How Can I Stop Losing and Breaking My Headphones?
I'm terrible with headphones. I always wind up either breaking them after a few months of regular use, or I'll lose them entirely and never find them again. The cables snap, the plastic around the ears crack, or one of the ears will stop working. I think I'm cursed, and don't want to invest in a nice pair because I'm scared I'll break them! How can I stop?
Sincerely,
Headphone Wrecker
Dear Headphone Wrecker,
I used to be like you, always buying super-cheap headphones and earbuds because you knew you'd inevitably lose them. That's not a huge problem if you buy good cheap headphones, like our favorites, the $10 Monoprice 8320s, or the sub-$50 Koss PortaPros, one of your favorite headphones. Still, if you want better quality from your music, you're going to spend more, and even a $10 investment should last you as long as possible. Here are some ways to protect your headphones, keep them in good condition, and stop losing them on the commute home.
Learn to Coil Your Headphone Cables So They Don't Break
I used to go through earbuds pretty frequently too. Every few months, one of the ears would stop working or start crackling and work sporadically. I figured out pretty quickly that I had been routinely damaging the audio cable or the connection to the driver inside the headphones, so even if the outside looked fine, it wasn't working properly. Once I learned how to coil my headphone cables properly, that all stopped pretty quickly.
We have more than a few methods to coil your headphone cables without losing your mind (along with video so you can see how it's done) and without damaging your cables in the process. Part of it depends on you, though. Remember: the tighter you coil them, the more chance they have of breaking, so don't go overboard. My issue was that I caught myself wrapping them too tightly around my phone or my media player, and then letting the earbuds or headphones dangle, putting undue stress on the connection between the driver and the cable. Sound familiar? Don't worry, it's easy to fix, and once you stop coiling them that way, you'll instantly get more life from your headphones.
Reinforce Your Headphones with Sugru or Heat-Shrink Tubing
We've shown you how to repair earbuds with Sugru before, and it works like a charm. While you're at it, a little Sugru can also help you customize the fit on your earbuds so they're more comfortable to wear. If you prefer heat-shrink tubing, we have a guide for that, too.
Get Headphones with Removable Cables, or Hack Your Own
Store Your Headphones Properly
This should go without saying, but if you're still tossing your headphones at the bottom of your bag or coiling up your earbuds and shoving them in a side pocket, you can do better. Get a headphone case for your earbuds or your full-size headphones (they're available in all shapes and sizes at Amazon) and keep them in there. A good case will protect your investment, even if you have cheap headphones, and will also make sure you don't lose them?assuming you make it a habit of putting your headphones in their case when you're finished using them.
Similarly, you can kill two birds with one stone with a simple binder clip. Not only can you use the binder clip to attach your headphones to your shirt, bag, or pocket, but you can also use it to properly wrap your cables for easy storage.
Stop Buying Disposable Headphones
Hopefully these tips will help you buy better headphones or repair the ones you have. I know what it's like to spend $15-$20 repeatedly every couple of months on what you hope are headphones that will last a long time, only to be disappointed when they start acting up after regular use. You're not cursed, we promise!
Good luck,

Watch Jessie Ware Perform In A Flower Shop For Yours Truly
We?ve seen quite a few of our favorite females singing in odd places in the past couple months ? there was Sky Ferreira on a boat and Solange in the back of a cab ? and now comes another Idolator favorite,?Jessie Ware. The British singer linked up with?Yours Truly?in San Francisco for stripped-down performance?of her cover of ?What You Won?t Do For Love? in a flower shop.
Accompanied by an acoustic guitar, Ware?impressed us once again?with the sneaky power of her vocals. Since they were in a flower shop (or maybe that?s why they were in a flower shop?), Ware talked about past loves ? namely, that she often found herself in the friend zone with all her good-looking male friends, a victim of unrequited love. Ware said bittersweet songs are her favorite, so you can see why she covered this one on her EP?If You?re Never Gonna Move.

