Best Headphones with Wired and Wireless Options
Published: June 25, 2025 | Category: Buying Guides
Some headphones come in both wired and wireless versions: the Sennheiser HD 660S2 (wired only) vs HD 660S2 BT ($599, wireless). The Beyerdynamic DT 900 Pro X (wired) vs DT 900 Pro X BT (wireless). Here’s why the wireless version costs 50% more and whether the upgrade is worth it.
The Price Gap
Wireless versions add: Bluetooth chip ($15-30), ANC processor ($20-40), battery ($10-20), wireless antenna ($5-10), and firmware development costs. Total additional cost: $50-100 in components. But the retail markup is $150-300 — you’re paying 2-3x the component cost for the wireless feature. The Sennheiser HD 660S2 ($399 wired) vs HD 660S2 BT ($599 wireless) is a $200 premium for Bluetooth.
Sound Quality Impact
Wireless adds a DAC and Bluetooth codec compression, which degrades sound quality vs wired. The Sennheiser HD 660S2 BT uses aptX Adaptive (576kbps max) vs the wired version’s uncompressed audio (1411kbps CD-quality). The difference is audible in blind tests — trained listeners prefer the wired version 70% of the time. But for casual listening, the difference is subtle.
My Take
Here’s my take: buy the wired version if you listen at a desk with a DAC/amp. Buy the wireless version if you need mobility and ANC. The $200 premium for wireless is steep but justified if you commute or travel. For home listening, the wired version sounds better and costs less. The rule: wired for quality, wireless for convenience. Choose based on your primary use case.
