A guy used AirPods Max for 2 years.

He pressed play. He pressed pause. He toggled noise cancellation on planes. He answered calls.

That was it. 4 features. On a $549 device with 30+.

His coworker, a sound engineer at a recording studio, borrowed them for 10 minutes at lunch and handed them back with a look.

"You've never opened Settings once, have you? Apple built 9 features into these that change how you hear music, take calls, focus at work, navigate conversations, and protect your hearing. They're buried 3 menus deep and never mentioned in any ad. You've been wearing a $549 pair of headphones and using them like a $30 pair from the airport."

He spent 12 minutes in Settings that evening.

His music sounded different. His calls got clearer. He stopped removing his headphones every time someone talked to him. He hasn't touched a competing pair since.

Here's every feature his coworker showed him 🧵
First what the AirPods Max actually are underneath the play button.

Apple didn't build expensive headphones. They built a spatial audio computer that sits on your head. Inside the ear cups are 9 microphones, the H2 chip, a gyroscope, an accelerometer, and a processing engine powerful enough to analyze your environment 200 times per second and adjust sound in real time.

Most owners use none of this. They pair the headphones, press play, toggle noise cancellation when it gets loud, and assume that's everything. The other 26 features sit behind an iPhone Settings screen that the average owner visits once during the initial pairing and never opens again.

The sound engineer knew this because he'd tested $2,000 studio headphones for a living. He said the AirPods Max were the most capable consumer headphones he'd ever held. And the most underused. Because Apple buries the features that justify the $549 price tag behind menus most buyers never find.

Here are the 9 features he turned on.
Feature 1: He scanned his ears and turned on Personalized Spatial Audio.

This was the first thing he did. He opened Settings on the iPhone, tapped the AirPods Max at the top of the screen, scrolled to Personalized Spatial Audio, and tapped "Personalize Spatial Audio."

The iPhone's TrueDepth camera scanned both ears. It took 30 seconds. The phone built a 3D model of his ear shape and head geometry. From that moment on, every sound the AirPods Max played was tuned specifically to how his ears receive audio.

Without this scan, Spatial Audio uses a generic profile an averaged approximation of how most people hear. With it, the sound field matches his exact anatomy. Instruments separate. The soundstage widens. Vocals lock into position in front of him instead of floating somewhere vaguely inside his skull.

He said it sounded like someone had removed a thin blanket he didn't know was there. The music was the same. The headphones were the same. The profile changed everything.

He'd owned them for 2 years and never knew his AirPods Max were playing a generic version of every song.

Warren Buffett called him a superinvestor

Wall Street barely knows his name

He beat the market for nearly 50 consecutive years from a single room with no computer, no team, and no MBA

This is the story of Walter Schloss, the greatest investor nobody talks about
🧵 A thread Image
Walter Schloss did not go to college

At 18, in 1934, he got a job as a runner on Wall Street The Great Depression was still fresh Most people wanted nothing to do with stocks

Schloss was fascinated

He started taking night classes taught by a professor named Benjamin Graham One of his classmates was Gus Levy — the future chairman of Goldman Sachs

But Schloss wasn't chasing prestige He just wanted to understand how to find value

That quiet obsession would carry him for the next 70 years
After studying under Graham, Schloss went to work directly for him at the Graham-Newman Partnership

There he shared an office with a young analyst named Warren Buffett

In 1955 Buffett left to start his own fund Schloss left too — with $100,000 from a small group of investors

He rented a single room inside the offices of Tweedy Browne in New York No secretary No research team No Bloomberg terminal Just him, his son Edwin who joined in 1973, and the Value Line Investment Survey

That was his entire operation for nearly five decades

1/ Russian warbloggers are wondering how it was possible for Ukraine to destroy the Russian border patrol ship Izumrud while it was at anchor. The vessel was reportedly hit by two Ukrainian Sargan-3000 uncrewed surface vessels (USVs). ⬇️
2/ The attack is said to have caused several "200 and 300" (deaths and injuries). The big question, as 'Informant' comments, is "How the unmanned hull craft reached the ship at its berth."
3/ 'Evil Sailor' has "some very unpleasant questions for the border guards:

