They have an ear-hook design and don’t have a typical in-ear style. They have a more professional look like most in-ear monitors. You can get these headphones with a transparent clear casing on a black color scheme. Weight 0.04 lbs Clamping Force 0 lbs The IE 40 PRO have a similar design to the Shure SE215, but they sit differently inside the ear. They enter your ear canal fairly deeply and they feel more like typical in-ears. If you dislike the fit of these kinds of headphones, you'll likely experience similar discomfort with the IE 40 PRO. On the upside, they come with 3 tip sizes and one foam tip option as well, which some people may find more comfortable. If you can achieve a good fit, they are very lightweight and you can barely feel the headphones sitting inside your ears. OS Compatibility No Controls Ease Of Use No Controls Feedback No Controls Call/Music Control No Volume Control No Microphone Control No Channel Mixing No Noise Cancelling Control No Talk-Through No Additional Controls No These headphones do not have an in-line remote with controls. Avg.Temp.Difference 0.8 °C Like most in-ears, these headphones don’t trap heat inside your ears and they stay fairly cool during long listening sessions. This makes them a decent option for sports as they won’t make you sweat more than usual. You shouldn’t notice a big difference in temperature when wearing them. L 2" W 2.1" H 0.8" Volume 3 in³ Transmitter Required No These headphones can easily fit in pockets or a bag, like most in-ears. They also come with a small pouch that doesn’t add too much bulk and can fit in most pockets. Type Pouch L N/A W N/A H N/A Volume N/A These headphones come with a small pouch that resembles that of the Jaybird X4 and Jaybird Tarah Pro. It slightly protects the headphones from scratches and minor water exposure, but won’t protect that well against physical damage from falls. The Sennheiser IE 40 PRO are well-built in-ears, but aren’t quite on par with the Shure SE215 or MOONDROP KATO. The buds are dense, but the material used doesn’t feel as durable. Also, even if their cable is detachable, it is fairly easy to accidentally disconnect it from the earbuds when not around your ears. This gives it a cheap feeling since the connection doesn’t feel secure and you might easily lose the earbuds. They still feel durable and sturdy, but they aren't the best-built option. The ear-hook design of the IE 40 PRO helps with their stability. They shouldn’t fall to the ground when using them for running. However, head movement might make the buds move inside your ear a bit. They should be fine for the occasional jog, but this wasn’t their intended use. Although the cable could easily disconnect from the earbuds, they are more secure (and won't detach as easily) when wrapped around your ears.
Sound Bass Amount -2.26 dB Treble Amount -1.73 dB Avg. Std. Deviation 0.27 dB The frequency response consistency is excellent. If the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, then they should be able to get consistent bass and treble delivery every time they use the headphones. Std. Err. 2.86 dB Low-Frequency Extension 45.55 Hz Low-Bass -4.91 dB Mid-Bass 0.07 dB High-Bass 2.93 dB The bass performance of these headphones is good. LFE (low-frequency extension) is at 45Hz, which is decent. This and the 5dB dip in low-bass indicates that they might be lacking in sub-bass and thump and rumble common to bass-heavy genres like dubstep and EDM. There’s a tilt favoring higher bass frequencies, making the overall bass light on thump but slightly boomy. Std. Err. 1.63 dB Low-Mid 2.45 dB Mid-Mid -0.01 dB High-Mid -0.09 dB The mid-range of the IE 40 PRO is very good. The 3dB bump in low-mid is actually the continuation of the high-bass overemphasis. This tends to thicken the vocals and lead instruments and make the overall mix sound slightly cluttered. However, mid-mid and high-mid are much better balanced, meaning the upper harmonics of vocals/leads will be reproduced properly. Std. Err. 2.97 dB Low-Treble -3.52 dB Mid-Treble -0.15 dB High-Treble -1.34 dB The IE 40 PRO have a decent treble range. The response throughout the range is fairly flat and even until 10kHz. There’s a small dip in low-treble that will negatively affect the detail and brightness of vocals and leads. The high peak starting at 9kHz will also make sibilants (S and T sounds) overly sharp and piercing, especially on already bright tracks. However, not everyone will hear this as intensely. Peaks 1.02 dB Dips 1.21 dB Weighted Group Delay 0.17 Weighted Amplitude Mismatch 1.24 Weighted Frequency Mismatch 1.9 Weighted Phase Mismatch 1.44 The stereo imaging performance is great. The weighted group delay is at 0.17, which is very low. The GD graph also shows that the entire group delay response is below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit were very well-matched, which is important for the accurate placement and localization of objects (instruments, voice, footsteps) in the stereo image. However, these results are only valid for our unit and yours might perform differently. PRTF Accuracy (Std. Dev.) N/A PRTF Size (Avg.) N/A PRTF Distance N/A Openness Acoustic Space Excitation The soundstage is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods (2nd generation) Truly Wireless, or the Bose SoundSport Free Truly Wireless. Head Modeling No Speaker Modeling No Room Ambience No Head Tracking No Virtual Surround No App WHD @ 90 0.135 WHD @ 100 0.046 Firmware No Firmware Power Passive Connection Wired Codec PCM, 24-bit, 48kHz EQ No EQ ANC No ANC Tip/Pad Silicone (small) Microphone No Microphone Isolation Overall Attenuation -16.82 dB Noise Cancelling No Bass -2.43 dB Mid -17.96 dB Treble -31.63 dB The isolation performance of the IE 40 PRO is decent. In the bass range, where the rumble of airplane and bus engines sits, they isolate by about 2dB, which is negligible. In the mid-range, important for blocking out speech, they reduce outside noise by 18dB, which is good. In the treble range, occupied by sharp sounds like S and Ts, and fan noises like A/C systems, they achieve more than 32dB of isolation, which is also good. Overall Leakage @ 1ft 26.01 dB The leakage performance is excellent. Like most other closed-back in-ears, these headphones don't leak in the bass and mid-ranges. The significant portion of their leakage is in treble in a very narrow range. The overall level of the leakage is very quiet too. With the music at 100dB SPL, the leakage at 1 foot away averages at 26dB SPL and peaks at around 44dB SPL, which is lower than the noise floor of most offices.
