Beats Solo3 Wireless vs Sennheiser HD 4.40 BT Wireless Comparison

Beats by Dre are one of the most popular headphone brands in the world. Their success is due in large part to their marketing as well as their product design. These trendy looking, portable headphones are big business and the compact folding design and hard hitting bass make them a hot item. The Beats Solo3 Wireless have both of these features on top of being wireless which is what makes them such a desirable headphone model.

Recently Sennheiser has been putting their own twist on the stylish portable headphone with their HD 4 Series. Their slim headband, folding body and punchy bass make them worthy of a match-up against Apple’s Beats by Dre and specifically the Sennheiser HD 4.40 BT Wireless would make an interesting match-up against the Beats Solo3 Wireless. So let’s put them side-by-side, compare features and figure out which has the best sound and most of all… the best bass.

Sennheiser HD 4.40 BT Wireless

The HD 4.40 BT Wireless is called an “around the ear” headphone by Sennheiser although it is a compact design and cutting it close to almost being an on-ear. The padding on the earcups is quite a bit softer than the Beats Solo3 Wireless which is definitely a plus. The 4.40 BT Wireless lasts up to 25 hours on a charge and uses Bluetooth 4.0 for quick connection to smartphones or wireless devices. This headphone also includes wireless NFC connection for capable devices as well. The HD 4.40 BT comes with a carry bag instead of a case.

Overall the features and specifications are very similar between the two wireless headphones. The HD 4.40 BT also has one other advantage over the Beats as you can use the free CapTune app for smartphones to customize your sound and preferences. It even integrates with your music library and can connect directly to your TIDAL account.

Battle of the Bass Headphones

Now to get down to the sound test between the Beats Solo3 Wireless and the Sennheiser HD 4.40 BT Wireless headphones. For the test we used the very popular Spotify playlist “Rap Caviar” and selected a number of tracks to try on both headphones. We’ve compared both headphones indoors and outdoors using the same mobile device which is an Apple iPhone 6S.


After running both headphones through the paces, the Sennheiser HD 4.40 BT Wireless came out on top. This headphone not only has bigger and better bass but the full-range of frequencies all the way up to the high end make quite an impression. When it comes to sound, and especially big bass, the Beats Solo3 Wireless just didn’t match up. It’s a great headphone with a solid sound but just didn’t match the audio quality of the HD 4.40 BT Wireless.

Final Comparison

Both the Beats Solo3 Wireless and the Sennheiser HD 4.40 BT Wireless headphones were comfortable with great sound and functioned well. In the end the Sennheiser HD 4.40 BT Wireless is an all around better headphone due to durability, slightly better comfort, intense bass and a full range frequency response that will get you moving. Despite the difference in battery life (40hrs for Beats over 25hrs on Sennheiser) the sound of the Sennheiser headphone is where it’s at. And with an MSRP of $149.95 the HD 4.40 BT is miles ahead in terms of value than the Beats Solo3 Wireless at an MSRP of $299. Shop the Sennheiser Headphone Store at Audio46.
