5 Things to Know When Choosing Perfect Headphones

5 Things to Know When Choosing Perfect Headphones

Headphones are available in a lot of different styles, brands and prices, which make it hard to find a right pair for you.

Are you aware of the celebrity-endorsed headphones trend? If so, then just be clear that when you open up the spec sheet, things are still confusing. In this article, we’ll discuss in detail the key headphone specifications and why they matter.

1. In-ear Headphones

The first and the foremost are the in-ear (canal) headphones. These ear pieces fit directly into your ear canal, also called as in-ear monitors. In-ear headphones offer two significant benefits to the wearer. First of all, they deliver excellent sound quality because it’s nearer to the ear drum. Secondly, it fills out way into the ear; that’s why it’s quite useful in sealing out external noise.

These headphones are available in different sized tips, so you can choose accordingly. If you want to attain the best performance, it’s important to get the right size.

2. On-ear Headphones

These headphones are also called supra-aural headphones, which sits on the top of the ear. Similar to the in-ear headphones, they also send the sound straight into the ear canal, but can’t block out outside noises. Moreover, people sitting next to you can hear what you’re listening to.

A lot of people find on-ear headphones more comfortable as they don’t trap heat on your ears, unlike over-ear headphones. But clamping might be an issue for some folks out there as they may complain of headphones squeezing too tightly and irritating their ears. Try to find a pair that sits well.

When it comes to sound quality, on-ear headphones offers you a good balance of high sound quality along with a decent level of portability.

3. Over-ear Headphones

Over-ear headphones are also called circumaural headphones as they encase the entire ear. They are large; that’s why also contain a large driver with enhances bass performance and louder volume. When it comes to positioning, it is placed far away from the ear and produces a more spacious sound, which resembles the sound of the speakers.

4. What Are Drivers?

The driver of a pair of headphones is believed to be a critical component. It can convert an electrical signal to sound pressure. In other words, you can say that it produces sound.

Drivers are of different types, but all of them primarily contains magnets, a diaphragm and voice coils.

The diaphragm vibrates due to these components and then these vibrations produces sound waves, which we interpret as sounds.

On a spec sheet of a pair of headphones, the driver is indicated by the diameter of the diaphragm is mentioned in mm (millimeters). Most of the time, the driver size is directly proportional to the sound quality, particularly when it comes to bass performance. Take over-ear headphones for example. A 40mm driver proves to be a good size for sound quality.

On the other hand, in-ear headphones are smaller in size, so can’t fit a larger driver easily. That’s why some technical experts use the dual-driver approach, in which your headphones have two drivers; one for bass and the other for mid and high frequencies.

5. Paying Attention to Sensitivity and Sound Pressure Level

When it comes to the SPL (sound pressure level) or sensitivity; both terms are related. It indicates the loudness of your headphones. You can explain the sensitivity as something that measures how competently an electrical signal is converted into an acoustic signal. Similarly, sound pressure is how you measure the sensitivity.

Some of the top Bluetooth headsets lie within the range of 80-120 dB SPL/mW. To provide some context; a shouting voice is around 105 dB, regular city traffic 80 dB and the plane take off 135 dB.

25 Excel shortcuts to increase your productivity

Here are 25 great Excel shortcuts you should learn and use for work or studying to make your job faster and simpler. Try to use them all and you will realize you were totally blind before while working in Excel:

1. Format whatever object fast with Ctrl+1

If you select any object in Excel – a cell, a chart, a chart axis, a drawing object – then press Ctrl+1, and you will get the Properties dialog for the certain object. This shortcut offers a very quick and easy way to format whatever object you’re working with.

2. Use range names with Ctrol+G or F5 key

If you use range names (which we strongly recommend to do) and you want to choose the range with a specific name references, press either Ctrl+G or the F5 key, which launches the GoTo dialog.

If the name is simple, you can click on it in a list in that dialog. But if it’s at all unusual, Excel won’t list it; so you will need to type in the name. Then press OK.

3. Use a range name in a formula with =sum( and F3

Suppose you want to use a range name in a formula. For example, you want to sum the Sales range. Enter…

=sum(

…and then press F3.

When you do so, Excel launches the Paste Name dialog. Just choose “Sales” from the list, press the OK button in the dialog, then enter the SUM function’s closing “)” to complete the formula.

4. Launch Function Arguments dialog easily with Ctrl+A

Suppose you want to check the help topic for a worksheet function. For example, you want to read about the MATCH function. In a cell, type…

=match(

…and then press Ctrl+A, or click the Insert Function (“fx“) button to the left of the formula bar.

When you do so, Excel displays the Function Arguments dialog, which might offer all the help you need.

But if you still want to see the complete help topic, click the blue “Help on this function” hyperlink in the lower-left corner of the dialog. This technique works with all documented Excel functions.

5. Copy stuff down the column without scrolling with Ctrl+D

If you added a formula in a new column on the right of a huge dataset, and you want to copy that formula down without scrolling, do these steps:

  • go to the right to the column that has data (the column to the left of the new column with the formula);
  • press Ctrl+Down – to get to bottom;
  • move one cell to the right (with arrow key naturally);
  • press Ctrl+Shift+Up to select the new column, at the top of which is the formula you just created;
  • press Ctrl+D to fill down the formula.

