250 apart, let alone the E and non-E versions) not being visible, testimony to the microphone being a 251 E is given in this October 20, 2015 Recording.org forum post by user DonnyThompson.

I've actually had the fortune to have used an original early 60's ELA-M 251 E ... Once.

I was called in as a hired-gun engineer to work a recording session at a studio in Youngstown, Ohio a few years ago, ( Peppermint Recording - they'd been around for YEARS... I don't know if it's even there anymore, but when I was there it was like I was walking back into 1975 - yellow shag carpet, bean bag chairs, day-glo posters and all - LOL - it had definitely seen better days, though) and the owner of the studio had two ELAM's, both 251-E's.

When I asked him how he got them, he told me that he had purchased them in the mid 70's from Capitol Records Recording Studios in L.A. - for next to nothing - he mentioned paying something ridiculous, like $800 for BOTH. ( So...how come I can't ever run across incredible deals like that??? ).

With one of the mics, the mic itself worked fine, but the PS was fried, but the other one he had was fully operational with both the mic and the PS.

The owner had a picture hanging in his control room of an early 1960's Frank Sinatra singing into an ELA-M. ( He told me that he had been told by one of the older engineers at Capitol that the mic in the photo was one of the ones he purchased... although there's no actual way to prove that...but I suppose it's possible).

In This YouTube Video, Dolly and the Orchestra can be seen with Telefunken ELA M 251E's

The Telefunken ELA M 251 E can be seen at 1:31 into the video.