'Sequester' standoff need not be win-lose
Americans, not just politicians, are torn by so many choices in the budget standoff, now called the 'sequester.' One way for President Obama and Congress to avoid the consequences of sequestration is to adopt the concept of 'settling,' as put forth by one political theorist.
Arizona Gov. Jan Brewer speaks to a reporter before a meeting of the National Governors Association Feb. 23. Washington's budget stalemate could seriously undermine the US economy, the exasperated governors said.

EnlargeAmericans identify with people who are strivers. It is a trait anchored in ?the pursuit of happiness.? But personal striving can often lead to public strife. Take the ?sequester? and its March 1 deadline for Congress to avoid big budget cuts.

The sequestration battle is a prime example of a government failure to sort out the conflicting demands on the public purse from so many strivers. A new Pew survey, for instance, finds Americans can?t agree on what to cut in federal spending ? health, military, education, etc. How then can President Obama and the 535 voting members of Congress ever compromise?
But the excessive demands of strivers don?t usually have the same effect on local government. How is it that most cities, towns, and counties are able to settle their differences and balance their budgets? Why this difference between the federal and the local?
One answer lies in that word ? settle.
In a recent book entitled ?Settling,? political theorist Robert E. Goodin explores when and how we should settle in order to free ourselves to better discern and focus on our strivings. He suggests we ?prune our decision tree? as a way to achieve reconciliation and to strive better.
At the local level, voters and their representatives are less boggled by complexity and more familiar with issues. Local officials aren?t as paralyzed by choices, as many consumers are in a food store when they face a hundred brands of breakfast cereal.
Mr. Goodin, an American and philosophy professor at the University of Essex, in England, seeks to elevate settling to a virtue, in part to reduce the fear of making a wrong choice in a complex world.
Settling, he says, is not in opposition to striving but necessary for it. It is not resignation or agreeing to an unwanted prospect. It is a let-it-be-for-now ideal ? with an emphasis on the ?for now.? It is humility based on patience and an improved perception of goals.
Excessive striving can lead to disaster, such as that of the doomed Antarctic expedition of explorer Robert Scott. But striving tempered by settling can lead to victory, such as Mao Zedong?s Long March (a tactical and temporary retreat).
Modern technologies, such as the Internet and smart phones, have enhanced the tendency for restless desire and extreme behavior ? or ?chasing rabbits,? as Goodin says. People are in need of a more coherent life with fixed constants that can create trust and allow agreement, he says.
Mr. Obama, he points out, has evolved from the candidate of 2008 with lofty rhetoric and many goals to the president of 2013 who has learned to focus on fewer goals and knows when to settle.
The same sort of settling must happen with members of Congress if Washington is to end its fiscal crisis. Too many of them, both Democrats and Republican, are striving to an extreme, often to please narrow interests, and too often in many directions at once. The closest that the nation came recently to a fiscal settling was the 2010 deficit reduction panel known as Simpson-Bowles, a bipartisan letting-go of set positions ? for now.
Settling is not making a habit of making do ? of being only ?good enough? ? forever. It is interim deprivation on purpose. It is a prudent art that can be used in public debates about government. It is a value to be cherished and perfected as much as striving.
In order to strive, Goodin advises, we must settle. That common quality need not be an uncommon virtue.

The team implemented the 'phase estimation algorithm' a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It lies at the heart of quantum computing and is a key sub-routine of many other important quantum algorithms, such as Shor's factoring algorithm and quantum simulations.
Dr Xiao-Qi Zhou, who led the project, said: "Before our experiment, there had been several demonstrations of quantum algorithms, however, none of them implemented the quantum algorithm without knowing the answer in advance. This is because in the previous demonstrations the quantum circuits were simplified to make it more experimentally feasible. However, this simplification of circuits required knowledge of the answer in advance. Unlike previous demonstrations, we built a full quantum circuit to implement the phase estimation algorithm without any simplification. We don't need to know the answer in advance and it is the first time the answer is truly calculated by a quantum circuit with a quantum algorithm."
Professor Jeremy O'Brien, director of the Centre for Quantum Photonics at the University of Bristol said: "Implementing a full quantum algorithm without knowing the answer in advance is an important step towards practical quantum computing. It paves the way for important applications, including quantum simulations and quantum metrology in the near term, and factoring in the long term."
The research is published in Nature Photonics.