6. Quick access to any function with Alt+

By customizing the quick access toolbar, you can create simple shortcuts to commands that you would otherwise have to find in the Ribbon tabs, or macros you have created yourself.

The keyboard shortcut is simply selecting Alt+ (the number of the command you wish to select).

For example, if you have customized your quick access toolbar to have Calc Sheet, Save, Open. To calculate sheet you would hit Alt+1, for save Alt+2, and for open Alt+3.

A lot of people are unaware of this useful function, and it’s a great time saver.

7. Format cells with Ctrl+1

When you need to format cells, use Ctrl+1. Most people know this as the shortcut for the Format Cells dialog, but you can also use it to format almost anything in Excel, without a care about the state of the ribbon. Try this amazing and simple shortcut!

8. Choose visible cells with Alt+

When you need to choose visible cells only – use Alt+. This is the trick to copy only what you see. It is a priceless shortcut when you’re manually hiding rows and columns in the table.

9. Use filtering

Filtering – it is a powerful way to slice, dice, and sort through a huge table of information.

It’s amazingly effective when you’re participating in a meeting to discuss something like a sales forecast, and everyone is looking in real-time at your spreadsheet projected on a screen (or on their monitors).

To some people, you will be seen as the God of Spreadsheets, and this is not a joke!

10. Insert or delete column/row easily with the Ctrl key

Some people waste a lot of time even for simple operations, for example, when they need to insert/delete columns and rows in Excel.

Use this shortcut to insert: with an entire row or column selected, use Ctrl+Shift ++.

To delete: with an entire row or column selected, use Ctrl + –.

11. See formula results with F9

If you want to check formula results within multiple formulas, highlight the formula and select F9 to see formula result.

Don’t forget to undo before exiting the formula.

12. Use ALT+Enter for more text within a cell

If you want to add a second line of text within a cell, use ALT+Enter.

13. Use EDATE to move a date on by a full calendar month:

Here’s how to use EDATE:

=EDATE(15/01/16,+1) = 15/02/2016 (15th Feb 2016)

=EDATE (15/01/2016,-2) = 15/11/2015 (15th Nov 2016)

14. Use EOMONTH to move a date onto the end of the month:

Here’s how to use EMONTH:

=EOMONTH(15/01/2016,0) = 31/01/2016 (31st Jan 2106)

=EOMONTH (15/01/2016,-2) = 30/11/2015 (30th Nov 2015)

15. Remove spaces with TRIM

TRIM is a useful function known by few people. It removes any spaces at the beginning of a value. This is useful if you are pulling in values from somewhere else.

16. Repeat commands with F4 or Ctrl+Y

In many cases, you may need to repeat your last action. Use F4 or Ctrl+Y; you can repeat many commands like applying the same borders, format, or insert a worksheet again.

17. Quick access to cells with the Ctrl key and Shift key

When you need to go to the first or last cell of a worksheet, no matter where you are, use Ctrl+Home, Ctrl+End combinations.

And here is a pleasant bonus for you: add the Shift key to select everything on the way!

18. Use Ctrl+ to create a timestamp

If you need a date stamp and/or a timestamp in your document, there is no need to type a date and time! Use shortcuts Ctrl+ ; (date) Ctrl+Shift+ : (time). It works like a magic and helps to save your time and nerves.

19. Use autosum shortcut for sum function anywhere

Autosum shortcut – use Alt =. It is a “magic” shortcut of Excel to automatically insert a sum function.

You can use this shortcut to sum rows, columns, or even an entire table in one step without wasting your time.

20. Use data validation

This is an amazing but underutilized tool in Excel, which can be used for a variety of things:

  • Create dependent drop-down lists;
  • Create drop-down lists;
  • Protect/restrict data input of specific cells (without the need for VBA macros).

21. Use conditional formatting

It can be used for various purposes such as color format or cell format of cells, rows or columns based on dependent cell values or formats.

22. Use formula auditing

This is a great tool to analyze and trace precedent or dependent cells, check errors and evaluate formulas.

The “Watch Window” is a feature to keep a snapshot of an area of the spreadsheet, and then move to another area of the workbook – particularly valuable if you’re managing large spreadsheets or don’t have a second screen.

23. Use Scenario Manager to generate summary outputs of a spreadsheet

Scenario Manager (under “What-if Analysis”) enables users to generate high-level, summary outputs of a spreadsheet – without the need to replicate the entire workbook.

It will present multiple scenarios of a spreadsheet in a succinct, high-level summary worksheet.

24. Use INDIRECT to set up large tables

INDIRECT makes it easy to set up tables which reference larger tables without a lot of referencing work or cutting and pasting; especially for dynamic spreadsheets.

25. Use OFFSET for complicated calculations or formulas

OFFSET can be useful for things like calculating YTD numbers or creating formulas that take data in rows and using in columns.

The bottom line

As you can see, when you have a boring or tedious job to do, the best way to do it fast is not looking for a way how to avoid it, but searching for the shortest variant to do it!

That is why we suggest keeping in mind these Excel shortcuts that will help you to save a lot of time and nerves.

If it seems hard for you to remember all them, you can print out the list of shortcuts and keep it on your worktable. Use it to search for some help when you need it, and over time, you’ll remember all shortcuts easily.