1. Why was the ship stationed in one place for so long when it was necessary to constantly change its base?

2. Why was the ship stationed in a completely unprotected area?

WARNING⚠️
Andy Burnham is running to be Prime Minister on the strength of the Manchester Model.
Before the country decides, it should know what that model did with £600 million of public money in its own backyard.
GMCA's housing loan fund lent around £600 million to a single private developer, Daren Whitaker of Renaker, to build the skyscrapers that have redrawn Manchester's skyline.
A tribunal found GMCA failed to obtain a statement of assets and liabilities from Whitaker before lending.
🧵
x.com/EuropeanPowell…Image
A meeting between a senior GMCA officer and Whitaker at which loan terms appear to have been agreed produced no minutes or notes.
Court papers allege Renaker presented high profit figures to GMCA when seeking loans, and low profit figures to Manchester City Council when seeking affordable homes exemptions.
The outcomes from £600 million of public money:
11,000 homes built.
Fewer than 503 classed as affordable.
Under five percent.
Almost all the money went to central Manchester, serving the relatively affluent and offshore investors who bought apartments as buy-to-let vehicles.

Same old England. On first viewing I thought Tuchel’s subs were disastrous. On second viewing, the retreat happened beforehand, a consequence of Argentina pushing on & England being exhausted. The three defensive subs did make sense. Analysis here…⬇️
nytimes.com/athletic/74485…
First sub: England had ended up in a back five/six beforehand (see below) after Argentina used four up top. Gonzalez on down the left completely changed the game. If you’re going to end up with Rogers/Gordon as an uncomfortable wing-back, you may as well play a proper back five. Image
Second/third subs: James injured. Burn on & Konsa across: a bit primitive, but OK. Rice was done. England’s problem had been on the near side with Messi and De Paul's crossing (below). O’Reilly - who played midfield for two months last season - was a decent choice for the left. Image

I entered $CERT at around 85 cents. It ran up to 2.40 C$, currently at 1.71 which means a mcap of 162 musd. After Q2 they likely have over 40 musd in the treasury. The debt side of the company is a bit complicated, key point is that a lot is the NPV of a stream which as I understand it practically means that Cerrado gets a couple of 100 usd lower gold price. Further there is some Argentinian debt the company chooses to keep rather than to pay it down. Finally a small bond. Key point is that the company balance sheet is rapidly improving and better than it looks imo.
At 4000 usd the company throws off about 25 musd from the Argentinian mine pre tax. The company does pay tax but companies rarely pay the nominal tax. One of the reasons is that the company that currently has a 2.5y minelife is drilling 50-60k meters to improve that situation. Early next year we are likely to have at least 5y minelife due to drilling and acquisitions imo. That will be a gamechanger in how the market values Cerrado. The company is also indicating that we by then can get a mineplan that increases the quarterly production from perhaps 15 to 20k ounces (gold equivalent).

The by-product is silver and pls note that the company lists its AISC after deducting silver but lists the annual production incl those silver ounces. The goal is to get to 100k ounces gold eq in two years. If we assume that as 90k ounces of gold and the silver keeping the AISC at 1500 usd (income from silver deducted from production costs) that would be an AISC margin 2500 x 90k ounces or a mine cashflow of 225musd. At 5000 usd, 315musd
Will all this play out? I simply look at some kind of risk reward and come to the conclusion that the risk of them not at least keeping current production, which is 100 musd cashflow vs a 163 musd mcap is is low imo but the chance of them moving their Argentinian mine to higher production from the underground and the latest heap leach acquisition seems quite good and if you end up with this asset doing cashflow 200-300 musd, well then we are likely up 5-10x the coming 2 years. A double the coming 12 months from here seems like a good chance to me. cerradogold.com/news-media/new…

national economy – said last week that a pickup in orders had yet to lift their bottom lines."

Or, as a friend who owns a medium-sized manufacturing business in China puts it: "Why is it so hard to find the happy people you'd expect to find in an economy growing at 5%?"

Analysts often say that China's soaring exports and its widening trade surplus are the bright spots for the economy, but it's not as simple as that. These are brights spots in the sense that they contribute to economic activity and allow China to keep production growing.

🧵Russian assault troops breached Kozacha Lopan, but they couldn't assemble. The drones made massing impossible. Putin built an army for a war where quantity equaled control. That battlefield no longer exists. 1/🇷🇺🇺🇦🧵
2/ The front is an absolute kill zone. Russian logistics have deteriorated to using FPV drones to drop tiny supply parcels to stranded men. Ukraine’s answer? Heavy ground robots armed with Browning M2 machine guns.
3/ To sustain this obsolete strategy, Russia is hallucinating soldiers through paperwork. Conscripts get three hours of driving practice instead of 72, pass a corrupt exam, and are immediately fed into infantry meat grinders.