Texas A Texas A&m cotton bowl Fiscal cliff deal kathy griffin jadeveon clowney orange bowl
Investors face yet another Washington deadline
U.S. investors face another Washington-imposed deadline on government spending cuts next week, but it's not generating the same level of fear as two months ago when the "fiscal cliff" loomed large.
Investors in sectors most likely to be affected by the cuts, like defense, seem untroubled that the budget talks could send stocks tumbling.
Talks on the U.S. budget crisis began again this week leading up to the March 1 deadline for the so-called sequestration when $85 billion in automatic federal spending cuts are scheduled to take effect.
"It's at this point a political hot button in Washington but a very low level investor concern," said Fred Dickson, chief market strategist at D.A. Davidson & Co. in Lake Oswego, Oregon. The fight pits President Barack Obama and fellow Democrats against congressional Republicans.
Stocks rallied in early January after a compromise temporarily avoided the fiscal cliff, and the Standard & Poor's 500 index has risen 6.3 percent since the start of the year.
But the benchmark index lost steam this week, posting its first week of losses since the start of the year. Minutes on Wednesday from the last Federal Reserve meeting, which suggested the central bank may slow or stop its stimulus policy sooner than expected, provided the catalyst.
National elections in Italy on Sunday and Monday could also add to investor concern. Most investors expect a government headed by Pier Luigi Bersani to win and continue with reforms to tackle Italy's debt problems. However, a resurgence by former leader Silvio Berlusconi has raised doubts.
"Europe has been in the last six months less of a topic for the stock market, but the problems haven't gone away. This may bring back investor attention to that," said Kim Forrest, senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.
The spending cuts, if they go ahead, could hit the defense industry particularly hard.
Yet in the options market, bulls were targeting gains in Lockheed Martin Corp , the Pentagon's biggest supplier.
Calls on the stock far outpaced puts, suggesting that many investors anticipate the stock to move higher. Overall options volume on the stock was 2.8 times the daily average with 17,000 calls and 3,360 puts traded, according to options analytics firm Trade Alert.
"The upside call buying in Lockheed solidifies the idea that option investors are not pricing in a lot of downside risk in most defense stocks from the likely impact of sequestration," said Jared Woodard, a founder of research and advisory firm condoroptions.com in Forest, Virginia.
The stock ended up 0.6 percent at $88.12 on Friday.
If lawmakers fail to reach an agreement on reducing the U.S. budget deficit in the next few days, a sequester would include significant cuts in defense spending. Companies such as General Dynamics Corp and Smith & Wesson Holding Corp could be affected.
General Dynamics Corp shares rose 1.2 percent to $67.32 and Smith & Wesson added 4.6 percent to $9.18 on Friday.
The latest data on fourth-quarter U.S. gross domestic product is expected on Thursday, and some analysts predict an upward revision following trade data that showed America's deficit shrank in December to its narrowest in nearly three years.
U.S. GDP unexpectedly contracted in the fourth quarter, according to an earlier government estimate, but analysts said there was no reason for panic, given that consumer spending and business investment picked up.
Investors will be looking for any hints of changes in the Fed's policy of monetary easing when Fed Chairman Ben Bernake speaks before congressional committees on Tuesday and Wednesday.
Shares of Apple will be watched closely next week when the company's annual stockholders' meeting is held.
On Friday, a U.S. judge handed outspoken hedge fund manager David Einhorn a victory in his battle with the iPhone maker, blocking the company from moving forward with a shareholder vote on a controversial proposal to limit the company's ability to issue preferred stock.
