Stay Fit, Stay Active, Stay Sony!

Since the beginning of time (or so it seems) Sony has been making just about everything a person could use in their household, at work, and everything in between. Not that Sony has been a "Me Too" brand, because that is actually the opposite of the Sony mentality. Sony has been a Pioneer, paving the road for many of those brands who are not brave enough to venture in to new territories, and exploring new ideas. Sony has also played a huge roll in trying to improve the way we experience our everyday lives. As many Americans have become educated to the effects of fast food consumption, and have learned to watch what they eat, Sony too has embraced ways to provide better experiences in living healthy. Sony's Fit and Active Sports products are not only the best in the industry, they are made for people like each and every one of us. They were engineered with specific materials to provide us with a better running experience, sweat resistant materials like these Sony MDR-AS41EX series earbuds. The Sony MDR-AS41EX/B provides users with all the same benefits of its predecessor the MDR-AS40EX (MDRAS40EX), like the comfortable flexible ear hangers, and the included portable carrying case, but there were some improvements made as well. Sony listened to feedback that they got on the MDR-AS40EX, and implemented the desires into the new model, the MDR-AS41EX/B. With three pairs of different sized ear hangers, and ear tips, users are sure to find the perfect fit. The sound ... well its hard to beat the MDR-AS40EX, but in true Sony fashion they delivered and "1 Upped" themselves. The MDRAS41EX series ear buds have an even broader frequency response tuned to deliver even deeper and more powerful bass levels. It doesn't get much better than this, so get with the program, and get even better sound performance from your earphones while your aspire to be even healthier.

Headphone Design

Headphone Type

Headphone type refers to the construction of the headphones.

Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.

Around the Neck means that the headphones wrap around the neck. This is also seen in active and sports headphones.

Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.

Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.

Around the Ear
Earpiece Design

This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.

In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.

Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

Specifically For
Some headphones can use an IR Transmitter in your vehicle, while some can be plugged into your media device and be used on the go or at home.

This is the lifestyle that the headphones are designed for. Each style has unique features that make it perfect for particular people.

Disc Jockeys (DJs) require a special type of headphone that can meet their professional needs. These headphones are durable, loud, and will often allow for one ear listening.

Fashion Enthusiast:
For those that want to make a fashion statement with their headphones. Not only are these headphones designed with great sound quality in mind, but also great looks!

Music Lover

General Features

Noise Reduction technology removes unwanted noise from a signal. Background or ambient noise can be removed to produce clearer speech and enhanced hearing. Typically these Active Noise Canceling (ANC) headphones are powered and use batteries to activate the noise canceling technology. Also referred to as Noise Reduction or Noise Cancellation.
Headphone Connection
This is how the headphones connect to the audio source.

Corded means that the headphones use a cord to transfer the audio signal.

Wireless means that the audio signal is transmitted wirelessly to the headphones.

1/4" Stereo Jack Adapter
Some headphones will come with a 1/4" stereo jack adapter to connect the usual 3.5mm jack to a 1/4" stereo plug.

1/4" Stereo jack is a larger audio jack that select electronics have.

Volume Adjustment
Volume Adjustment means that the headphone (independent of the source) can adjust the playback volume. Many headphones and ear buds have in-line volume control, which allows adjusting the audible volume from a switch on the headphones cord. Other headphones have a volume knob on the headphone can.
Built-In Microphone
This means that the headphones or earbuds have a built-in microphone. This can be a microphone on the cord, built into the headphone, or even a boom microphone. These mics can be used for music devices like iPods, for Smartphones to make and receive calls, or for gaming purposes.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
9 - 23000 Hz
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
100 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
9 mm
Driver Type
The physical design of the driver in the headphones.
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
16 ohms

Good, but not great.

February 7, 2014

These are decent earbuds, but nothing that is going to blow you away. The cord comes in two sections, the short main piece and a long extension which I like since I put my mp3 player and phone in my shorts pocket when I am working out. Has different buds for sizing as well as arms for around your ears, though I found the one already attached to be the best. The case is cool, but who uses them? Overall the sound is decent, I used them on an international flight to watch movies and they had good overall sound, but using them for music which I play loud, they were just like most any other earbuds on the market.

Great Earbuds

September 24, 2013

I have never seen these before, I hadn't seen them on Sony's site, but they are great! I had the Sony MDR-AS40EX for about a year. They were Perfect! I really have no complaints about that one. But I guess they don't make it anymore, and the people trying to sell the few that are left are really killing the price. I got mine for $35 and now they are trying to sell for $45-$60. too much. they were great and all, but again the reason I HAD to buy another pair is they broke. Granted, it was my fault when they phone fell off the bench at the gym it separated in the left ear and wouldn't work anymore. I don't want to spend $60 on something I might very well do the same thing to. At any rate, these must be the new model, they sure do look like the old ones. But I think the mids and bass is a little bit clearer on these. There just seems to be more of a presence on the bottom end with these AS41EX's. They feel a little bit stronger at the ear tip too where my old ones broke. Either that, or the old ones were like this and just wore in over the year or so I used them. I also do like the all black look more than the silver and black on the AS40EX. They fit really nice, comfortable, great for the gym or if your going for a little jog. Definitely recommend these!
