Product Details

Headphones Designed for Critical Listeners
AKG K240 headphones' comfortable, lightweight design and semi-open earcups are popular with studio performers, while their dead-accurate frequency response makes them an engineer favorite. The most recent K240 update adds XXL transducers for detailed lows and highs over a greater dynamic range, plus a fully detachable 10-foot cord for easy replacement.

Semi-Open-Back Design, Ideal For Vocalists
Have you ever seen a singer reach up to remove one headphone earcup? Headphones are a must when overdubbing vocals, but when you're used to hearing the acoustic sound of your voice in a room, it can be disorienting to hear only the tight, close-up sound of your voice on a microphone. So vocalists often take off one ear, missing out on half the stereo mix and increasing the odds of take-ruining feedback. That's why AKG K240 headphones have a semi-open-back design that allows some "room" in alongside your headphone mix as you perform. If you're singing, playing an acoustic instrument, or recording in the same room as your amp, these headphones allow you to hear more of the sound you're accustomed to -- even with both sides on. If your headphones feel a little too claustrophobic, you'll find semi-open K240 headphones less distracting than the closed-back variety.

XXL Transducers Deliver Accurate Sound
Inside cups that cover your entire ears, the K240 headphones have light, responsive low-impedance XXL transducers that deliver accurate, true-to-the-source reproduction of even very quiet signals. With AKG's patented Varimotion diaphragm, XXL transducers produce a flat, neutral frequency response from 15 to 25,000 Hz, revealing every nuance of your music. And because of the semi-open-back design, they provide less bleed and more acoustical isolation than typical high-end reference headphones, making them perfect for everything from tracking in the studio to casual listening to an MP3 player. The included adapter make K240 headphones compatible with standard 1/4" or 1/8" headphone jacks.

Get Comfortable: Self-Adjusting Headband
Designed to stand up to the daily use (and abuse) of a never-ending parade of studio musicians, K240s are lightweight with a springy headband that opens or closes wider for large heads and closes in for smaller ones automatically, without adjustment. A fully detachable, replaceable 10-foot cord means that if you've rolled over your headphone cable one too many times, there's no need to buy a whole new pair of K240s -- you can easily swap out the cable for a third of the price, should you ever need to. But as a studio commodity, K240 headphones are priced so everyone in the band can wear them. Where else can $100 buy such an essential critical-listening tool?

- Semi-open-back design combines the superior frequency response and "breathability" of open-back reference headphones, with the acoustical isolation of closed-back headphones
- Self-adjusting headband fits nearly anyone
- Low 55-ohm impedance means a higher listening level for quiet source material
- Fully detachable, replaceable cord
- Classic gold and black design
- Standard 1/8" plug with included 1/4" adapter

Your headphones can have a serious impact on your performance, so why not invest in a studio standard pair? With a classic design that's graced professional studios since 1975, AKG has elevated the humble headphone to icon status.

When will I receive my shipment?

We ship on business days (Saturday, Sunday, and holidays are not business days). Packages ship from Mississippi, Nevada, New Jersey, or Ohio -- we cannot guarantee that any product will ship from a specific warehouse. Expedited Shipping (1-Day Air and 2-Day Air) is the only way to guarantee that you will receive an item within a certain time frame. Delivery estimates for expedited shipping options are listed on the product page for the item in question. All expedited shipments are delivered Monday-Friday.

Ground Shipping typically takes 1-4 business days from the date of shipment (for orders within the 48 contiguous United States). Residential ground and Free 2-Day shipments are delivered Tuesday-Saturday. Commercial ground and Free 2-Day shipments are delivered Monday-Friday. Make sure to select the proper address type for your address in checkout, as delays may occur if your selection is incorrect.

For APO/FPO customers, all orders ship via USPS. Expedited shipping is not available. Tracking for these orders is not available.

For customers shipping to a PO Box, the order may need to be shipped via USPS. For this reason, expected delivery dates cannot be guaranteed.

Do you ship to my location?

