Marvelous!‌ DALI’s Stunning New Wireless Headphones Now Available In U.S.

Today, Lenbrook Americas officially launched DALI‌’s new IO headphones to the U.S. market. IO‌ is the Denmark-based company’s first headphone line, incorporating engineering and tech drawn from over 30 years of speaker design.

There will initially be two wireless over-ear models available:‌ The IO-6 at $499 U.S. MSRP with Active Noise Canceling and the IO-4 at $399 offering similar features and performance without ANC. Shipping is scheduled to begin in November.

The IO-4 Driver

Both models will feature DALI’s proprietary 50mm paper fiber cone drivers, Bluetooth 5.0 with aptX HD, USB-C charging and Clear Voice Communication tech for phone calls. The USB-C connection can also be used as a digital connection for computer audio. Battery life is rated up to 30 hours on the IO-6 and up to 60 hours on the IO-4, and both will be available in Caramel White or Iron Black colors.  

The IO headphones were launched in Europe at IFA Berlin back in September, and initial reviews have been positive. For more information, visit

Pickering Ontario, Canada October 29, 2019Lenbrook Americas today formally announced the launch of DALI IO headphones to the U.S. market. Two “over ear” models to start, the IO-6 ($499 U.S. MSRP) is an Active Noise Canceling (ANC) wireless headphone while the IO-4 ($399) offers similar features and performance without ANC. Designed for the modern music lover, both IO models deliver remarkable sound quality utilizing a large 50mm driver with Neodymium magnet in a closedback design. Bluetooth 5.0, AAC and aptX HD provide wireless freedom and convenience though either model can be used wired, if so desired. The IO models are offered in choice of Iron Black or Caramel White and available to order now, with deliveries commencing in November.

The company leveraged their decades of speaker expertise with the IO headphones by taking a ground up approach in how to improve on the state of the art. Starting with a customdesigned 50mm driver, utilized in both the IO-6 and IO-4, DALI engineers chose a paper fiber diaphragm, similar to what is found in their most expensive speaker designs. They then used an optimized neodymium magnet system to achieve low distortion, minimal coloration and accurate dynamics.

Connectivity DALI IO headphones are designed primarily with wireless Bluetooth use in mind. For the best possible Bluetooth performance, they support the latest high-quality audio codecs: AptX, AptX HD and Apple AAC. For fast battery charging and best possible quality, DALI IO headphones use a USB-C connector which supports digital audio and allows music to be streamed in CD quality from a Windows or Mac OS computer. Use of a USB-C connector also avoids the common failures with micro-USB connectors resulting from incorrect insertion.

In addition to Bluetooth and USB connection, IO headphones also incorporate a traditional wired analog jack input located on the left ear cup. The wired input enables connection to legacy sources and in-flight entertainment systems and works when the headphones are switched either on or off. When the headphones are switched “off” they operate in a simple passive mode; none of its control functions will be operational. Use in passive mode means that a drained battery need not interrupt headphone listening.

Ease of Use DALI engineers also focused on ease of use and intuitive operation. Their design solution was to have the three main control buttons elegantly integrated into the design of the right ear cup. The logo plate is the multi-function button for controlling Play, Pause, Next, Previous, Take Call and End Call. The upper and lower part of the ear cup outer ring, which surrounds the logo plate, control Volume Up and Down respectively. To further support the user experience, the IO headphones feature voice prompts that provide feedback on the state of operation, connectivity, battery level and ANC mode (IO-6 only). On/Off, Pairing and Battery Level are also indicated visually by two multicolor LED indicators on the right ear cup.

Comfort – The best-sounding headphones are less compelling if they are not comfortable to use for long periods of time. For IO models, DALI chose a circumaural (aka over ear) format which surrounds the ears and rests on the head. This maximizes comfort while reducing air leakage to retain sound. DALI then designed ear pads constructed from memory foam, where a comfortable, acoustically superior seal over the ears is guaranteed. This, in turn, ensures perfect sonic performance, while the soft synthetic leather finish adds maximum durability. With all headphones susceptible to bass leakage, leading to low-frequency variations, DALI IO’s ear pads have been designed specifically to deliver sound with minimum bass leakage, ensuring the audio will always sound as originally intended.

IO-6 vs IO-4 Design DifferencesWhile both DALI IO-6 and DALI IO-4 offer the same level of cutting-edge audio technologies for the ultimate in high-performance, the IO-6 differs from the IO-4 by incorporating active noise cancellation (ANC), to cut out any sound disturbances from the outside world as well as adding a separate, more powerful, amplification section. However, in forgoing ANC, the IO-4 is able to double its battery life to an incredible 60-hours per charge.

To complete the package, IO models are supplied with:

USB-C cable for charging and computer audio use, as well as

3.5mm jack cable for connection to traditional audio sources and in-flight entertainment systems

High-quality travel case to protect the headphones when not in use. (IO-6 only)

Clearly, the personal audio market in recent years has been a strong growth category and one that DALI has researched carefully”, commented Jeff Earl, DALI Product Manager for Lenbrook Americas. With the IO headphones, DALI leverages its 35 years of related experience in transducer expertise, audio technology and advanced design to create exceptional headphones that deliver power, performance, comfort and style.”
