SennheiserConsumer Audio HD 4.40 Around Ear Bluetooth Wireless Headphones - Black

The Short: Affordable, dependable, over-ear bluetooth headphones with high usability, rich sound with good separation from trusted brand in audio.I run a professional video and photography production company, and use these headphones on a daily basis for both editing and entertainment. If you are considering this pair of headphones, odds are you are simply looking for a pair of wireless bluetooth headphones with the best quality sound that can hold up to casual daily use. Congratulations, you’ve found it.The tech specs are readily found on Amazon and Google, so I won’t get into the technical side in this review. Instead, I will talk about (1) build quality + durability, (2) reliability, (3) sound quality, (4) usability, (5) comfort, and (6) transportability.1. Build Quality + DurabilityThe headphones are made with hard plastic all around; there are no visible metal parts on the headphones. They are lightweight, but overall construction feels solid and the plastic feels and looks like high-quality plastic and not cheap and toy-like. I travel a lot for my work — spending my days between editing out of coffee shops to flying across the country on production. The headphones either travel with me around my neck, folded in my padded equipment bag, or folded into my daily commuter backpack without any hard case around it. In all instances, over the last 2 months of daily use, I have never had any issues with the headphones nor have I had to worry about them not holding up to travel. So far so good!2. ReliabilityOne of the most important factors for me in choosing a bluetooth wireless headphone was the reliability of the connection. I grade this on (a) the connection strength of the headphones and (b) the ability of the headphones to connect with my devices every time. These headphones have performed with perfect marks across the board in both categories. I’m an Apple user, and use these headphones daily between my iMac desktop, MacBook Air laptop, and my iPhone X. The bluetooth connection is always solid, and the sound coming through is clear with no audible lag, distortion, nor interference. If using with just one device, the headphones will pair quickly and automatically, which is nice. Switching between each device has been super easy for me — just hold the power button down when turning the headphones on to place the headphones into pairing mode, then select the headphones from your device’s bluetooth pairing menu.3. Sound QualityThese have great sound clarity, rich midtones, controlled highs, full base (but not overwhelming), and remarkable sound separation. The headphones may be used both wirelessly, or with the wire that comes with the headphones. As with all wireless/bluetooth headphones, the audio quality is always better if directly connected to the device. However, these headphones do a truly fantastic job of preserving audio quality in wireless bluetooth mode. I would say there is a negligible difference in sound quality between wired and wireless, which is really only noticeable if you are comparing it side-by-side. I was a long-time user of the Beyerdynamic DT 770 PRO 80 Ohm wired studio monitoring headphones, which are still my headphones of choice when monitoring sound on film productions due to its flatter profile which allows me to hear frequencies on a or even spectrum. On the contrary, the Sennheiser HD 4.40’s noticeably richer and more responsive tones and fuller base makes it more enjoyable to listen to, despite being less than HALF the price. If you want a pair of headphones that enable you to ENJOY your sound and not just monitor it, I definitely recommend these headphones. Even in their wireless mode, these headphones have allowed me to hear and feel MORE from old music I’ve heard many times before.4. UsabilityI spend a lot fo my time between my desktop, laptop, and cell phone for work. The pairing and switching process is super easy., and I have never had any issues with these headphones with any of my devices. I have used these for a full day of flying and traveling, and did not run into any issues with battery life, which Sennheiser boasts as having up to 25 hours of battery life while in wireless mode. The controls on the right ear cup of the headphones are easy to access for me, though toggling them produces an audible “beep” from the headphones while in wireless mode. Many of complained about how annoying this beep is, but I personally don’t mind having audible feedback to my input. Using the headphones in wired mode disables the functionality of the buttons on the right ear cup, thereby eliminating the “beep.”5. ComfortThe ear cups that come with the headphones are made of a supportive but super soft memory-foam type material, covered by a smooth and high-quality feeling stitched pleather material. Many of complained that the ear cups are too small to fit over their ears, and should therefore be considered on-ear headphones, though I have never had that problem myself based on my ear-size. My ONLY complaint is that the padding on the bottom of the headband where the band touches the head does not have very much padding, which can create some discomfort when wearing over a long period of time. I have the headphones at their max extension to avoid tension from the headband hurting the top of my head. The headphones stay on my head very well and does not slip around despite being on the widest setting.6. TransportabilityTo transport, the headphone’s ear cups fold INTO itself, though the ear cups do not fold flat. As a result, they produce a taller profile vs. headphones that fold flat. When I travel, the headphones are either around my neck for ease of access, or folded and placed into my padded equipment case, equipment backpack, or simply tossed into my daily commuter backpack. They really are a fantastic pair of wireless bluetooth headphones for the commuter and daily user who wants to enjoy their sound.--------------------------------Conclusion:For their price range ($70 at the time of this review), they are really hard to beat. If you are looking for a pair of headphones for entertainment and not professional/commercial use, it's hard to go wrong with the Sennheiser HD 4.40. Great for the commuter and daily user. Would buy again.
