Sennheiser PMX 684i Fitness Workout Sports Earbuds : A Lightweight Sports Earbud that Packs a Punch

If you’re an active fitness buff looking for a solid pair of sports earbuds, the Sennheiser PMX 684i should be on your radar. This lightweight wireless earbud is specially designed for the modern athlete. Let’s dig into the nitty-gritty details in this review.

Design and Features

The Sennheiser PMX 684i Earbuds features an ultra-lightweight neckband design that stays secure during your workout, making it perfect for running, biking, skating, and hitting the gym. The sweat and water resistant construction holds up to intense activity and can even be rinsed clean after use.

The in-ear design provides a snug ergonomic fit so you don’t have to worry about earbuds falling out mid-sprint. The angled position also allows you to maintain awareness of your surroundings, an important safety feature for outdoor runners and cyclists.

An inline smart remote gives you convenient control over music playback and phone calls, with volume adjustment and a built-in mic.

Lightweight and Secure Design

The Sennheiser PMX 684i earbuds are designed to be incredibly lightweight and secure. The neckband design ensures that the earbuds stay in place even during vigorous activity. This is a major advantage over traditional earbuds, which can easily fall out during workouts. The lightweight construction also helps to prevent discomfort during long workouts.

Many users praise the PMX 684i for its comfortable and secure fit. One reviewer who uses them for running says, “These are the first pair I’ve ever had that wrap around the back, and they’re great! I rarely have to adjust them.” This sentiment is echoed by other users who appreciate the stability of the neckband design, especially during high-impact activities.

Sweat and Water Resistance

Sweat and water resistance are essential features for any sports earbuds. The PMX 684i earbuds are designed to withstand the elements, making them perfect for intense training sessions or outdoor activities in various weather conditions. This durability ensures that your earbuds will continue to perform reliably even during the toughest workouts.

Users have reported using the PMX 684i in a variety of conditions, from sweaty gym sessions to rainy runs, with no issues. One reviewer states, “I have not had any issue with sweat causing any problems,” highlighting the earbuds’ ability to withstand moisture. This feature provides peace of mind, knowing your investment is protected from the elements.

Passive Noise Isolation

While the PMX 684i doesn’t offer active noise cancellation, its in-ear design provides a degree of passive noise isolation. This helps to block out distractions and allows you to focus on your music. However, it’s important to note that the earbuds are designed to allow some ambient sound to pass through. This is crucial for safety reasons when exercising outdoors, as it allows you to remain aware of your surroundings.

Some users appreciate the balance between noise isolation and ambient awareness. As one reviewer puts it, “the earbuds are slightly angled, allowing me to hear the environment around me, in addition to listening to music.” This feature is particularly important for runners and cyclists who need to be aware of traffic and other potential hazards.

Smart Remote and Microphone

The PMX 684i features an integrated inline remote and microphone. This allows you to easily control music playback and answer calls without having to reach for your device. However, it’s important to note that the full functionality of the remote is designed for Apple devices. Android users may find that some of the controls, such as volume adjustment, do not work.

Despite the limitations for Android users, the microphone functionality is generally well-regarded. One reviewer notes that the microphone “adequately picks up my voice when on calls,” but advises shielding it from wind noise. This is a common issue with microphones on wired earbuds, and using the included cable clip can help to minimize wind interference.

Durable Construction

Durability is a key consideration for sports earbuds. The PMX 684i is built to withstand the rigors of regular use, with features like reinforced cables and a robust design. This ensures that your earbuds will last, even with frequent use during intense workouts.

While many users praise the durability of the PMX 684i, some have reported issues with the headphone jack. One reviewer notes that the “headphone jack itself seems rather weak” and cautions users to be careful to avoid damage. This highlights the importance of handling the earbuds with care, especially when connecting and disconnecting them from your device.

Open Sound and Compatibility

The PMX 684i features an “open” sound design, which means that it allows some ambient sound to pass through. This is beneficial for safety reasons, especially when exercising outdoors. It also helps to prevent the feeling of pressure that some people experience with traditional in-ear headphones.

While optimized for Apple devices, the PMX 684i is compatible with a wide range of devices thanks to its 3.5mm headphone jack. This includes Android phones, MP3 players, and even gym equipment. However, it’s important to note that the inline remote controls may not function fully with non-Apple devices.

Overall, the Sennheiser PMX 684i earbuds offer a compelling combination of features for athletes and active individuals. Their lightweight and secure design, sweat and water resistance, and durable construction make them ideal for use during workouts. While the passive noise isolation and open sound design prioritize safety and awareness, the smart remote and microphone provide convenient control and communication options. Although optimized for Apple devices, the wide compatibility ensures that these earbuds can be enjoyed by a broad range of users seeking a reliable and high-performing audio solution for their active lifestyle.
