If you want in-ear isolation and a flexible over-ear cable for call center listening, choose Audio-Technica ATH-E70; if you need closed-back, over-ear headphones for extended monitoring, choose Focal Lensys Professional Closed-Back. For a call center, neither is a Bluetooth headset: both are wired, so the better fit comes down to whether you prefer compact earphones or full-size headphones.
• Audio-Technica ATH-E70: Three balanced armature drivers and an around-the-ear fit are its strengths; its in-ear design may not suit listeners who dislike ear tips.
• Focal Lensys Professional Closed-Back: Over-ear cups, Al/Mg drivers, and memory foam earpads make it the full-size option; it takes up more space than an in-ear model.
• The ATH-E70’s detachable 1.6 m cable is a practical feature, but it is still a wired earphone rather than a wireless call-center headset.
• Lensys has a stated frequency range of 5 Hz–22 kHz, while the ATH-E70 is listed at 20 Hz–19,000 Hz; those figures describe range, not a guarantee of better call quality.
• Choose the ATH-E70 if you want compact, isolating earphones; choose Lensys if you prefer cushioned over-ear headphones for monitoring and playback.
The ATH-E70 is an in-ear monitor built around three balanced armature drivers. Audio-Technica describes it as suited to monitoring and mixing, with accurate response across the frequency range. That makes the design a considered choice for someone who wants to hear audio details while working, rather than a headset built around wireless convenience or call controls.
Its housings are designed to isolate sound, and the cable loops over the ears with a flexible memory section intended to support a custom fit. In a work setting, that combination may appeal if you want earphones for call center listening and prefer a compact setup over headphones with earcups. The fit depends on using ear tips, and the set includes silicone options in XS, S, M, and L, plus a medium Comply foam tip. A carrying case is included for storage between work sessions.
The cable is detachable, measures 1.6 m (5.2 feet), and connects to the earpieces with A2DC connectors. The package also includes a 6.3 mm (1/4-inch) plug-on adapter. These are useful details for monitoring setups with compatible connections, but they do not turn the ATH-E70 into a wireless device. Its listed frequency range is 20 Hz–19,000 Hz, with 39-ohm impedance.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Who should skip it: Skip the ATH-E70 if you don’t want ear tips in your ears or specifically need a Bluetooth headset for call center work.
Lensys Professional is a wired, closed-back, circumaural headphone. In practical terms, it sits over the ears rather than inside them. Focal specifies Al/Mg speaker drivers, memory foam earpads, and a sturdy but flexible headband. That construction points toward listeners who want a full-size fit for monitoring sessions, studio work, or playback and who value cushioned ear contact over the compact form of an in-ear monitor.
The closed-back design is described as providing sound isolation. That may be helpful when you want to concentrate on the audio in a studio or another listening environment, though the information provided does not establish a particular level of noise reduction. The memory foam earpads are a clear difference from the ATH-E70’s ear-tip fit: they rest around the ears, so the comfort question is largely about your preference for over-ear cups rather than in-ear seals.
Focal lists a frequency range of 5 Hz–22 kHz and an impedance of 26 ohms. The headphones use a 3.5 mm jack and are wired; a protective case is included. Their fuller over-ear design may make them a more natural fit for a desk or studio setup than for someone seeking a small pair of earphones to carry around. Like the ATH-E70, Lensys is not described as a Bluetooth product.
Who should skip it: Skip Lensys if you need in-ear earphones, a lightweight-to-pack compact form, or wireless call-center connectivity.
• Best fit if you prefer earphones for call center listening → Audio-Technica ATH-E70. It uses in-ear earpieces with included silicone and foam tips, while Lensys has over-ear cups.
• Best fit if you prefer padded over-ear headphones → Focal Lensys Professional Closed-Back. Its memory foam earpads and flexible headband distinguish it from the ATH-E70’s ear-tip and around-the-ear cable design.
• Best for a detachable cable → Audio-Technica ATH-E70. Its 1.6 m cable detaches at the earpieces through A2DC connectors.
• Best for a stated frequency range extending lower and higher → Focal Lensys. Its listed range is 5 Hz–22 kHz, compared with 20 Hz–19,000 Hz for the ATH-E70. This is a specification difference, not proof that one will sound better to every listener.
• Best for included ear-tip choices → Audio-Technica ATH-E70. The package includes four silicone tip sizes and a medium Comply foam tip.
• Best for a closed-back, over-ear monitoring setup → Focal Lensys. Its design is explicitly circumaural and closed-back, with isolation described as part of the design.
• Best for an included 6.3 mm adapter → Audio-Technica ATH-E70. Its package includes a plug-on adapter for compatible equipment; Lensys is listed with a 3.5 mm jack.
• Best if you are shopping for waterproof headphones for call center use → Neither based on the listed information. Neither product’s provided details establish waterproofing, so I would not choose either on that requirement.
My Verdict
I’d choose Focal Lensys instead if I preferred over-ear comfort and a closed-back headphone for desk-based monitoring. Neither is a Bluetooth headset, so my call-center recommendation is about fit and wired listening—not wireless calling features.
The first question is how you want the product to sit on your head. The ATH-E70 uses in-ear earpieces, with a cable that loops over the ears. Its supplied tip options let you choose among several silicone sizes or the included medium foam tip. That variety is useful if fit is the deciding factor, but it does not remove the basic fact that the earpieces sit inside the ears.
Lensys takes the opposite approach. Its cups sit over the ears and use memory foam earpads, with a flexible headband. If you work at a desk and already prefer full-size headphones, that design may feel like the more intuitive match. If you want to keep a small listening setup in a bag, the ATH-E70’s in-ear format may be easier to accommodate. Both products include a case, though the provided details do not specify comparative case dimensions.
Next, consider the connection. Both are wired. The ATH-E70 has a detachable 1.6 m cable and includes a 6.3 mm adapter; Lensys is listed with a 3.5 mm jack. Check that the connector works with your intended audio device before choosing. Neither product’s listed details establish Bluetooth connectivity, a microphone, or call-handling controls, so don’t assume either provides the functions of a dedicated call-center headset.
Finally, treat isolation and frequency range as descriptions of design, not promises about your specific workplace. The ATH-E70’s housing is designed for isolation, and Lensys is described as closed-back with sound isolation. Neither data set supplies a measured noise-reduction figure. Likewise, their frequency ranges are not a substitute for listening preferences or compatibility checks. If your main goal is answering calls hands-free, confirm that the product and your equipment support that use before making a decision.
The ATH-E70 is the in-ear choice, while Lensys is the over-ear choice. Both are listed as wired, and the supplied information does not identify either as a Bluetooth headset or specify a microphone.
Both are described as having sound-isolating designs: the ATH-E70 uses specially designed housings, and Lensys is closed-back. No measured isolation level is provided, so the specifications do not establish which blocks more sound in a particular office.
The listed product details do not state that either model is waterproof. If water resistance is essential, don’t treat either as suitable based on the information here.
Choose Focal Lensys if you want over-ear cups with memory foam earpads and a flexible headband. Choose the ATH-E70 if you prefer in-ear earphones and are comfortable selecting and wearing ear tips.