For most products shipping to the continental United States, customers may choose Ground, 2-Day Air, or 1-Day Air delivery. We also ship to Alaska and Hawaii; however, due to carrier restrictions, we cannot ground-ship to those states.

In addition, we ships to the following destinations, though some restrictions apply:

  • Canada
  • Puerto Rico
  • U.S. Territories

See instructions below for how to search the site by our eligible shipping destinations.

Note: We cannot change a shipping address on an order after it has shipped. If an order is returned because it couldn't be received at the listed shipping address, we will accept the return but will not refund the shipping charges.


We ship a lot of our most popular gear to Canada! To determine if item(s) ship to Canada, add the item(s) to your cart and enter your shipping postal code. Items that ship to Canada are sent via International Air, and delivery is typically 2-5 business days from the date of shipment.

Canadian orders are charged in U.S. dollars. Actual charges are dependent on your bank's conversion rate. Your bank may assess additional fees for international orders.

Although items shipped to Canada receive their full factory warranty, they must be returned to a United States service center for repairs. We're not responsible for any shipping or customs fees incurred in such a case.

Puerto Rico

We ship many items to Puerto Rico. To determine if item(s) ship to Puerto Rico, add the item(s) to your cart and enter your shipping zip code. Eligible items ship via International Air, and typically arrive 2-5 business days from the date of shipment.


We ship to APO/FPO addresses for free, though over-sized items may be ineligible. To determine if item(s) ship to your APO/FPO address, add the item(s) to your cart and enter your shipping zip code.

U.S. Territories

We ship eligible products to American Samoa, the Federated States of Micronesia, Guam, the Marshall Islands, the Northern Mariana Islands, Palau, and the Virgin Islands. Eligible items typically arrive 2-7 business days from the date of shipment.

What about customs fees?

Please be aware of customs fees such as taxes and duties, which are not included in our shipping charges. Customs fees vary from location to location. Please check with your local customs office for more information on the fees in your area. If you refuse to pay these fees, your order will not be delivered. We cannot refund shipping charges if an item is returned due to refusal to pay fees, and a restocking fee may be applied to cover the cost of return shipping. Customs fees are non-refundable.

Which items ship immediately?

Most orders ship the same business day your order is placed when you place a valid order before the shipping deadline.

Immediate shipment is available Monday-Friday. A valid order placed before 5 p.m. EST will ship the same day when using Ground or Free 2-Day shipping. Ground and Free 2-Day shipping orders placed after 5 p.m. EST will ship the next business day. Many orders using an expedited shipping method (2 Day Air or Next Day Air), and placed before 10 p.m. EST, will ship the same day.

Shipment and availability information updates from our warehouse to our website almost in real time. We are highly confident of the status of each item when you view a page. However, we do not reserve inventory being viewed or even placed in shopping carts, so we cannot guarantee an item's availability until you have placed your order. In particular, if you have been in the checkout area for more than about 10 minutes, we do recommend that you refresh the page to get the most current inventory prior to checking out.

What is a valid order?

A valid order is for a valid item at a valid price, placed with a credit card with complete and verifiable address and other information. Details.

Does immediate shipment mean immediate delivery?

Once an order is shipped, our carriers (Federal Express and UPS) typically guarantee a service time for when the order will be delivered to you. Our carriers have a very good record of delivering at their promised service time. We will ship immediately, and on all items, we will refund expedited shipping charges if the carrier's service levels for your chosen shipping method are not met.

If a product is in stock, is there any reason it will not ship immediately?

Exceptions are very unusual, but here are some examples of reasons that might prevent us from shipping immediately:

  • Warehouse, call center, or web operations lose power or telecom connectivity.
  • Warehouse, call center, or web operations lose capability due to adverse weather (blizzard), safety threat, or other factors.

What can I do if I don't feel you've lived up to your guarantees?

If you ever feel we have not lived up to any of our guarantees, we want to know about it -- and we want a chance to do right if we agree. Contact Us.
